when using syncsort utility, there are some limitations:

• DFSORT (DATE3) format has no equivalent on syncsort.
• DFSORT statements (outrec, inrec) are not fully supported in the following situations:
  • If a key or a filed definition of an outrec field cut a field constant type, an error shows up (MT_ERROR in SYSIN translation) and :#PHX in ksh.
  • If a key or a field definition of an outrec field is not included in the inrec, an error shows up.
  • Cases with SUM are not handled.
