Unable to create Retro billing for Intercompany invoice document

Hello,

I have created a intercompany billing document (IV). Later I changed base price PR00. I was able to create retro billing document for external invoice to customer but when I am trying to create retro billing for IV then I am getting error that Ship To customer is missing in KNVV table but the Ship To is already maintained. All the required copy controls have also been maintained. Is there any specific config required to enable retro billing for IV documents?

Thanks,

Karan
