Does someone uses free selections (FSL_*) to update a variant in SAP

I run an SAP job where I need to update a free selection by using the Parameter FSL_.

The parameter is updated correctly but the job does not use the variant which is called in the job but creates a temporary variant, nevertheless the parameter "TEMPORARY_VARIANT" is set to N(o).

The variant contains the free selection but is mainly empty. We downloaded the variante with the standard report SAP_ImportVariants into BPA. But during the prozess the variant is not updated with the values which are saved in the downloaded variant, only the free selection is set.

Does anybody has any experience with FSL_* parameter update and could run SAP jobs with a variant update of such an parameter?

Thanks for any hint.

Kind regards
