Hi, you cannot prevent it from appearing by default, that’s a normal process. if your PO is approved, you must go through a Purchase Order change order to amend it, because it must go through the approval workflow again.

@Sanjay.K if you wanna disable the PO-CO process, then you need to change the below parameter at site level:

Hi @Sanjay.K,

without knowing which version of IFS you’re working with, the enforced use of Purchase Order Change Orders comes from the Site and/or the Supplier record.

Check the settings on those first?

Br,

This error appears when you try to make changes to a released PO while the enforce use of purchase order change order is turned on.

In order to avoid this error, turn off the toggle button under 'Enforce use of purchase order change orders' in relevant Site window> Sales and procurement section> Procurement tab.

Also, ensure to select the 'Use site default' option for PO change management field in relevant Supplier window> Purchase section> Purchase tab.

Thank you for all your prompt responses

I sorted the issue by changing the setting in supplier record
