How To Fix MU070 - The material &1 is already a component of a structured material

MU070 - Overview

• Message type: E = Error

• Message class: MU - Maintenance of structured materials

• Message number: 070

• Message text: The material &1 is already a component of a structured material

What causes this issue?

It is not possible to assign an empties bill of material (empties BOM)
to the material &V1& because this material is already a component for a
set, display, or prepack (known collectively as
<DS:GLOS.3526BBD7AFAB52B9E10000009B38F974>structured materials</>).

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?

Create a new <DS:GLOS.352A7ADBD3895CD5E10000009B38F974>full product</>
and assign the required empties BOM to it.
If the material &V1& has been assigned to a structured material by
mistake, you can remove it from the structured material concerned if
the structured material is not yet used logistically. You can then
create the empties BOM.

Procedure for System Administrators

The assignment of empties BOMs to the components of a structured
material would result in multilevel BOMs which are not presently
supported in SAP Retail.

• What is the cause and solution for SAP error message MU070 - The material &1 is already a component of a structured material ?

  The SAP error message MU070 indicates that the material you are trying to use is already part of a structured material (such as a bill of materials or a configurable material). This typically occurs when you attempt to add a material that is already included in another structured material as a component.
  
  Cause:
  
  Material Already in Use: The material you are trying to add is already defined as a component in another structured material (e.g., a Bill of Materials (BOM)).
  
  Configuration Issues: There may be configuration settings that prevent the addition of materials that are already part of another structure.
  Data Integrity: SAP enforces data integrity rules to prevent duplication and conflicts in material usage.
  
  
  Solution:
  
  Check Existing Structures: Review the existing structured materials (BOMs or configurable materials) to see where the material is already being used. You can do this by using transaction codes like CS03 (Display BOM) or CS12 (BOM Level Display).
