SAP Error Message - Details

• Message type: E = Error

• Message class: VL -

• Message number: 878

• Message text: # error messages due to non-availability (message VL 150)

Number of error messages due to non-availability
For all materials, the system counts how often error message VL150 is
issued. This error message is issued when the material of the quantity
that has been confirmed in the order is not available during delivery
creation.
Causes
1. Availability checking rule in the order is not as comprehensive as
in the delivery (e.g. with purchase requisitions in the order, no
purchase requisitions in the delivery)
2. Regarding the material, there are orders in which no requirements
are transmitted. If these orders are delivered, they may take away
confirmed quantities from other orders under certain circumstances.
3. In Materials Management, withdrawals have taken place (e.g.
scrapping, inventory difference...)

How to fix this error?

1. Check which reasons apply and, if necessary, correct it.
2. Rescheduling, if necessary (only if 'Quantity/Date' is not fixed in
the order). Note during rescheduling that the program is a long-running
transaction and should only be carried out as a background job.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

  The SAP error message VL878, which is related to the non-availability of stock, typically occurs during the process of creating or processing outbound deliveries. This error is often accompanied by message VL150, which indicates that there is no stock available for the requested delivery.
  Cause of VL878 and VL150
  
  
  Stock Availability: The primary cause of this error is that the system cannot find sufficient stock in the specified storage location or plant to fulfill the delivery request. This could be due to:
  
  Stock being reserved for other deliveries or orders.
  Stock being in a different location or plant.
  Stock being blocked or in a status that prevents it from being used (e.g., quality inspection).
  
  
  
  Incorrect Delivery Date: If the delivery date is set in the past or if the stock is not available until a future date, this can also trigger the error.
  
  
  Configuration Issues: There may be configuration issues in the material master or in the settings for the delivery process that affect stock availability.
  
  
  Inventory Management Issues: Problems with inventory management, such as incorrect stock counts or discrepancies between physical stock and system stock, can lead to this error.

  Check Stock Levels: Verify the stock levels in the relevant storage location or plant. You can do this using transaction codes like MMBE (Stock Overview) to see if there is available stock for the material.
  
  
  Adjust Delivery Date: If the delivery date is incorrect, adjust it to a date when stock is available.
  
  
  Review Reservations: Check if there are any reservations or allocations that are preventing the stock from being available for the delivery. You can use transaction code MB22 to view and manage reservations.
  
  
  Check Material Status: Ensure that the material is not blocked or in a status that prevents it from being used. You can check the material status in the material master record.
