When using Procurement Category instead of Items or Products, the default value in 'Units' field on Purchase Order Line details is blank. If a user does not select a Unit from the drop down and instead leaves the value blank, then enters a decimal quantity in the 'Quantity ordered' field, the system will round the value to whole units.

For example, the quantity 4.75 is entered - system will override the value entered with 5. If we make 'Units' a required value and move the field to the left so a user cannot skip over the 'Units' field by default, the issue is mitigated but this requires either customization or forcing form changes and publishing to the user groups which over-writes their default form in PO Lines.

If the system updated value for the whole unit is not corrected, the PO Line quantity can be incorrect and result in order errors and invoice matching errors.
