9Master Data and Application in Distribution
Planning and PP (overview)
- Master Data for Distribution Planning
- Location, Product, Resource, Transportation lane,
Quota arrangement, and Interchangeability group. - Master data for Production Planning
- Location, Product, Resource, PPM/PDS , Quota
arrangement, Set up Group matrix, and
Interchangeability group.
10Master Data and Application in Distribution
Planning and PP (Overview)
- Transportation lanes
- Transportation lanes are required from plant and
distribution center to the transportation zone
and have to be created manually. - The allowed carriers have to be assigned per
means of transport and transportation lane
explicitly. - Quota arrangement (vendorss quota)
- Quota arrangement must be used, if it is intended
to source from multiple locations on a regular
basis. - The concerned products are assigned to the quota
arrangement, and the ratio of the resources is
defined per product.

12Distribution (and Supply Chain) Planning
- Distribution planning between the manufacturing
plants and warehouses is important, as companies
reduce inventory by changing their logistics
processes to global inventory management, from
non-coordinated local inventory management. - Distribution (and supply chain) planning focuses
on make-to-stock production.
13Distribution ( Supply Chain) Planning, and
Replenishment
14Process Chain for Distribution and Supply Chain
Planning
15Distribution and Supply Chain Planning
- Distribution planning is performed based on
demand and stock information with the result of
planned stock transfers. - The most important issues are usually the netting
of the local stocks, safety stock levels,
sourcing options, transportation times and lot
sizes for the planned stock transfers. - If required, restrictions are considered
regarding storage capacity and handling capacity
for goods issue and goods receipt.
16Distribution and Supply Chain Planning
- Replenishment involves two processes
- Deployment, and
- Deployment is concerned with the fair share of
quantities to the requesting parties in case of
shortage or surplus. The constraints are
available quantities. - Transport load building.
- Transport load building is one step closer to
execution and focuses on the creation of truck
loads, where the task is to adjust the planned
stock transports to the available
trucks/transport means and take their capacity
restrictions into account.
17Distribution and Supply Chain Planning
- SAP APO supports distribution and production
planning, with the following 4 applications - For distribution
- SNP heuristic
- PP/DS heuristics
- For SCP
- SNP optimizer
- CTM (with SNP or PP/DS master data)
18Applications for Distribution and Supply Chain
Planning
19Features of the Application for Distribution
20Distribution and Supply Chain Planning
- Distribution planning with SNP heuristic is often
used in the environments where multiple sourcing
is not an issue and production is usually able to
meet the demands, so that the main task for SNP
heuristic is to calculate the demands for
production planning based on local inventories,
transportation times, safety stocks and lot
sizes. - SNP optimization allows a complete consideration
of the supply chain determinants (i.e., sources
and cost, production capacity, transport, storage
and handling). The aim of SNP optimizer is to
find a global optimum for supply chain based on
cost and penalty cost. - CTM pursues a priority based simple rules such as
FIFS.
21Order Cycle for Stock Transfer
22Order Cycle for Stock Transfers
The stock transfer order has two aspects as a
demand in the source location and as a supply in
the target location. The documents differ in SAP
ERP and SAP APO. The creation of the planned
stock transfer, deployment and transport load
building (TLB) is performed in SAP APO. The
execution part from the creation of the outbound
delivery in the source location until the goods
receipt in the target location is performed in
SAP ERP, and the information is displayed in SAP
APO.
23Order Cycle for Stock Transfers
- Three order types in SAP APO
- Planned stock transfer,
- Deployment confirmed stock transfer and
- TLB-confirmed stock transfer
- They are matched to
- the stock transfer requisition and
- the stock transfer order in SAP ERP, according to
the setting for SNP transfer.
24Order Flow for Stock Transfer on SAP ERP side
25Stock Transfer Order
Stock transfer order is first scheduled in SAP
APO, then transferred to SAP ERP and scheduled
again in SAP ERP according to the delivery date.
The scheduled dates in SAP ERP are not
transferred back to SAP APO. Stock transfers
are executed according to the order dates in SAP
ERP, therefore it is important to keep the
scheduling in SAP APO and SAP ERP consistent.
The transport duration in SAP APO is calculated
using the entry from the transportation lane,
whereas SAP ERP uses the planned delivery time of
the material master of the target location.
