This note describes how the special features of repetitive manufacturing are to be taken into account in the integration with Extended Warehouse Management (EWM). Other terms
You enter a confirmation for repetitive manufacturing in the ERP system; for example, via transaction MFBF using the physical data. If the receiving storage location is managed in EWM, the system creates an inbound delivery instead of posting the goods receipt directly. The inbound delivery is distributed to the EWM system where the goods receipt is posted and the material is put away.
MFBF, MFHU, MF42N, /SCWM/DLV_PRODUCTION_REP_MAN Reason and Prerequisites
The following delivery processing steps (which are generally possible in EWM) are not supported by repetitive manufacturing in the ERP system:
- Partial goods receipts; for example, when confirming the warehouse task in the putaway process
- Changing the delivery quantity
- Manually creating the inbound delivery
- Backflushing from an EWM storage location
The EWM system provides processes with which difference processes are executed without changes to the quantity in the inbound deliveries and without splits. The document types and item types required for the delivery are included in the BC set /SCWM/DLV_PRODUCTION_REP_MAN. The exact procedure is explained below. Solution
In classic repetitive manufacturing, the goods issue and the backflush are posted in a logical unit of work (LUW). As a result, the system reduces the planned order and its dependent requirements. For this reason, the stock and the requirements situation are linked from the point of view of the planned order.
If you post the goods receipt for repetitive manufacturing to an EWM-managed storage location, an inbound delivery is generated. The goods issues of the component are flagged instead of posted in ERP. If the goods receipt is posted in EWM, the system sends a goods receipt message to the ERP system. If the ERP system processes the message and updates the goods receipt for the inbound delivery, it processes the flagged goods issues. They are updated together with the goods receipt in an LUW so that the system adjusts the planned order and its dependent requirements simultaneously.
To prevent users in the EWM system from carrying out work steps that cannot be processed in repetitive processing, SAP recommends that you proceed as follows:
Post the goods receipt with reference to the delivery. Proceed as follows:
- Post the goods receipt with transaction /SCWM/PRDI before you carry out further work steps.
- Use the PPF action /SCWM/PRD_IN_POST_GR_ON_SAVE to post the goods receipt directly when you create the inbound delivery. The action is available in the action profile /SCWM/PRD_IN_RM, which is assigned to the document type IRM that is delivered by SAP. To do this, maintain the following data record for PPF (SAP Easy Access from Extended Warehouse Management -> Delivery Processing -> Actions -> Maintain Condition Records for PPF Schedule Conditions). Enter a condition record for the application DPP, maintenance 0_RPMA with
Prohibit quantity changes and delivery splits by using the settings in the process code profile for the inbound delivery item. Use a process code profile that only allows I003 (difference supplier, no adjustment) and I007 (adjustment to quantity 0) in addition to the mandatory process codes. The BC set /SCWM/DLV_INBOUND_PROD_RM_PROF (included in /SCWM/DLV_PRODUCTION_REP_MAN) provides the profile /SCWM/INB_PRD_DLV_REM for this.
Prohibit the manual creation of the inbound delivery or items in EWM via the process control profile.
If a user determines quantity differences when processing the inbound delivery in EWM, the difference has to be posted as charges for warehouse.
To clear actual difference, cancel the confirmation for repetitive manufacturing in ERP or enter a correction for the confirmation. The system then creates an outbound delivery in the ERP system. When you replicate the outbound delivery, the EWM system creates a correction delivery. In EWM, post the goods issue for the correction delivery. Afterwards you can use the Difference Analyzer (/SCWM/DIFF_ANALYZER) to compare the quantities from the differences and the correction deliveries with each other and post them.
SAP provides Customizing settings that are aligned with the requirements of repetitive manufacturing with the BC set /SCWM/DLV_PRODUCTION_REP_MAN.
