Manage Purchasing Value Sets - Table Validation - DFF

I have a validation set code with validation type 'Table'.

It allows me to get some specific data for my DFF (costCenter).

But we've got a new need from the client where we need to filter based on a DFF value that's specified in the Manage Location page ( we do the link with default location id in the requester preference in RSSP)

I added this part in my clause where, but it's not working :
From : GL_LEDGERS l ,FND_KF_SEGMENT_INSTANCES B ,FND_KF_STR_INSTANCES_B SI ,FND_KF_SEGMENTS_B SG ,FND_VS_VALUES_VL v ,FUN_ALL_BUSINESS_UNITS_V bu
