• What is the cause and solution for SAP error message UC794 - Purely numeric sender field names are not allowed ?

  The SAP error message UC794 indicates that there is an issue with the sender field names in your data transfer or configuration. Specifically, it states that purely numeric sender field names are not allowed. This typically occurs in scenarios involving data transfer, such as when using IDocs, BAPIs, or other data interfaces.
  Cause:
  The error arises when a field name in your data structure is purely numeric (e.g., "12345"). SAP requires that field names must start with a letter and can include letters, numbers, and underscores, but cannot be purely numeric. This restriction is in place to ensure that field names are valid identifiers in the SAP system.
  Solution:
  To resolve this error, you need to modify the sender field names to ensure they comply with SAP's naming conventions. Here are the steps you can take:
  
  
  Identify the Numeric Field Names: Review the data structure or mapping configuration that is causing the error. Look for any field names that are purely numeric.
  
  
  Rename the Fields: Change the purely numeric field names to valid names. For example, if you have a field named "12345", you could rename it to "Field_12345" or "NumField_12345".
  
  
  Update the Data Transfer Logic: If the field names are used in any data transfer logic (like mapping or transformation), ensure that you update those references to the new field names.
  
  
  Test the Changes: After making the changes, test the data transfer or process again to ensure that the error is resolved.
  
  
  Related Information:
  
  Field Naming Conventions: Familiarize yourself with SAP's field naming conventions to avoid similar issues in the future. Field names should start with a letter and can include letters, numbers, and underscores.
  Documentation: Check SAP documentation or help resources for more information on data transfer processes and naming conventions.
  Debugging: If you are unsure which field is causing the issue, you may need to debug the process or check logs to identify the problematic field.
  
  By following these steps, you should be able to resolve the UC794 error and ensure that your data transfer processes run smoothly.
