SAP Error Message - Details

• Message type: E = Error

• Message number: 630

• Message text: Automatic purchase order generation for movement type &1 is not allowed

What causes this issue?

A goods receipt is to be posted without a reference to a purchase
order. A purchase order is also to be created automatically in the
background. The Customizing settings for the relevant movement category
&V1& do not allow purchase orders for material &V2& to be generated in
the background.
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.
&System_Response&
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
and it is supplied with values from the goods receipt interface.
