Hi Beejoy,
yes, the FI Payment documents also get screened synchronously against the SPL Data exist in the GTS System.
the process is same as Logistics, where the BP is not exist in GTS, the Customs Document would be in Technical Incomplete and if the BP is matching with SPL Data then the document get blocked until the relevant compliance team verify whether the block is true hit or false hit and then they release the blocked BP to proceed for further process of Payment Proposal.
hope you understood, if you still have any clarifications please let me know.
Thanks,
