Need update DISABLE_DATE in MRP_SR_RECEIPT_ORG

Hi,

We need to update the DISABLE_DATE field in MRP_SR_RECEIPT_ORG table of 2 thousand plus sourcing rules.  We plan to do this via back-end.  We are currently looking into updating it to a specific future date or to NULL (so that the sourcing rule will be effective until further update).

Will this not cause any conflict to any other table?  If not, can you please give the script for both scenarios (1. Update to 31-DEC-2011, 2. Update to NULL)?

Thank you very much in advance.

Anna
