Hi,
"After saving the change, the CIF-interface is triggered and an update is sent to ECC, where this field is mapped into the MaterialMaster-data."
You mean this is working? You can trigger manually an update to be sent to ECC? Or this is your requirement? Because master data is NOT sent from EWM to ECC in the standard. And where would you want to map this field to? The PACI? Why that????? What would you want to do with it in ERP?
