How to transfer PO from ECC6.0 to SRM6.0 use standard IDOC?

Hi everyone,

I want to transfer PO from ECC6.0 to SRM6.0 use standard IDOC. Now in ECC client, the outbound IDOC is OK, but in SRM client, can't receive inbound IDOC. When I check IDOC states in WE02 in SRM, the T100 text is: basic IDOC type ORDERS01(also ORDERS*) does not exist.

How can I solve this problem? Could somebody kindly help me?

B.R. & Thank u very much!
