As the description says, the meaning of that field is to set the internal length of the field in Bytes. During my whole career as ABAP Developer, I had never filled that field manually. Usually you’ll not bother yourself about it. But if you do, then take into consideration following information:

  • Length is in Bytes, so remember that it doesn’t mean, that one character takes one Byte
  • In display mode, you’ll not notice probably any change
  • When you’ll setup this incorrectly, you may have problems when you allow grid to be editable, for example:
    When I’ve set the INTLEN to ‘2’ for column FLTIME, then although I’ve entered the value of ‘12’ into the column, system didn’t allowed me to save it.
