How To Fix M3580 - Check the conversion factor for the base unit of the planning material

SAP Error Message - Details

• Message type: E = Error

• Message class: M3 - Material Master

• Message number: 580

• Message text: Check the conversion factor for the base unit of the planning material

What causes this issue?

If you do not specify a conversion factor for calculating quantities of
the material as quantities of the planning material, the system
proposes a conversion factor. This factor is determined as follows:
The system checks the alternative units of measure that are maintained
for the planning material. If an alternative unit is the same as the
base unit of the current material, the conversion factor is proposed
immediately. Otherwise, the system continues with point 2.
The system attempts to find a conversion factor using the standard
units of measure table. If is finds one, it proposes this value.
Otherwise, it continues with point 3.
The system proposes "1" as the conversion factor.
If you enter a conversion factor, the system asks you to check it. When
you enter a planning material the system cannot display its base unit
of measure until you select Enter.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
