Invoice Splitting in VF06 due to payment reference document

Hi Experts,

Invoice is splitting based on payment reference document for some cases in VF06.

Payment reference document is actually the invoice number only and is generated at runtime.

The issue does not happen with VF04 for the same set of invoice documents.

I have searched the forum but could not find something that relates to my scenario. Can someone help me if they have faced similiar issue or any suggestions on the same.

Thanks and regards
