Error when multiple DTP's created for the same Infoobject
I have created a Custom Info object Z_IUCPOD which is a Master data Attribute. Data has to be loaded from 4 data sources into this Info Object hence I am trying to create a DTP for each datasource. The first one is created successfully but when I create and activate the second DTP to the same Infoobject from the second Datasource it throws an error - UNCAUGHT_EXCEPTION 9CX_RSR_X_MESSAGE)
I need your help to resolve this. Please correct me if I am doing it the wrong way. Immediate help appreciated.
