Cannot set Returns flag in Purchase order/return flag greyed out

[floydausten]

Good afternoon all,

I am trying to run the returns process.

I have booked a 122 movement on the original material document, which move the stock from Blocked stock to On-order stock and a purchase order was automatically created.

However, when I enter the purchase order, I see that the Returns flag is not set and that I cannot set it manually, because the checkbox is greyed out.

What is causing this and how can I solve it?

Kind regards,

Floyd
