• What is the cause and solution for SAP error message OM521 - More than 1 entry as default entry selected for transaction &1 ?

  The SAP error message OM521 indicates that there is more than one default entry selected for a specific transaction, which is causing a conflict. This typically occurs in the context of configuration settings where the system expects a single default entry but finds multiple entries that meet the criteria.
  Cause:
  
  Multiple Default Settings: The most common cause of this error is that multiple entries have been marked as default for the same transaction or configuration setting in the system.
  Configuration Issues: This can happen if the configuration settings in the relevant module (like Material Management, Sales and Distribution, etc.) have not been set up correctly.
  Data Inconsistency: There may be inconsistencies in the master data or configuration data that lead to multiple defaults being defined.
  
  Solution:
  
  
  Check Configuration Settings:
  
  Navigate to the relevant configuration area in SAP (e.g., SPRO) and check the settings for the transaction indicated in the error message.
  Ensure that only one entry is marked as the default for the specific transaction.
  
  
  
  Review Master Data:
  
  Check the master data related to the transaction. For example, if the error is related to a material, check the material master records to ensure that only one default entry exists.
  
  
  
  Adjust Default Entries:
  
  If you find multiple entries marked as default, you will need to adjust the settings to ensure that only one entry is designated as the default. This may involve changing the settings in the configuration or updating the master data.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for the specific module you are working with to understand how default entries are defined and managed.
  
  
  
  Testing:
  
  After making changes, test the transaction again to ensure that the error has been resolved.
  
  
  
  Related Information:
  
  Transaction Codes: Depending on the module, you may need to use specific transaction codes to access configuration settings (e.g., SPRO for configuration, MM01 for material master).
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  User Roles and Authorizations: Ensure that you have the necessary authorizations to make changes to configuration settings or master data.
  
  If the issue persists after following these steps, it may be beneficial to consult with an SAP Basis or functional consultant who can provide deeper insights into the specific configuration and data setup in your SAP environment.
