One of our SAP box has just been migrated to S/4 HANA. Now, we are in the blueprinting stage wherein we are to integrate SAP ERP with the new S/4 HANA system.
I would like to seek for your advise on the important items that should be checked in the SAP SD/MM functional perspective to integrate the Customer master as well as the Material Master between the two system. Is there any existing BAPI/ALE that we can use to flow the data between the two systems?
In addition, the customer master would be created in SAP ECC while the Material master will be created in S/4 HANA.
Your detailed advise would be greatly appreciated.
