EVCVW filter certain members?

Hi,

I'm using BPC MS 7.5.108.02 and I've recently tried to write an EVCVW formula that enables me to filter exactly two values.

The first value is in K5, with the formula =EVPRO("BIS";"BottomUp";"Planjahr1")&".DEC", resulting in 2013.DEC

the second value is in K6 with the formula =EVDES(EVPRO("BIS";"BottomUp";"Ausgangsjahr");"BIS")&".DEC", resulting in 2012.DEC

My EVCVW formula is =EVCVW("BIS";"Planungsjahr";K5:K6)

Unfortunately, this doesn't work. When I double-click the ECVCW, it says that my filters format is invalid, and then it doesn't filter the values.

How can I do this, that I get the filter to the two values found in K5 and K6?

Yours,

Peter
