Data_Provider_Filter with Planning Function

Hi, Everybody.

I create Planning Function for copying from source version to target version.

Planning Function is fine.

But my user ask me to filter the data before copy.

So, I create the data provider and filter the source version and add data_provider_filter = my_data_provider to the button.

When I press button for copy, the pop-up message show "Value of characteristic 0VERSION: AB1 is not included in the selection".

**AB1 is the target version.

Why the data provider filter have the both of source version and target version?

Thank you
