PDC Scenario for Store Requirements Planning
Use
With the help of store requirements planning, articles that have sold out can be replenished using a PDC unit. The general aim is to optimize the stock available in the store.
In principle, all the functions that are available in the SAP Retail Store Store Order can also be executed using the PDC interfaces for store requirements planning.
Prerequisites
The prerequisites for using the SAP Retail Store Store Order also apply for using the PDC interfaces for SAP Retail Store store requirements planning.
In particular, you must have either a full or a mixed version of the assortment list.
To use the RFC/IDoc-based PDC procedure, PDC procedure 2 needs to be selected in Customizing for the SAP Retail Store Store Order (Logistics General ® Retail Store ® Store Order ® Global Control).
Procedure
The following describes some examples of processes that can be handled using the PDC interfaces for store requirements planning and the Retail Store Store Order.
Example 1: Entering procurement quantities and generating follow-on documents
You can enter quantities on the PDC units and generate follow-on documents (for example, purchase orders) directly in SAP R/3.
Example 2: Working with default quantities and generating follow-on documents
You can generate purchase requisitions using an MRP run. The quantities from the purchase requisitions can be sent to the PDC units and used as default quantities for requirements planning in the store. The default quantities can then be revised on the PDC unit and used to generate follow-on documents in the Retail System as in example 1.
Example 3: Working with default quantities and changing/creating new purchase requisitions
As in example 2, you can generate purchase requisitions using an MRP run. The quantities from the purchase requisitions can be sent to the PDC units and used as default quantities for requirements planning in the store. These default quantities can then be revised on the PDC unit. The quantities reported back from the PDC units can be used to change existing purchase requisitions. If in this case a purchase requisition does not yet exist for a quantity that is entered, one is created automatically in the Retail System. In the SAP Retail Store Store Order the purchase requisitions that were changed/created are directly visible as default quantities and they can be checked and revised again if necessary. Follow-on documents can be generated directly from the SAP Retail Store Store Order or using a batch job at a specific point in time.
Example 4: Entering default quantities and releasing them in the Retail Store
You can also select a process that is similar to example 3 and avoid an MRP run for generating purchase requisitions. In this case, the process would be a two-stage procedure, in which a preliminary entry is made on the PDC units, is then checked in the SAP Retail Store Store Order and released by the initiation of follow-on document generation.
All of the sample processes described above require the PDC units in the store to be supplied with data first. There are two RFC interfaces available for doing this (SRS_PDC_SO_STRUCTURE and SRS_PDC_SO_OUTBOUND), which are supplied with data by programs R_SRS_PDC_ASSORT_STRUCT_OUT and R_SRS_PDC_SO_DISP_DATA_OUT. Information on existing assortment list groups is passed on using interface SRS_PDC_SO_STRUCTURE. The PDC units are supplied with article data using interface SRS_PDC_SO_OUTBOUND. If necessary, article data for individual assortment list groups can be sent manually from the SAP Retail Store Order to the PDC units.
The user can then change or enter procurement quantities on the PDC unit.
The quantities entered are then transferred to the Retail System and posted using interface SRS_PDC_SO_INBOUND. It also possible to carry out checks or corrections in the SAP Retail Store Store Order (if follow-on documents were not generated directly in the Retail System).
The provision of data to the PDC units and their confirmation can be monitored in the SAP Retail Store Store Order at assortment list group level.
Result
As a result of store requirements planning, purchase requisitions are changed or created or follow-on documents such as purchase orders are generated.
In the SAP Retail Store Order, you can monitor the assortment list groups (assortment list types, merchandise categories and so on) for which procurement data from the PDC units was confirmed.
