&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.

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.

• What is the cause and solution for SAP error message WP630 - Automatic purchase order generation for movement type &1 is not allowed ?

  SAP Error Message:
  
  WP630 - Automatic purchase order generation for movement type &1 is not allowed
  
  Cause:
  This error occurs when you try to perform a goods movement with a movement type for which automatic purchase order (PO) generation is not configured or allowed in the system. In other words, the system is set up such that for the specific movement type (e.g., 101, 261, 501, etc.), automatic PO creation is either not possible or not permitted.
  Typically, this happens in scenarios like:
  
  Using a movement type that does not support automatic PO generation.
  The configuration for automatic PO generation for that movement type is missing or incomplete.
  Attempting to trigger automatic PO generation in a process where it is not designed to work (e.g., certain stock transfers or consumption postings).
  
  
  Explanation:
  In SAP Materials Management (MM), automatic purchase order generation is often linked to specific movement types, especially in scenarios like subcontracting or special procurement. The system checks the movement type to decide whether it should create a PO automatically.
  If the movement type is not maintained in the configuration for automatic PO generation, the system throws this error.
  
  Solution:
  
  
  Check Movement Type Configuration:
  
  Go to transaction OMJJ (or SPRO path:
  
  Materials Management -> Inventory Management and Physical Inventory -> Movement Types -> Copy, Change Movement Types).
  Verify the movement type you are using.
  Check if automatic PO generation is allowed or configured for this movement type.
  
  
  
  Maintain Automatic PO Generation Settings:
  
  Use transaction OMI4 (or SPRO path:
  
  Materials Management -> Purchasing -> Purchase Order -> Automatic Purchase Order Generation).
  Here, you can maintain the settings for automatic PO generation for specific movement types.
  Ensure that the movement type in question is assigned correctly for automatic PO generation.
  
  
  
  Check Special Procurement Key:
  
  Sometimes, automatic PO generation is linked to the special procurement key in the material master or info record.
  Verify if the special procurement key and movement type combination supports automatic PO generation.
  
  
  
  Review Business Process:
  
  Confirm that the business process you are trying to execute supports automatic PO generation.
  For example, automatic PO generation is common in subcontracting (movement type 541/101), but not for all movement types.
