Remove filtre from delta infopackage

Hi Experts ,

I would like to remove the data selection ( FISCPER) from the delta infopackge of the extractor 0FI_GL_4 ( based on AEDAT) .

There is a risk to losse data if i break the init and rebuild the delta without data transfer ?

Otherwise ,there is a possibility to remove this data selection from the delta infopackage without rebuilding the init ?

Thank you so much for your help .
