Production order settlement without materials
I have a question that I am unable to find any solution :
We create a production order without materials using CO07 and everything is ok except that the cost is now sitting in cost element. Although the settlement parameter of the order goes to cost center, finance wants it to expense off to another GL account automatically. Status of prod order is REL PRC NMAT SETC. Settlement rule is created with cost center as one of the settlement receiver.
I went to t-code OBYC and found the PRD - General Modifications PRF pointing to the GL account I wanted.
I went to t-code FS00 (edit G/L account centrally) edit cost element, default acct assignment and was tempted to update the cost center to default the GL account to the cost center but was unsure what is the impact.
Is there anything else that i am missing here ?
Any help with t-codes guidance will be greatly appreciated
