Separate calculation of 2 diferent plans wich uses same attributes

There are 2 compensation plans: A and B.  Each plan has its own elements and formulas. We need to get the calculation by separate way of each of them and finally summarize the result. Right now we are not getting that result.

Records with their attributes are populated by legacy interfaces (not from AR or OM) or entered manually at CN.  However one attribute could store different concepts depending the plan that it's expected to use it.

For example attribute49 means sales quantity for Plan A.   And attribute49 means a

reference number for Plan B - a reference attribute not used for calculation.