26Stock Transfer Scheduling

27Setting for Stock Transfer within and across
Company Codes in SAP ERP
Since SAP APO does not know any company codes,
there is no difference in SAP APO whether stock
transfers are planned within one company code or
across company codes. On SAP ERP side,
cross-company stock transfers require the
additional settings. The assignment of the sales
area and the customer to the plant is made with
maintenance view V_001W_IV.
28Setting for Stock Transfer within and across
Company Codes in SAP ERP
29Setting for Stock Transfer Across Systems
Stock transfer across two SAP ERP systems is
modelled by a purchase order in the target plant
and a sales order in the source plant.

32Production Master Data Overview
- The relevant master data for production planning
- Location
- Product
- Resources
- PPM and PDS
- Quota arrangement,
- Set up Group matrix, and
- Interchangeability group.
- Note on resources
- SNP and PP/DS have a different view of the
capacity. - SNP in buckets
- PP/DS time-continuous capacity
-
33Resources for SNP
The idea of SNP is to perform an aggregated
planning. Since SNP is an application for
bucket-oriented planning, the resources for SNP
offer a certain capacity per time bucket
usually per day. The bucket resources provide the
capacity e.g. the amount of working hours per
day of the resource which is used for the
capacity consumption of the orders. For the
scheduling of the production orders, the factory
calendar is assigned to the resources. The
standard capacity is defined in the resource
master. Figure 13.13 shows these setting for the
bucket resource. Another way to define the
capacity is the use of a reference resource to
save time.
34Settings for a Bucket Resource
35Resources for PP/DS
In PP/DS, scheduling and capacity consumption are
not separate steps, but the capacity is consumed
by the scheduled operation. The basic resource
property in PP/DS is the working time, which
depends on the standard working hours, the break
time, and factory calendar. Usually the
available working time is modelled per shift, and
the shifts are assigned to a shift sequence to
model circumstances.
36Settings for PP/DS (single Resource)
37Production Master Data Overview
PPM The Production Process Model (PPM) defines
the detailed information required for
manufacturing a product. The PPM combines routing
and the bill of materials (BOM) into one master
data object. Each PPM includes one or more
operations. Each operation, in turn, includes one
or more activities, for which materials,
relationships and resources are maintained. The
activities and resources defined in the PPM are
assigned to costs that are used by the SNP
Optimizer and for finite scheduling by Production
Planning and Detailed Scheduling (PP/DS).
38Production Master Data Overview
Supply Network Planning (SNP) is a long term,
rough cut planning tool. SNP requires a PPM with
less information than the one used for production
planning and detailed scheduling
(PP/DS). During a planning run, SNP can
schedule resources down to the day. In order to
perform scheduling at the day level, the PPMs and
resources must be simplified. Additionally, when
using optimization technologies, it is important
to limit the number of inputs (materials) to find
a proper solution in a reasonable runtime. SAP
SCM allows you to generate SNP production process
models (PPMs) based on existing PP/DS PPMs.
Restriction to a specific lot size is required to
determine the exact production consumption or
mode duration.
39Production Master Data Overview
PDS (production data structure) SAP initially
developed the Production Process Model (PPM) to
model manufacturing master data. It was replaced
in SCM 4.1 by PDS. However PPMs are still
supported. In some industries modeling the
production and evolution of a certain product can
be very complicated. When a product has many
variations due to customers choosing a
combination of features and options they
typically used the variant configuration solution
in standard SAP ERP.
40Production Master Data Overview
The main motivation to develop the PDS was to
have an integration of the Engineering Change
Management (ECM) and the Variant Configuration
between SAP ERP and APO. From SCM 4.1 on, the
Production Data Structure (PDS) is the key master
data for all kinds of production planning related
processes. The PDS is supported by the
applications of PP/DS, SNP, CTM and DP. Like the
PPM, the PDS corresponds to the production
version on SAP ERP system. Though both PPM and
PDS are still available as alternatives, there is
no further development for the PPM since SCM
4.0.
41Structure of PDS and PPM
42Transfer of PPM and PDS
43Production Process Overview
- Production Planning
- Creates planned order and purchase requisition
for the demand, - Creates detailed scheduling (a sequence for the
orders which is sufficiently capacity-feasible,
usually in the short-term), - Desirably performs a rough feasibility check of
the production plan, and - execute the production plan.
- The detailed scheduling is usually only performed
for the short term horizon. - Traditionally both production planning and
scheduling are limited to the plant level.
