How To Fix MU135 - Base UoM &1 does not match BOM data for sales material &2.

MU135 - Overview

• Message type: E = Error

• Message class: MU - Maintenance of structured materials

• Message number: 135

• Message text: Base UoM &1 does not match BOM data for sales material &2.

What causes this issue?

You want to create procurement material &V3& based on sales material
&V2& to be used in the context of logistical materials.
A bill of material (BOM) for sales material &V2& contains empties. The
selected base unit of measure (UoM) &V1& for procurement material &V3&
does not match the existing BOM data for sales material &V2& for one of
the following reasons:
At least one relevant BOM exists for sales material &V2& where the
number of BOM components does not match the number of BOM components for
the selected base UoM &V1&.
At least one BOM exist for sales material &V2& that contains BOM
components that differ to the components in the BOM for the selected
base UoM &V1&.

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 base UoM to create the procurement
material. Make sure that the BOM data in the resulting procurement
material is identical to the data in the BOMs for the base UoM, the
issue unit<(>,<)> and the order unit.
If this is not possible, choose another sales material to create the
procurement material.

• What is the cause and solution for SAP error message MU135 - Base UoM &1 does not match BOM data for sales material &2. ?

  The SAP error message MU135 indicates that there is a mismatch between the base unit of measure (UoM) defined for a material and the unit of measure specified in the Bill of Materials (BOM) for that material. This error typically occurs when you are trying to perform operations such as creating a sales order, production order, or any other transaction that involves the material in question.
  
  Cause:
  
  Mismatch in UoM: The base unit of measure for the sales material does not match the unit of measure defined in the BOM. For example, if the base UoM for a material is set to "EA" (each) but the BOM specifies "KG" (kilograms), this will trigger the error.
  Incorrect BOM Configuration: The BOM may have been created or modified incorrectly, leading to discrepancies in the units of measure.
  Material Master Data Issues: The material master data may not be correctly maintained, leading to inconsistencies between the BOM
