Updating IC PO after SO Linked

Hello,

We are using Intercompany PO. Will explain our scenario. Once PO is linked with SO. We later need to change some record in IC PO so we use ‘Remove PO Link’ in SO. It unlinked the PO. Then we unapprove the PO and make some changes and approve it back. But now issue is that it is created new SO number.
I need to know how we can retain the same SO number even though its unlinked earlier. Is there any other alternate way so achieve same SO number once updating the record in PO.

I was told, you really never want to break the link. If you do, you’re completely manual and assume responsibility for all processes downstream.

You should make the change on your PO and follow it through the system again on the sales side.
