Issue in Intra Company Internal Settlement Document

Dear All,

I am creating Intra-company settlement scenario. For the same I am using Forwarding settlement document for intra company settlement.

Now my issue is in Internal Settlement Document, “Purchase organization number” is appearing in Sales organization field therefore system is giving error message that this organization is not a sales organization.

Also “Business partner of Sales org” is appearing in Bill to party Partner function field which as per my understanding should be Business Partner of Purchase Org.

Please suggest from where system picks the “Sales organization” and “Bill to Party Business partner” Values and how to resolve the same.

Regards,

Vibhu Gupta
