  Error Message
  W8106: Constants cannot begin with '%' or '&'
  
  Cause
  This warning occurs when you define a constant in ABAP code that starts with the characters % or &. In ABAP, constants are not allowed to begin with these special characters because:
  
  % and & are reserved for system variables or special syntax elements.
  Using these characters at the start of a constant name or value can cause ambiguity or conflicts in the ABAP parser.
  
  For example, the following is not allowed:
  CONSTANTS c_example TYPE c VALUE '%test'.
  CONSTANTS c_example2 TYPE c VALUE '&test'.
  
  Solution
  
  
  Do not start constant values with % or &.
  Change the constant value so that it does not begin with these characters.
  
  
  If you need to use % or & as part of the constant value, place them after the first character, for example:
  
  
  CONSTANTS c_example TYPE c VALUE 'A%test'.
