AR Transaction type mapping to OM Transaction type

Hi All,

Please help me defining AR Transaction Types for the below scenarios.

In our business, we have requirements to track business of domestic, export and intercompany.So we have defined 3 Order types in Order Management with the namings such as above.

We also have a requirement to capture what kind of Sales Order that we process.Based on this we have defined some OM Line Types such as Parts,Assembly,Repair etc.

Now to map these OM setup, from Receivables we have defined 3 Transaction Types such as Inv Domestic,Inv Expo and Inv interco which are linked at OM Transactype definition.
