Allow only one production order in GI Document

Hello Experts,

We are using interface with external system for production order confirmation & GI. Sometimes due to lock issue the records are going to CO1P (CORUPROC) when we process these records using CORUPROC system is creating single GI Document for multiple production orders.

We have a requirement to allow only one Production order in GI document. It should not create single document for multiple production orders.

Can you please help to resolve this issue?

Thanks,