44Production Process Overview
- If a supply chain contains alternative production
plans (possibilities), the process becomes more
complex. It often requires an integrated
distribution and production planning. - Depending on the business requirements, it might
be favourable to create a rough-cut production
plan for the mid-term or even long-term before
the more detailed production plan. - The approach represents the idea of a
hierarchical planning, i.e. to plan with less
detail for the farther future and has the
benefits of avoiding unnecessary information and
unnecessary system load and to have a tighter
integration with the distribution planning.
45Process Chain for a Make-to Stock Production
46Production Process Overview
- Objectives for Production Planning
- to meet the demand
- to consider the resource capacities and the
material availabilities - to improve utilisation of the resources
- to low set up time
- to minimise the stock, and
- to minimise the work in process (WIP)
- to improve stability of the plan
47Production Process Overview
- The complexity of production planning increases
with the number of BOM-levels, number of
operations, and finite resources, the use of
fixed, or minimized lot sizes and sequence
dependent set-up. - Though APS (Advanced planning and Scheduling)
systems allow theoretically a one-step approach,
experience shows it is better and more reliable
to use a two step approach to create a feasible
plan (i.e. infinite production planning first and
finite scheduling on the key resources later),
and keep the constraints as less as possible in
modeling and.
48Order Cycle for Production
49Order Cycle for Production
- The result of production planning are planned
orders which contain the information about the
dependent demand and the capacity requirement in
SAP APO. - The production orders are reduced by the order
confirmation and remain in SAP APO until it is
technically completed.
50Production Planning Applications
SAP APO offers different applications for
production planning and detailed scheduling.
Production planning is supported by the SNP and
PP/DS modules with two different levels of
details. - rough-cut and bucket-oriented
planning (SNP), and - time-continuous planning
(PP/DS). Detailed scheduling with the purpose of
creating a sequence for order execution is only
supported by PP/DS since SNP is limited to
bucket-oriented planning and there is no sequence
within a bucket.
51Applications for Production Planning and
Scheduling
52Production Planning Applications
- Based on the applications there are several
options for creating a feasible plan in SAP APO.
Each has its advantages and disadvantages. - Distribution and medium-term production planning
with SNP heuristic, the SNP optimiser or CTM with
SNP master data (short-term production planning
by conversion of SNP orders to PP/DS orders and
detailed scheduling with the DS heuristics or
PP/DS optimiser). - Distribution planning with SNP heuristic,
medium-term production planning with SNP
optimiser, short-term production planning by
conversion of SNP orders to PP/DS orders and
detailed scheduling with DS heuristic or PP/DS
optimiser.
53Production Planning Applications
3. Production planning for medium-term and
short-term horizon with higher level of detail in
PP/DS using PP heuristics or TM and detailed
scheduling with DS heuristic or PP/DS optimiser.
4. Demand planning in SAP ERP especially when
there is already a sufficient solution using SOP
or long-term planning. Production planning is
performed with PP heuristics, scheduling with DS
heuristics or PP/DS optimiser. 5. Demand planning
and production in SAP ERP SAP APO is used only
for scheduling.
54Production Planning Applications
6. Only medium-term production planning on
rough-cut level is performed in SAP APO either
by SNP heuristic, SNP optimiser or CTM. The
benefit is having a capacity check and purchase
requisitions for components with long lead time.
Planned orders are transferred to SAP ERP, where
production planning and scheduling on detailed
level are for the short-term horizon. 7.
Production planning is triggered by the sales
order entry either via CTP or multi-level ATP.
Scheduling is performed with scheduling
heuristics or PP/DS optimizer. Note PP/DS
optimiser is used only for scheduling, not for
creation of orders.
55Scenarios for Production Planning using Different
Applications
56Lot Size
Lot sizes have a significant impact on the
production planning result and challenges for
scheduling. The fixed, minimum and periodical lot
sizes in material master data increase the
complexity of the planning problem.
57Lot Size Methods
58Lot Size
Though CTM supports minimum and fixed lot sizes,
but CTM performs a finite planning and does not
split orders across buckets which might lead to a
very low utilisation.

60Order Cycle for Stock Transfers
The outbound delivery for the stock transfer
order is created with transaction VL10B in SAP
ERP, picking and posting of goods issue is done
with the transaction VL02N in the delivery.
Using the message type LAVA, the inbound
delivery in source location can be triggered with
posting of the goods issue (or manually with the
transaction VL31N). For the use of deliveries
it is necessary that a vendor is assigned to the
source location and that an info record exists in
SAP ERP. The inbound delivery is transferred to
SAP APO as a purchase order memo of the stock
transit.
