Pricing condition - not posting into different GL Account

Hi All

I have created a third party scenario where sales order is created and converted into PO automatically. In this process we don't have a GR (MIGO) but we have only a Invoice (MIRO) posting. I need help from you that for every item- quantity I have to add a SERVICE FEE on the NET price and should get posted to another GL account while doing the invoice (MIRO) only.

I have done the below settings; copied frieght quantity

m/08 - Pricing

m/06 - Condition type

Transaction Event - ZCN created

OBYC -

PO conditions

But after doing the MIRO the service Fee is not getting posted in different GL account.

Can you please help me out what went wrong in this configuration.

Is MIGO mandatory for posting into different GL account and then we have to do the MIRO?

Regards
