How about the following:
Assuming you have 2 characteristics (Plant and Parent company) and 1 KF (Net Sales).
Now let's create a projection with Filter using Input parameter on Parent company (with user input value as ABC), which might give the output as:
| Plant | comp | Net Sales |
| P1 | ABC | 10 |
| P2 | ABC | 5 |
Now, let's create a second projection with the Calc KF "Net Sales calculated" with the formula as:
if comp = $input_value$, then 0 else Net_Sales.. this way you can simulate the EXCLUDE functionality.
| Plant | comp | Net sales |
| P1 | ABC | 0 |
| P1 | BCD | 15 |
| P2 | ABC | 0 |
Now union both the projections with two diff KFs, Net Sales and Net Sales Calculated.
| Plant | Net Sales | Net Sales Calc |
| P1 | 10 | 15 |
| P2 | 5 | 0 |
Subsequent model depends on your reporting drilldown requirement. If you drilldown Parent company also in the rows, then you will see the split in the values.
Please try this and let us know if it works or what other issues come up.. we can try resolving the issues..
