How To Fix CF087 - Unit of measure & not defined (check entry)

CF087 - Overview

• Message type: E = Error

• Message class: CF - PRT management messages

• Message number: 087

• Message text: Unit of measure & not defined (check entry)

What causes this issue?

You entered the unit of measure &V1&. The dimension of this unit of
measure corresponds neither to the dimension of the base unit of
measure &V2& nor to the dimension of the output unit of measure &V3& of
the production resource/tool material.

How to fix this error?

Enter a unit of measure whose dimension corresponds to the dimension of
the base unit of measure &V2& or with that of the output unit of
measure &V3& of the material PRT.
If you enter a dimensionless unit of measure, this must correspond to
the base unit of measure or the output unit of measure of the material
PRT. You should not enter another dimensionless unit of measure.

  Missing UoM in Customizing: The unit of measure might not be included in the relevant customizing settings for the specific application area.
  
  
  Solution:
  
  
  Check UoM Definition:
  
  Go to the transaction code CUNI (Unit of Measure Conversion) or OMN1 (Define Units of Measure) to
