• What is the cause and solution for SAP error message O7091 - Define only one transaction as default for technical category &1 ?

  The SAP error message O7091, which states "Define only one transaction as default for technical category &1," typically occurs when there is a configuration issue in the SAP system related to the assignment of transactions to a technical category. This error indicates that multiple transactions have been defined as the default for a specific technical category, which is not allowed.
  Cause:
  The primary cause of this error is that in the configuration settings for the technical category (identified by &1), more than one transaction has been marked as the default transaction. SAP requires that only one transaction can be designated as the default for each technical category to avoid ambiguity in processing.

  To resolve this error, you need to review the configuration settings for the technical category in question and ensure that only one transaction is set as the default. Here are the steps to do this:
  
  
  Access the Configuration:

  Review Default Transactions:
  
  Look for the technical category identified by &1 in the error message.
  Check the list of transactions associated with this category and identify which ones are marked as default.
  
  
  
  Modify the Configuration:
  
  If you find multiple transactions marked as default, decide which one should remain as the default.
  Remove the default designation from the other transactions.
  
  
  
  Save Changes:
