SAP Business ByDesign

Reproducing the Issue

  1. Go to Products Portfolio workcenter
  2. Go to Products view
  3. Select Material PQR(PQR refers to the material id)
  4. View all
  5. In the General tab, under the Quantity Conversions
  6. You maintain the quantity as grams and in the corresponding quantity, you maintain - Kilograms
  7. The system displays an error message - 
    Cannot convert between UoM Gram and Kilogram; they are the same or of same type


Expected behavior.

The Quantity Conversions is when you can specify the equivalent measurement of one unit to another unit, for example, one pallet contains 15 boxes.

In this case, a gram is a measure of weight or mass equivalent to 1 1000 th of a kilogram. Hence there is no need to specify it under quantity conversions. Same for Meter and Kilometer, Liter and Milliliter, etc.


We suggest to maintain a different Unit of measure in the corresponding quantity and the error will not appear.
