Issue with Form Personalization - WHEN NEW BLOCK INSTANCE at PO APPROVE

Issue with Form Personalization – Requisition Form (POXRQERQ) and Purchase Order Form

WHEN NEW BLOCK INSTANCE at PO APPROVE the logic should check the accounting string for a specific value and alert the user.

 

Intention: at “Approve” button a specific number in the charge account string should be checked and a text message should pop up.

 

Issue: it does not work after initial data entry + Save – accounting string pulled and  built - and first time press approve

First going into "Distribution" - then back to REQ or PO Form and then approve the message appears

Attached some screenshots? Any idea? Is there a timing conflict with the "account string generator"?
