Hi Firdosh,

Short answer, no.

If I understand correctly, the PR was used to obtain a material or labor activity from a vendor for the service order that is now invoiced.

Unfortunately at this point it would not be possible to change the vendor or the purchase requisition. You indicated receiving the product/service for a cost from a specific vendor whereas another vendor *may* have a different cost and logistics might have been based on the origin of the product meaning the vendor may not even be from the same country thus having different costings (think currency for example).

This is why there is an approval process that should be followed before executing/receiving the PR for fulfillment of the demand.

Changing would also fail the three way matching if you were using this functionality too as you would have already indicated receiving from vendor A so invoicing is completed 

Hello @Phil Seifert ,

Thank you so much for your quick and in detail response.
