How To Fix M3028 - Alternative units of measure have been checked and corrected

SAP Error Message - Details

• Message type: E = Error

• Message class: M3 - Material Master

• Message number: 028

• Message text: Alternative units of measure have been checked and corrected

What causes this issue?

You have entered conversion factors for the alternative units of
measure. However, these conversion factors
either do not correspond to the values in the unit of measurement table
(example 1)
or are inconsistent (example 2)

System Response

The system has checked the values for consistency and, where necessary,
corrected them.
&EXAMPLE& 1
You choose G as the base unit and KG as the alternative unit.
According to the table, 1,000 g = 1 kg
You enter 900 g = 1 kg
The table specifies that 1,000 g = 1 kg. The system therefore
overwrites your entry 900 with 1,000.
&EXAMPLE& 2
You choose PC as the base unit, KG as the first alternative unit, and G
as the second alternative unit.
According to the table, 1 kg = 1,000 g
You enter 2 pc = 1 kg and 2 pc = 900 g
The table and the first entry specify that 2 pc = 1,000 g. The system
therefore overwrites the second entry of 900 with 1,000.
