• What is the cause and solution for SAP error message SALV_BS_MSG302 - Placeholders are not allowed in value range limits ?

  The SAP error message SALV_BS_MSG302 indicates that placeholders are not allowed in value range limits when using the ALV (ABAP List Viewer) functionality. This error typically arises when you are trying to set up a value range for a field in an ALV grid or list, and you have inadvertently included placeholders (like &, *, or other wildcard characters) in the value range limits.
  Cause:
  
  Placeholders in Value Ranges: The error occurs when you attempt to define a value range for a field using placeholders or wildcards. For example, if you are trying to filter or set limits on a field and you use a placeholder like * or &, the ALV does not accept this format.
  Incorrect Data Type: The field you are trying to set limits on may not support the use of placeholders due to its data type or the way it is defined in the data dictionary.
  
  Solution:
  
  
  Remove Placeholders: Check the code where you are defining the value range limits and ensure that you are using actual values instead of placeholders. For example, instead of using * or &, specify concrete values that you want to filter on.
  Example:
  DATA: lt_range TYPE RANGE OF your_field_type.
  APPEND VALUE #( sign = 'I' option = 'EQ' low = 'ActualValue' ) TO lt_range.
  
  
  Use Valid Data Types: Ensure that the data type of the field you are working with is compatible with the value range you are trying to set. If the field is a character type, ensure you are using valid character strings.
  
  
  Check ALV Configuration: Review the configuration of your ALV grid or list to ensure that you are not inadvertently setting up filters or limits that include placeholders.
  
  
  Debugging: If you are unsure where the issue is occurring, you can use debugging tools in SAP to step through the code and identify where the value range is being set incorrectly.
