What causes this issue?

In an SQL view that allows write access to its base table, both
buffering and replacement object are defined. These are not possible
together since otherwise, during database accesses that read using the
table buffer (RSQL), you could get incorrect invalidation of the buffer
and, consequently, incorrect data as well.

The view can only either be buffered or given a replacement object.

• What is the cause and solution for SAP error message MC826 - Buffering and replacement object cannot be used simultaneously ?

  The SAP error message MC826 ("Buffering and replacement object cannot be used simultaneously") typically occurs in the context of Material Management (MM) or Production Planning (PP) modules when there is a conflict between the buffering settings and the use of a replacement object in a material master record.
  Cause:
  This error arises when:
  
  Buffering Settings: The material is set to be buffered in the system, which means that the system is trying to optimize access to the data by storing it in memory.
  Replacement Object: A replacement object is defined for the material, which is intended to be used in certain scenarios (e.g., when the original material is not available).
  Conflict: The system does not allow both buffering and the use of a replacement object at the same time, leading to this error.
  
  Solution:
  To resolve the MC826 error, you can take the following steps:
  
  
  Check Material Master Settings:
  
  Go to the material master record (transaction code MM03).
  Check the "Basic Data" and "Sales" views for the material in question.
  Look for the buffering settings (usually found in the "MRP" or "Sales" views).
  
  
  
  Adjust Buffering Settings:
  
  If the material is set to be buffered, consider changing the buffering setting to "No Buffering" or "Buffering Not Allowed" if the replacement object is necessary.
  You can change the buffering settings in the material master using transaction code MM02.
  
  
  
  Review Replacement Object:
  
  If the replacement object is not needed, consider removing it from the material master.
  If it is needed, ensure that the buffering setting is adjusted accordingly.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to material master data management for more details on buffering and replacement objects.
  
  
  
  Testing:
  
  After making the necessary changes, test the transaction that triggered the error to ensure that it has been resolved.
