Integration of Extended Warehouse Management into PP
You can use SAP EWM in conjunction with the following PP application components:
Production Orders
Process Orders
Repetitive Manufacturing
Kanban
There are few important integration points to generate an PMR in EWM with Production Order.
1. Define Production Staging Areas in ERP System ( PK05)
Define new Production Staging Areas (PSA) in ERP. In general these PSA will be equivalent to the number of Work centers defined to perform the production process. The storage location
e.g.
2. Replicate these PSA to EWM ( In case it is decentralized EWM) - (CFM1)
Use CFM1 tcode for Transferring the PSA from ERP to EWM ( in case it is an decentralized EWM).
The same will be available in /SCWM/PSASTAGE in EWM where we assign a new PSA - Bins for each work center in EWM along with other paramerters like WPT, Staging Method Type.
3. Maintaining EWM Control Cycle ( LPK1).
With the EWM control cycle, you specify the EWM-managed storage location from which the material required for production is to be withdrawn and the production supply area in which this material is to be staged. In addition, you specify the staging type.
The following control cycle categories are possible in conjunction with SAP-EWM:
Control cycle for EWM
This Control Cycle Category
indicates that the source and destination that you specify in the control cycle are EWM-managed. You can use this control cycle category for production and process orders only.
In SAP EWM Advanced Production Integration, Staging and Consumption are two different steps for Production Planning Integration.
- Staging and Consumption by Production orders.
Staging and Consumption for production is performed on the basis of a production material request (PMR) in SAP EWM.
The PMR is created during WM material staging in SAP ERP and sent to SAP EWM. It represents the manufacturing order in SAP EWM.
4. Configuring ERP Integration for Production Material Request Processing.
4.1 Mapping of ERP Order Types to SAP EWM Document Type for Production
In Customizing for SAP EWM choose Extended Warehouse Management -> Interfaces -> ERP Integration -> Production -> Map Sap ERP Order Type to SAP EWM Document Type
4.2 Define a Product Group Type and Product Group ( Optional)
In Customizing for SAP EWM choose SCM Basis -> Master Data -> Product -> Product Groups -> Define Product Group Types
In Customizing for SAP EWM choose SCM Basis -> Master Data -> Product -> Product Groups -> Define Product Groups
Mapping of ERP Order Type to SAP EWM Item Type for Production
In Customizing for SAP EWM choose Extended Warehouse Management -> Interfaces -> ERP Integration -> Production -> Map Sap ERP Order Type to SAP EWM Document Type
Trouble Shootings and Checks.
- Upon releasing the Production Order, delivery is not created.
- Check the Plant and Sloc Combination in Production Order.
- Check the Work center and Staging Area linkage in ERP
- Check if the components are maintained in both ERP and EWM.
- Check the distribution model activation status in ERP<=>EWM Integration.
- Upon releasing the Production Order delivery is created but struck in Queue.
- Check ERP<--> EWM Document type Integration.
- Check ERP<--> EWM Item Type Integration.
- Check Goods Movement Bin determination for PMR.
- Check PMR Number Ranges.
hope this helps to understand Advanced Production Integration in detail.
