How to Add BAPI to Distribution Model and do the filtering and changepointe

Hi,

I am adding message type PROJECT to my distribution model while adding this message type PROJECT to my distribution model I am getting an error" Message type PROJECT belongs to BAPI Work breakdownstruct,Savereplica: USE the BAPI in model".

Now I use ADD BAPI method by using WorkBreakdownStruct and SaveReplica and add this to my distribution model.

Now I want to do the filtering at Company code level but in the filtering group controlling area and project profile is available.

i want company code also at that place.And also I have to activate the change pointers for message type PROJECT.

Please sugguest.

Regards,

Mani Kumar..
