Issue with "WHEN-NEW-BLOCK-INSTANCE" trigger on AP_APXINWKB form

Hi,

The trigger event "WHEN-NEW-BLOCK-INSTANCE" is not working on AP_APXINWKB form.

Requirement : Restrict Invoices on the basis of the Supplier Site {Segment1 of liability account at supplier site}. We have tried below simple query to check if the trigger event is working. Even though the trigger condition fails, we are able to query the invoices. Trigger event is not working as per the expectation.

Please find the below details:

Form : AP_APXINWKB

Trigger Event : WHEN-NEW-BLOCK-INSTANCE

Trigger Object : INV_SUM_FOLDER

Condition:  :INV_SUM_FOLDER.VENDOR_ID in (1)

Processing Mode: Both

Thanks,
