We just create a change request for an InfoSouce. Now we transport this change request from DEV system to TEST system. But when this change request was imported on TEST system, got the "Method Execution" red error which can be checked through STMS in log. The red error msg is "Source system A does not exist", where A is our R3 DEV server. Actually we need the source system B which is R3 TEST server in the InfoSouce transported into BW TEST system, but the problem is that the change request was created on BW DEV which uses A as Souce System in the InfoSouce, then how to make the InfoSouce has B on BW TEST after the transport?
