Hi,
It looks like you are trying to use the EPMDimensionOverride() function in the same way that the EVDRE() used to expand. This will not work exactly the same and you need to think a little out of the box by using the properties in your dimension.
Try the following 1) For BAS rather use CALC=N 2) For SELF, just point it at the cell that contains the member you are working with or use the EPMContextMember() 3) Your last selection should still work.
Cheers,
A
