ATP result as non-integer quantity

Question

I have a order which i created in UOM CAR.
1CAR = 150 PCE in my case
The ATP happens based on the Basic UOM which is there in Material master.
First UOM in order is converted to basic UOM. In this case 1 CAR = 150 PCE
Then ATP will be carried out.
After ATP  100PCE were available. So 0.66 CAR was confirmed in schedule line
But this is wrong and it should be in integer value only.
Is there a way i can make that happen. Some setting which i can do to avoid this.

There is no standard setting to change this behaviour. The system will always exexute ATP in base unit of measure. In your example, if you want the 0.66 to be rounded, you eed to use a user exiot. An extract from the note explains how to do this:
If you nevertheless want to use a rounding function for the confirmed
quantities, the EXIT_SAPLATPC_002 function module is provided as a user exit for
changing the result of the ATP check. In this case, the T006-ANDEC and
T006-DECAN fields must be analyzed depending on the unit of measure used. The
T_MDVEX-MNG02 quantity can then be adjusted accordingly.
So you need to discuss this further with your ABAPers.
