What is the consequence of defining different display decimals for QNTY and QTYINV?
Document 626475.1 has a good explanation what to do when changing the display decimals.
A yellow remark: "The recommendation is the display decimals value of data item QNTY should not be less than the display decimals value of class data item QTYINV and data items belonging to class data item QTYINV to avoid rounding."
But is it not the other way around? If I have parts defined in the Bill of Material (QNTY) with 5 decimals and the inventory (QTYINV) with 2 decimals, generating a work order for #100 will lead to rounding issues in my opinion. #100 x 0,12345 = 12,34500 -> 12,34 in the F3111
When the display decimals of QNTY (i.e. 2) is less than QTYINV (i.e. 3) you will never have a rounding issue, no matter what the work order quantity is. #1 x 0,12 -> 0,120 in the F3111.
