  Cause:

  Configuration Issues: If you are working with custom programs or configurations, the issue may arise from how parameters are defined in those contexts.
  
  Solution:
  
  Check Parameter Name: Review the parameter name you are using and ensure it starts with a letter. For example, instead of using 1Parameter, use Parameter1.
  Modify Code/Configuration: If you are working in ABAP or a configuration setting, modify the parameter name to comply with SAP's naming conventions.
  Testing: After making the necessary changes, test the transaction or program again to ensure that the error is resolved.
