Hi,
S_ALR_87013623 is a report painter report based on reporting table CCSS. CCSS contains the field FKBER (you can see this in SE11). Now (not sure about that), if the CCSS records contain the FKBER information (not only the field is there but it is filled with the FKBER information), copy the report painter report to a "Z" report, enter FKBER as a selection field (or whatever you need) and see if it fulfills your requirement.
