  The SAP error message:
  WS_TOOL877 Function &1: &2 parameter &3 type has changed
  typically occurs during the import or transport of function modules or function groups when the parameter type of a function module has been changed in the source system compared to the target system.
  
  Explanation / Cause
  
  
  
  Cause:
  The error indicates that the type of a parameter in a function module has been changed in the source system after the function module was originally created or last transported to the target system. When you try to import or activate the function module in the target system, SAP detects that the parameter type differs from what is currently defined there.
  
  
  This can happen if:

  The function module was modified in the source system but the changes are inconsistent or incompatible with the target
