Hi,

My requirement is to catch the warning raised by Acumatica on the Purchase Order Screen for Order Total field. If there is a warning message regarding budget exceeded, I need to convert it to an error and stop the Release From Hold Action.

I implemented the code but it works only one time the button is clicked, the next time the button is clicked, since the warnings from Acumatica are gone, the code does not work.

Steps:

1. On Page load, there is a warning on the field Order total (The project budget is exceeded. For details, check warnings in the document lines.)
2. Click Release from Hold button, error message is shown and the field is highlighted - Working as expected. Warning messages are lost because I raised exception.
3. Click Release from Hold again, I am able to proceed since the Acumatica Warnings are not there after step 2.

Is it possible to retain the warnings as well as shown a message to the user at same time?
