• What is the cause and solution for SAP error message CC827 - Special character '_' not allowed in parameter names ?

  The SAP error message CC827 indicates that a special character, specifically the underscore ('_'), is not allowed in parameter names within certain contexts in SAP. This error typically arises when you are trying to create or modify a parameter in a configuration or programming environment, such as ABAP or within certain transaction codes.
  Cause:
  The primary cause of this error is the use of the underscore character in the naming of parameters. SAP has specific naming conventions and restrictions for parameters, and the underscore is not permitted in certain contexts. This can happen in various scenarios, such as:
  
  When defining parameters in function modules, classes, or methods.
  When configuring certain settings in transaction codes that require parameter names.
  
  Solution:
  To resolve the CC827 error, you should:
  
  
  Rename the Parameter: Change the name of the parameter to remove the underscore. Use alternative naming conventions, such as camelCase or PascalCase, or simply concatenate words without special characters. For example, instead of my_parameter, you could use myParameter or myParameterName.
  
  
  Check Naming Conventions: Review the SAP documentation or guidelines for naming conventions in the specific context you are working in. Ensure that you are following the allowed naming patterns.
  
  
  Test Changes: After renaming the parameter, test the changes to ensure that the functionality remains intact and that the error no longer occurs.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for guidelines on naming conventions and restrictions for parameters in the specific module or programming language you are using.
  SAP Community: Engage with the SAP Community forums for additional insights and solutions from other users who may have encountered similar issues.
  Transaction Codes: If you are working within a specific transaction code, check if there are any known issues or updates related to parameter naming in that transaction.
  
  By following these steps, you should be able to resolve the CC827 error and successfully define your parameters without using the underscore character.
