Hi Sasikanth
Yes I did a direct update in table EKPO using field ELIKZ same as NOn limit items although this field is not visible on PO screen in backend yes if you update this it will clear from POWL .
You can mark from SRM SC portal also that Final entry checkbox it comes from standard .
When this field gets updated in the backend via BBP_GET_STATUS2 it will also update SRM
Let me know if this helps ?
Regards
Vinita
