Cannot create billing document from sales document
i am trying to create billing document from the created sales document.
But the billing document is not generated. I was getting the error - ' Document is blocked from billing'.
SO, i changed the billing block and left it blank, and when I tried to create the document again, I got another error " Create billing document" not allowed (uSER STATUS ST01, Object VB006000071200000).
Please help me out,
