Urgent plz!! partner profit centre derivation

Question

my company has 2 plants under one company code . one plant supplies one material type A to second plant .Both the plant have different profit centres.
How to make the partner profit centre hit when i am doing an invoice posting in MIRO.
I tried doing a derivation rule in 8kes , but the partner profit centre has to hit after matching the particular material no and the plant no .
in the enhancement source text there is no field for plant where i could modify the source text .
Moreover at the user exit in 8kes , after creating a breakpoint , it is not getting hit during MIRO .
Plz help

Hi Sunil ,
                This is very much possible .
Procedure :-
generate the report ex fbl1n with any criterea.Before that check weather field profit center is there in Dynamic selections .
Even after giving if it is not coming .then go to settings in fbl1n report and there click on special fields .
New entries
Table Name BSIS/BSID/BSIK
Field Name  PRCTR
Similarly  
Table name  BSEG
Field Name  PRCTR
you save the changes
if you find any error like field prctr already exist then no need to craete firld PRCTR for BSIS  but you need to create it for BSEG (form which these figures populate )
then save .
CAUTION: ypou may not find the changes until indexing takes place .
so Wait fro some time for ex In some comanies indexing takes at night time . after that only you can see the changes .
this way you can add some special fields .
Hope this will cater.
Thqanks and Regards,
Sunil
