AS02 asset managmt-> ANLA-GDLGRP allow any value

Hello,

I would like to allow any value in the field ANLA-GDLGRP in the asset management (AS02). But this table has a check table and in this way I must not set values that are not in the check table. Is there a way (but modification of the SAP standard) to change the behavior and allow any value?

Thanks a lot, Vanessa
