I wonder if there is BI content datasource for loading infoobject 0USERNAME? I need to update attribute 0BPartner. I am having troubles with uploading data via 2LIS_02_SCL and 2LIS_02_ITM (both BI content) and I am getting error: "No value found for attribute 0REQESTER for InfoObject 0USERNAME". There is a routine in both of these transfer rules updating field 0REQUESTER from data of infoobject 0USERNAME. I expected that BI content would work with no additional development needed ...
