We setup "Create Billing Documents" Fiori app. When we try to create a Billing document from the list we are always getting the "Interval DI does not exist for object RV_BELEG" error in OData call. This is the only thing in SAP Gateway: Error Log. I checked SNRO for RV_BELEG . There is no entry for "DI". But I talked with functional team and they said they are not using anything like "DI". In GUI whole process works fine. They don't need this "DI" number range. Where is it comming from? Why only Fiori app is checking it? I am at a lost right now.
