• What is the cause and solution for SAP error message CAWUSL203 - You are not allowed to enter '*' for a field name ?

  The SAP error message CAWUSL203, which states "You are not allowed to enter '' for a field name," typically occurs when a user attempts to use an asterisk () as a wildcard character in a field name where it is not permitted. This can happen in various contexts within SAP, such as when defining selection criteria, filters, or in certain configuration settings.
  Cause:
  
  Invalid Input: The asterisk (*) is often used as a wildcard in many systems, but in this case, SAP does not allow it in specific fields where a precise value is expected.
  Field Restrictions: Certain fields in SAP have restrictions on the characters that can be entered, and the asterisk is not allowed in these cases.
  
  Solution:
  
  Remove the Asterisk: The immediate solution is to remove the asterisk (*) from the field name or input. Instead of using a wildcard, enter a specific value that meets the criteria you are trying to filter or search for.
  Check Documentation: Review the relevant SAP documentation or help files for the specific transaction or module you are working with to understand the valid input formats for the fields.
  Use Alternative Wildcards: If you need to perform a search or filter operation, consider using other valid wildcards or search techniques that are supported by SAP, such as using the question mark (?) for single character wildcards, if applicable.
