How to Remove billing docs list from VF04 for STO process ??

Hi experts,

We have implemented stock transfer process between our two plants at different locations.

The delivery documents are created using tcode : VL10B from Purchase orders.

These delivery documents are present in the VF04 billing due list.

Now after we create Billing documents(Pro forma/Excise invoices) from these Delivery documents, they still appear in VF04 billing due list.

So kindly suggest what configurations to be done in order to remove these Delivery documents from VF04 list.

Thanks,

Vishal
