MRC Target Segment is different than the offset segment and receiving an error...HELP!!

Hi,

The requirement is as follows;

All Company- All Accounts-All Cost Centers-79-All Intercompany accounts

CAPA.ACCCTS.COST.79.INTER * 25/100

CAPA.ACCTS.COST.11.CCOST (target)

CAPA.ACCTS.COST.79.INTER (offset)

The issue at hand is the client wants tthe target to not only be a different business segment (11, and that is fine) but also intercompany account CCOST (which is a valid CHILD value for Corporate Costs). I continue to receieve an error..Do I need to SUM the Interco segment?

Can this actually be done?

Please advise and thank you!!
