How To Fix M3419 - Serial numbers can be managed only if base unit of measure is discrete

M3419 - Overview

• Message type: E = Error

• Message class: M3 - Material Master

• Message number: 419

• Message text: Serial numbers can be managed only if base unit of measure is discrete

What causes this issue?

You wanted to specify a serial number profile. However, this requires
the base unit of measure to be discrete (such as <LS>piece</> or
<LS>pallet</>). The unit of measure you have entered is not discrete
because it can be converted into other units of measure of the same
<DS:GLOS.3526C2A3AFAB52B9E10000009B38F974>dimension</> (for example,
kilograms to grams in the case of the dimension <LS>weight</>).

System Response

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

How to fix this error?

Enter a base unit of measure that is discrete, that is, dimensionless.

• What is the cause and solution for SAP error message M3419 - Serial numbers can be managed only if base unit of measure is discrete ?

  The SAP error message M3419 indicates that serial numbers can only be managed if the base unit of measure (UoM) for the material is set to a discrete unit. This error typically arises when you attempt to manage serial numbers for a material that is not defined with a discrete UoM.
  
  Cause:
  
  Base Unit of Measure: The material in question is defined with a base unit of measure that is not discrete (e.g., kilograms, liters, etc.). Serial numbers are typically used for items that are counted individually, such as machines, tools, or electronic devices.
  Material Master Configuration: The material master record may not be configured correctly to support serial number management.
  
  
  Solution:
  To resolve this error, you need to ensure that the material is set up with a discrete base unit of measure. Here are the steps to do this:
  
  
  Check Material Master:
  
  Go to the Material Master (Transaction Code: MM02).
  Enter the material number and select the
