Query filter dosn't work with input variable

Hi all,

I have a query and in a filter i have value ( FV270, FV270) for characteristic (ZINVESTYP).

And i have manual input variable (VAR_INVESTYP_S1) for this characteristic.

When user opened the query and selected value from list, filter in the query is work fine.

But when a user sets the out filter value manually then filter doesn't work

and template opens for input - it's not correct.

Why the filter does't work and template opens for input? How to make the filter worked?

Please help to solve the problem.

P.S. we have BW 7.0
