3652757 - Error message "enter fixed vendor" persists in "my purchase requisition" app (F1643A) despite vendor assignment

• The error message "Enter Fixed Vendor" persists in the "My Purchase Requisition" app (F1643A) even after assigning a fixed vendor.
• The app allows saving the purchase requisition despite the error message.
• The error message creates confusion and delays in processing.

1. Open the "My Purchase Requisitions" app (F1643A).
2. Enter required data except for the fixed vendor.
3. Observe the error message "Enter Fixed Vendor."
4. Assign the fixed vendor (e.g., 10000001) and click "Apply."
5. Notice that the error message does not clear.
6. Click "Order" to save the purchase requisition.

• After assigning the fixed supplier from the Source of Supply facet, a merge call updates the backend data and performs validation.
• However, the latest validation messages are not sent to the UI because no "GET ITEM" call is triggered from the UI.

1. Perform a hard refresh of the page after assigning the fixed vendor to clear the error message.
2. Alternatively, change any data on the UI that has side effects configured, navigate to another item and return, or refresh the page to trigger a "GET ITEM" call and update the validation messages in the UI.
3. An enhancement is planned for the CE2602 release to automatically trigger a "GET ITEM" call upon vendor assignment, ensuring validation messages are updated in the UI.
