Flat File IDOC -> ECC, segment defn x in IDoc type y CIM type do not exist

Hi,

I'm working on idoc flat file > sap scenario. Everything seems to be working up until the point where I get an error message:

EDISDEF: Port EDIPORT segment defn E2FINBU000 in IDoc type FIDCCP01 CIM type do not exist

I've loaded the meta data, and the file structure is fine. I believe the issue is related to PI not having the idoc I'm interested in listed in WE30. How do I reference the standard IDOC type FIDCCP01? Ideas I've had are around SWCV or transport from another system, the first I'm not sure which SWCV, the later seems a bit of a bodge and I dont like the idea.

Thanks

James.
