Can we edit wrongly entered already approved item receipt in PO without deleting?

yes

Thanks Mars. I tried to edit but received field is disabled. How can I edit it ?

role?

I have system Admin Role.

is there no edit button in item receipt record?

There is edit button however the received field is greyed out. Is there a way out ? They were suppose to receive 1500 but received 2500 . So now need to edit it.

is it a new item receipt or an item receipt in a previous or closed period?

It's the new purchase order and item is wrongly received. When I try to edit I can't. But I am required to correct it. And it is approved by supervisor/pending bill. So looking for solution

Default behavior is admin role should be able to edit it. If you can share a screenshot of the “greyed out received field”, it may shed more light on your question. If I have to guess on a resolution, you could try cancelling the active workflow as it may have a custom action that sets the display type of the received field to “disabled”.

Thank you Mars. I tried all possible solutions, May be I am missing something here. I just joined this company and so many scripts running in background. So Instead of deleting it, I suggested to fix it by doing Inventory Adjustment.
