Unable to use Functions-Create Credit Note for a PO which is Invoiced


I have an issue while i try to create credit note from any PO.

Let us take a PO which is invoice updated, i selec teh PO and click on Functions- Create Credit note (from teh Header area) and i get the screen where we have all the POs for this vendor, but I am unable to tick neither in the header area nor in the details area.

i created a new vendor and a new item and created a new PO and invoiced it then i treid to create the Credit note, but no luck.

Any idea?



What is the safety level of Invoiced Order in AP parameters(update tab)?

If locked chage it to None/Warning.

Your safety level for invoiced orders is set to “Locked”.
