Asset PO from PR - Cost Center getting cleared when Asset is entered in PO
I'm having below issue. I have searched in the forum but could not find any solution.
Asset PR is created with cost center (same as linked in Asset >> time dependent) and G/L account.
When we try to create PO using PR, once asset number is entered, the cost center is getting cleared off/removed automatically.
My question is that is this a standard behavior of system or any correction required. Also can you please guide me where I can find the settings for above case.
