• What is the cause and solution for SAP error message /PM0/ABU_MESSAGES043 - Only a default value for &1 &2 is allowed ?

  The SAP error message /PM0/ABU_MESSAGES043: Only a default value for &1 &2 is allowed typically occurs in the context of SAP Plant Maintenance (PM) or related modules when there is an issue with the configuration of default values for certain fields in a transaction or a program.
  Cause:
  This error message usually indicates that the system is expecting a default value for a specific field (represented by &1 and &2 in the message) but has encountered a situation where multiple values or an invalid value is being provided instead. This can happen due to:
  
  Configuration Issues: The default values for certain fields may not be properly configured in the system.
  Data Entry Errors: Users may be entering values that are not allowed or expected in the context of the transaction.
  Custom Code: If there are custom enhancements or modifications in the system, they might be causing conflicts with the expected behavior of standard transactions.
  Missing Authorizations: Sometimes, the user may not have the necessary authorizations to access or modify certain fields, leading to this error.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Configuration:
  
  Review the configuration settings for the relevant module (e.g., PM) to ensure that default values are correctly set up for the fields in question.
  Use transaction codes like SPRO to access the configuration settings and verify the default values.
  
  
  
  Data Entry Validation:
  
  Ensure that users are entering valid data in the fields. Provide training or guidelines on what values are acceptable.
  If applicable, check for any validation rules that might be causing the issue.
  
  
  
  Review Custom Code:
  
  If there are any custom enhancements or modifications, review the code to ensure it is not interfering with the standard behavior of the transaction.
  Consult with your ABAP developers if necessary.
  
  
  
  Check Authorizations:
  
  Verify that the user has the necessary authorizations to access and modify the fields in question. Use transaction SU53 to check for authorization issues after the error occurs.
