Unalbe to block BP in GTS system in PRD

Dear All,

I am able to block the BP in GTS in QAS system. I am able to view them in blocked list also.

But I am unable to block the BP in GTS in PRD system.

When I am clicking the Block checkbox system accepts the blocking.

But when I am saving the same, the block disappears.

I am performing the blocking at -

/SAPSLL/MENU_LEGAL - SAP GTS Area Menu > SAP Compliance Management: Classification/Master Data

> Maintain Business Partners > BP number XXXXX [change organization] > SAP GTS tab page > SPL screening Status

> Block [Check box]

Please help.

Thanks & Regards
