How initial master data is transferred to EWM from ERP?

New Material master data from ERP can be transferred to EWM automatically without any manual intervention using the Core interface (CIF).

To create a core interface  

T-code: CFM1- Create Core Interface Model

T-code: CFM2- Activate Core Interface Model

How to transfer the Customers and Vendors master to EWM?

Similar to Material Master, CIF can also be created for BPs using and selecting customers, and vendors.

Also, select the create LOC/BP option to create both BP as well as location data in the EWM system.

T-code: CFM1- Create CIF Model

T-code: CFM2- Activate CIF Model


How to display the CIF application log?

T-code: CFG1

How to Automatically transfer master data to the EWM system?

Background jobs can be scheduled for the below programs using Tcode SM36 and variants created for CFM1 can be used in the batch jobs to transfer data periodically.

How Delivery integration is done between ERP-EWM?

To distribute the deliveries, a distribution model is created beforehand. The model can be created by T-Code: /SPE/OL19

To check the result, we can use t-code BD64. Distribution models are required to be set up for the production system before Go-Live.

Below Function modules are used to process the deliveries

How to Pull expected goods receipt into EWM from ERP?

Use T-Code /SCWM/ERP_EGR_DELETE this reports calls /SCWM/ERP_DLV_DELETE and it deletes the existing EGRs and creates new ones.

How to Push EGR from the ERP system to EWM?

We can use T-Code /SPE/EGR this calls report /SCWM/ERP_EGR_CREATE and it will create EGRs in the EWM system.
