• What is the cause and solution for SAP error message WB064 - Selection of materials not limited ?

  The SAP error message WB064 ("Selection of materials not limited") typically occurs in the context of inventory management or material requirements planning (MRP) when the system is unable to limit the selection of materials based on the criteria specified in the transaction or report you are running. This can happen in various scenarios, such as when generating reports, running MRP, or executing inventory-related transactions.
  Cause:
  
  
  Missing Selection Criteria: The selection criteria you provided may not be specific enough to limit the materials being processed. For example, if you are running a report without specifying a plant, material type, or other relevant parameters, the system may attempt to process all materials.
  
  
  Data Issues: There may be issues with the data in the system, such as missing or incorrect material master records, which can lead to the inability to limit the selection.
  
  
  Configuration Settings: The configuration settings in the system may not be set up to allow for proper filtering of materials based on the criteria you are using.
  
  
  User Authorizations: Sometimes, user authorizations may restrict access to certain materials, leading to unexpected behavior in selection.
  
  
  Solution:
  
  
  Review Selection Criteria: Ensure that you have specified adequate selection criteria in your transaction or report. This may include specifying a plant, material type, or other relevant filters to narrow down the selection.

  User Authorizations: Check your user authorizations to ensure that you have the necessary permissions to access the materials you are trying to select.
