variable hierarchy display not changed (BEx analyzer)

Hi

We have a BEx query, in which a drilldown characteristic is displayed as an hierarchy

Hierarchy display is active

Selected hierarchy:

Name - constant

Version - customer exit variable

Customer exit calculates version from manual input variable.

We need to view the report in BEx Analyzer.

When the query is opened, we select manual input variables and the hierarcy's version is set correctly.

The issue is that when we change manual input variables at runtime, the data is refreshed,

but hierarchy display is not changed. The selected hierarchy's version remains unchanged.

In order to change hierarchy display, we need to open characteristic properties and change the selected hierarchy manually

or we need to reopen the query and provide another manual input variables.

Our system version is 7.01 patch level 9

Is there any way to fix this problem

Or some workaroud?

Any help will be appreciated.

Thanks
