Hi Irmihild,
I was able to display the static filters in Analysis workbook that were set in the Bex query.
To display the name of the dimension for which a filter has been applied:
=SAPGetDimensionInfo("DS_1","0COMP_CODE","Name")
To display the value of the filter applied:
=SAPGetDimensionStaticFilter("DS_1","0COMP_CODE","TEXT")
you could display as "TEXT" or "KEY" or INPUT STRING
Similarly you could use other SAP functions like SAPGetDImensionDynamicFilters or SAPListOf StaticFilters (this will display all the static filters that were applied for that query.
I wasn't sure if this is what you were looking for but just wanted to share this information.
