SAP Error Message - Details

• Message type: E = Error

• Message class: MU - Maintenance of structured materials

• Message number: 129

• Message text: Procurement material &1 could not be created. Please check the UoM data.

What causes this issue?

You want to create or change procurement material &V1& used in the
context of logistical materials.
The use of logistical materials has been enabled in Customizing by
specifying the base unit of measure to be used for the creation of
procurement materials. However, the unit of measure data for material
&V1& does not match the unit of measure specified in Customizing.

System Response

To keep the material data consistent, the system prevents you from
saving this material.

How to fix this error?

Please check the base unit of measure that is specified for the creation
of procurement materials in the Customizing activity
<DS:SIMG.LOGISTICAL_PRODUCTS>Define Handling of Logistical Products</>.
If the base unit of measure to be used should be the same as the sales
material (TWPA-PROCMT_PROD_BASE_UOM = 1), then the base unit of measure
of procurement material &V1& must have the same value as the base unit
of measure of sales material &V2&.
If the base unit of measure to be used should be the same as the
procurement material (TWPA-PROCMT_PROD_BASE_UOM = 2), then the base unit
of measure of procurement material &V1& must have the same value as the
issue unit of measure of procurement material &V1&.
If you want to distribute data using ALE, in the source system and the
target system, make sure that the same setting is made in the
Customizing activity <LS>Define Handling of Logistical Products</>.
