Hi All,
I am trying to import actuals using GL mapping into a P&L module ( Target).
The issue is some GL codes map to both COS as well as OH's.
The source module is dimension-ed per below:

One of the stations is a dummy airport and holds all overhead costs. So for example, GL 01 relating to expense A is imported correctly for all airports with the exception of the dummy. Expense A if present in dummy location should be using an alternate mapping to redirect the costs to COS.
Mapping module is dimension-ed per below

Target module

Thanks for your inputs.
