The problem that occurred could have been caused by the following:
The goods receipt is actually linked to a purchase order - there is no
reference document accompanying it.
An incorrect movement category was used.
The movement category you have used has incorrect Customizing settings.

You can post the goods receipt using the following transaction. While
doing this, you can change, for example, the movement category or enter
the correct reference document.
The transaction is started automatically after this information screen
