Intercompany Service Purchase cost to seperate GL account

Dear Experts,

I am looking for a solution to post service cost during MIGO to be posted to two different accounts based on the vendor.

All purchases from group company vendors (Trading partner active) should post to "Subcontracting - From Group"

All purchases from external vendors "Subcontracting - External"

Is there any setting in OBYC or FI substitution to acheive this.

Thanks & Regards

Raghu
