Intercompany contract between 2 LE in same BU. How to create ic transactions?

Summary:

I have created an intercompany contract for a legal entity where provider BU is the same as receiver BU. In the contract I have specified the receiver project in the Billing line tab and Associated Projects line tab. There is no option to assign or add the providing project. I created a miscellaneous cost batch using projects within the same business unit. How do I create the project cost batch to create intercompany transactons?
