Intercompany sales third party FI entries

Hello all,

Can somone please tell me how do the FI enteris flow in case of Intercompany third party sales.

Here Customer XYZ places order on company code 1000 and then comany code 1000 order company code 2000 to directly deliver this material to the customer XYZ.

I think the FI entries that will be generated will be at the time of PGI and billing.

Please guide,

Thanks,

Sam
