Intercompany process using Idocs in SAP:

Automatic posting to vendor account is done by EDI. In our case where both companiesare processed in the same system (& client), it is sufficient to create Idec. This process requires several steps:1. Creating a Customer to represent the receiving Company.2. Creating a Vendor to represent the supplying company.3. Creating a Port4. Maintain an Output Type5. Creating a Logical Address6. Creating a Partner Profile for both Customer & Vendor7. The relevant MM customizing is maintained.8. The relevant FI customizing is maintained.

In our example we simulate intercompany sales between CC1040 and CC1070

Once the billing is released to accounting and IDoc Is created which posts an FI AP doc in the receiving company code:

Supplying Company Code: 1040Supplying Plant: 1040Supplying Sales Organization: 1040Supplying Distribution Channel: 99Supplying Division: 99Receiving Company Code: 1070Customer representing the receiving Company Code: IC1070
