As of Release 3.0, you have the option of entering your own conditions for individual order units. During the source determination process, the system will then offer you the order units for which prices have been maintained.
If none of the conditions that are dependent on the order unit are
maintained, you can order in the order units that are maintained in the
purchasing info record or in the material master record.
If, for example, prices have been entered for the order units "crate" and
"pallet" in an info record, you can only order from the vendor in these order
units, not in the unit "piece".
You determine whether you are going to work with conditions per order unit via the indicator "Variable order unit" in the general data of the purchasing info record.
