what happen if idoc extension will be changed ?

HI,

we are using a BPM (a big one) with a Multimapping zMATMAS03(Source) & RFC(Source) to MATMAS05(Target).

The source(zMATMAS03) IDoc has a extension(German Erweiterung) with new Segment ZZxxx and new Fields ZZyyy.

What happen if the allready importet and mapped zmatmas03 Idoc will be changed in the source system ?

Example. We added 2 new Fields in the old zzxxx segment.

Did i have to map everything new if i import the new idoc ? or did the new field are added to the old idoc and the mapping is working again ?

Regards,

Gordon
