What causes this issue?

When you enter a reservation without specifying a batch, you can enter
both in unit of issue and stockkeeping unit. You can therefore define a
conversion ratio, which is different from the one defined in the
material master, between unit of issue and stockkeeping unit for this
reservation.

System Response

You can only enter in unit of issue and stockkeeeping unit. From the
stockkeeping unit, quantities are calculated in the other alternative
units of measure. The system uses the conversion factors entered in the
material master to do this.
