• What is the cause and solution for SAP error message RFAC_QUICKFIX179 - Can't decide parameter type for &1, since it is defined with LIKE ?

  The SAP error message RFAC_QUICKFIX179 indicates that there is an issue with the parameter type definition in a program or function module. Specifically, the error arises when a parameter is defined using the LIKE keyword, but the system is unable to determine the exact data type for that parameter.
  
  Cause:
  
  LIKE Keyword Usage: The LIKE keyword is used to define a variable based on the data type of another field. If the reference field is not clearly defined or if it is ambiguous, the system cannot resolve the type for the parameter.
  Missing or Incorrect Data Element: The data element or field that is being referenced may not exist, or it may not have a clear definition in the data dictionary.
  Dynamic Typing Issues: If the program is trying to dynamically determine the type of a parameter at runtime, and it relies on a LIKE definition that is not resolvable, this error can occur.
