As you can imagine, INTTYPE is just a presentation of DATATYPE in internal SAP format in most of cases. I wrote most of cases because it can also say if the field in internal table is a reference to other type, or for example a table.
Just like DATATYPE, you don’t need to fill this field manually, when you’ll leave it empty, ALV grid will automatically setup a proper type according to referenced internal table field. But if you’ll have unstoppable need of filling it, then the behaviour of the column will be exactly the same like you would use DATATYPE field, means JUST, OUTPUTLEN, INTTYPE, INTLEN and DD_OUTLEN fields will be also field and the difference on the screen will be not that huge.
