Error: Document has been modified after you have opened it

Issue: Error: Document has been modified after you have opened it (2025-03-28 18:36:45.100742, 2025-03-28 18:37:35.351973). Please refresh to get the latest document.

Normally happens when you have multiple windows open of the same doc , the one instance of the doc is edited , so when you revert back to the other instance of the doc the system will notify you that the document has been modified and you would need to refresh…

Proposed Solution:

Assume the error displaying in POS Awesome, then only open one tab with POS Awesome, don't open it with multiple tabs or keep sales invoice screen opened with it esp in multiple window with POS Awesome multiple times.
