SAP MRP Settings for auto-generation of Stock Transfer PRs Stock Transfer PRs is an internal requisition document, used for the creation of Stock Transport Order. STO (Stock Transport Order) are purchase orders used to satisfy the requirements of one plant with another. MRP generates Stock Transfer PRs when there exist a shortage of quantity between existing stock & reorder point derived/maintained in material master. Reorder Point can be maintained manually by user/ automatically by running forecast using transaction MP30. The SAP formulae for automatic calculation of Reorder Point & Safety stock is available in the below link: https://w3-03.sso.ibm.com/services/practitionerportal/documents/Y722103M14213R07 We came across a unique requirement from client to handle a storage location with varying lot sizing procedures depending on the material, and that the safety stock & reorder point needs to be automatically forecasted for them. Since MRP at Storage location level (MRP 4 View) in Material master can facilitate only a fixed replenishment quantity and the reorder point needs to be manually entered, we decided to create a new Plant (Dependent plant) in place of the storage location and generate ST PRs (Stock Transfer PRs) to the parent Plant to satisfy the requirement of this new dependent plant.
Configuration of MRP settings to generate ST PRs: 1. Assign the Parent plant to the dependent plant for the Special procurement type ‘40’
Goto the below path in customization for the special procurement types: SPRO Material Management Consumption-Based Planning Master Data Define Special Procurement Types Once you click on ‘Define Special Procurement Types’, you get a window with Plant & Spl Proc Types. Select the dependent plant with Spl Proc Type ‘40’ and click on details ‘ Eg. Dependent plant ‘1000’ with Spl Proc Type ‘40’.
’.
Assign the Parent plant with Special procurement ‘U – Stock transfer’ as shown below: Eg. Assigned Parent plant ‘1001’ with Special procurement ‘U’ for dependent plant ‘1000’ and Spl Proc Type ‘40’.
2. Ensure to use Procurement Type ‘F - External procurement’ along with Spl Proc Type ‘40’ in the ‘MRP 2’ View of the dependent plant in material master. Procurement type defines how the material is procured. The following procurements types are possible: o The material is produced in-house. o The material is procured externally. o The material can be both produced in-house and procured externally. The procurement type can also be defaulted during material master creation based on the configuration of material type as highlighted below:
We use special procurement when we want to be able to override the procurement type in the material master or define the procurement type more precisely. If the procurement type is in-house, you can nevertheless force the system to ignore the BOM and routing, and process the material as if it were externally procured, by specifying the special procurement as external. Eg. Material has Procurement Type ‘F’ to indicate external purchasing, with Spl Proc Type ‘40’ indicating the special procurement type is Stock transfer (proc.from alter.plant).
3. Set the document type for the generation of ST PRs.
The document type of auto-generated ST PRs can be defaulted with the use of MRP Group. Goto the following path to set the document type for the Plant & MRP Group combination: SPRO Material Management Consumption-Based Planning Planning Procurement proposals Define External Procurement
Click on the MRP Group and define the DocType ST for the ST PRs.
DocType SPO Standard PRs DocType SC Subcontracting PRs DocType ST Stock Transfer PRs
Since we are working on Stock Transfer PRs, set the required DocType under the column DocType ST. Eg. DocType ST ‘ZEC’.
The MRP Group should be assigned to the Material for which ST PRs needs to be generated in the material master under MRP 1 View.
4. Allow PR Doc Type to have Item Category ‘U’ in the configuration
Ensure that the DocType ST used necessarily allows the Item Category ‘U’ in the configuration. SPRO Material Management Purchasing Purchase Requisition Define Document Types
5. Create Parent Plant as a Vendor using Plant Account group
Eg. Created Parent Plant 1001 as vendor V1001 with a custom Plant Account group Z004. Standard Account group for Plants is 0007.
6. Start the Planning run You can plan for all the materials in a Plant by running Planning run via Transaction MD01, but only for those materials with above settings a ST PR can be raised to satisfy requirements. Eg. Planning run for a single material ‘Test Material’ under dependent Plant 1000 to verify the generation of ST PRs to satisfy the needs of the dependent plant 1000 via parent plant 1001.
Once the Planning run is completed for the material, the results are displayed as below.
Eg. ST PR# 10000020 was generated successfully.
