How To Fix MU134 - BOMs for order unit &1 and issue unit &2 must match for material &3.

MU134 - Overview

• Message type: E = Error

• Message class: MU - Maintenance of structured materials

• Message number: 134

• Message text: BOMs for order unit &1 and issue unit &2 must match for material &3.

What causes this issue?

You want to create procurement material &V4& based on sales material
&V3& to be used in the context of logistical materials.
A bill of material (BOM) for sales material &V3& contains empties. To
create a consistent procurement material, the BOM for issue unit &V1&
and order unit &V2& must be identical.
The BOMs for the order unit and the issue unit must have the same number
of BOM components and the BOM components must be the same in the BOM for
the order unit and the issue unit.

System Response

To avoid a data inconsistency in the material master and to ensure that
the procurement material can be correctly used in logistics processes,
the system stops processing and does not allow you to create the
material master data.

How to fix this error?

If possible<(>,<)> choose another issue unit or order unit to create
procurement material &V4&. Make sure that a BOM exists for the chosen
issue unit and that the BOMs for the issue unit and the order unit are
identical.
You can also try to adapt the BOMs for issue unit &V1& and order unit
&V2& so that these BOMs are identical.
If it is not possible to choose another unit of measure nor adapt the
BOMs<(>,<)> choose another material to create the procurement material.

• What is the cause and solution for SAP error message MU134 - BOMs for order unit &1 and issue unit &2 must match for material &3. ?

  The SAP error message MU134 indicates a mismatch between the order unit and the issue unit for a Bill of Materials (BOM) in the context of a specific material. This error typically arises when you are trying to create or process a production order, and the units of measure (UoM) for the BOM do not align with the units specified in the order.
  
  Cause:
  
  Unit of Measure Mismatch: The order unit (the unit in which the order is created) does not match the issue unit (the unit in which the components are issued) defined in the BOM for the specified material.
  BOM Configuration: The BOM may be configured incorrectly, or the material master data may not be set up properly.
  Material Master Settings: The material master may have different units of measure defined that do not correspond with the BOM settings.
  
  
  Solution:
  
  
  Check BOM Configuration:
  
  Go to the BOM transaction (CS01, CS02, or CS03) and verify the
