Payment Document Screening for SPL

Hi Guys

I am facing some issues in doing Synchronous payment document screening in GTS.

1) Is there anyway to recheck financial documents - Same which we do for Logistics documents via /sapsll/cuhd_mr_spl

2) Is synchronous checks possible? Like the Purchasing docments where system will let you know as soon as you create a PO.

While i am checking the Log its showing unable to determine active Legal regulations, this is only being shown for Payment documents.

The scenario here is we create proposals and instantly do a Payment run, so synchronous check is very essential for us.

Thanks

Carl
