• What is the cause and solution for SAP error message CNV_PE659 - MARC-MMSTA is active for at least one material/plant ?

  The SAP error message CNV_PE659 indicates that the table MARC (which contains plant data for materials) has the field MMSTA (Material Status) active for at least one material/plant combination. This typically occurs during data migration or conversion processes, particularly when using SAP's data migration tools.
  Cause:
  The error arises when the system detects that there are materials in the MARC table that have a material status that prevents certain operations. The material status can restrict activities such as procurement, sales, or inventory management for the affected materials. This is often a result of:
  
  Material Status Settings: The material status (MMSTA) is set to a value that restricts the material's use in certain processes.
  Data Migration Issues: During data migration, the system checks for active material statuses that may conflict with the migration process.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Affected Materials:
  
  Use transaction codes like SE16N or SE11 to view the MARC table and identify which materials have an active MMSTA.
  You can run a query to filter materials based on the MMSTA field.
  
  
  
  Review Material Status:
  
  Check the material status settings for the identified materials. You can do this using transaction MM03 (Display Material) and navigating to the "Plant Data" view.
  Determine if the material status is appropriate for your business processes.
  
  
  
  Change Material Status:
  
  If the material status is not needed, you can change it using transaction MM02 (Change Material) to set the MMSTA to a status that allows the desired operations.
  Ensure that the new status aligns with your business requirements.
  
  
  
  Data Migration Adjustments:
  
  If you are in the process of data migration, ensure that the migration tool is configured to handle materials with specific statuses appropriately.
  You may need to exclude certain materials from the migration if they are not relevant.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the CNV_PE659 error for any specific guidance or updates.
