• What is the cause and solution for SAP error message WS_TOOL878 - Function &1: &2 parameter &3 type was removed ?

  The SAP error message:
  WS_TOOL878 Function &1: &2 parameter &3 type was removed
  Meaning / Cause
  This error occurs when a function module or method parameter's data type has been removed or is no longer available in the system. Specifically, the function module or method (&1 and &2) references a parameter (&3) whose data type has been deleted or is missing in the current system environment.
  This situation typically arises in scenarios such as:
  
  Transporting function modules or methods between systems where the data type does not exist in the target system.
  After deletion or modification of data dictionary objects (like data elements, structures, or table types) that are used as parameter types.
  During upgrade or patching activities where certain data types are deprecated or removed.
  When custom developments reference obsolete or deleted types.
  
  Where it occurs
  
  In Function Builder (SE37) or Class Builder (SE24) when activating or adjusting function modules or methods.
  During runtime when the system tries to call a function module or method with a missing parameter type.
  During import/transport of development objects.
  
  
  Solution / How to fix
  
  
  Check the missing data type:
  
  Identify the exact data type that was removed (parameter &3).
  Use transaction SE11 to check if the data type exists.
  If it was deleted unintentionally, restore it from a backup or transport.
  
  
  
  Adjust the function module or method:
  
  If the data type is obsolete and should not be restored, modify the function module or method to use an existing data type.
  Change the parameter type to a valid data type.
  Activate the function module or method again.
  
  
  
  Check transports:
  
  If the error appeared after a transport, verify that all dependent objects (data types, structures, table types) were included in the transport.
  Import missing objects or adjust the transport sequence.
  
  
  
  Check for system inconsistencies:
  
  Run consistency checks in SE37 or SE24.
  Use transaction SLIN or SCI to check for syntax or consistency errors.
