How To Fix W_011 - Material grp differs frm component material &1 and BOM header material &2

SAP Error Message - Details

• Message type: E = Error

• Message class: W_ - Upload CRM -> R3 BOMs / Structured Materials

• Message number: 011

• Message text: Material grp differs frm component material &1 and BOM header material &2

What causes this issue?

The header material &V1& is a prepack material. The component material
&V2& belongs to a different group than the BOM header material. In
Retail however, the material group of the BOM header for prepack
materials must agree with the material group of the components.

System Response

Processing cannot be carried out.

How to fix this error?

Ensure during the product upload, that the materials in OLTP are
created with the correct material group.

• What is the cause and solution for SAP error message W_011 - Material grp differs frm component material &1 and BOM header material &2 ?

  Certainly! Here's a detailed explanation of the SAP error message:
  
  SAP Error Message:
  W_011 Material grp differs frm component material &1 and BOM header material &2
  
  Meaning / Cause:
  This warning message occurs during the creation or processing of a Bill of Materials (BOM) when the material group of a component material (&1) differs from the material group of the BOM header material (&2).
  
  Material Group is a classification key used to group materials with similar characteristics.
  The system checks consistency between the BOM header material and its components.
  If the material group of a component does not match the material group of the BOM header, this warning is triggered.
  
  This is typically a consistency check to ensure BOM components belong to the same or compatible material groups as the BOM header.
  
  When does it occur?
  
  During BOM creation or change (transaction codes like CS01, CS02).
  During BOM explosion or usage.
  When components are assigned to a BOM header with a different material group.
  
  
  Impact:
  
  This is a warning message (W), not an error, so it does not stop the process.
  However, it indicates a potential inconsistency that might affect reporting, costing, or material planning.
  It helps maintain data integrity and consistency in material master and BOM data.
  
  
  Solution / How to resolve:
  
  
  Check Material Groups:
  
  Verify the material group of the BOM header material (transaction MM03).
  Verify the material group of the component material(s).
  
  
  
  Align Material Groups:
  
  If appropriate, change the material group of the component material(s) to match the BOM header material.
  Or, if the component material group is correct, consider changing the BOM header material group.
  
  
  
  Review BOM Structure:
  
  Confirm that the component is correctly assigned to this BOM.
  If the component belongs to a different material group for a valid reason, you may ignore the warning or document the exception.
  
  
  
  Customizing:
  
  If this warning is not relevant for your business process, you can adjust the message control in transaction OMSG to downgrade or suppress the warning.
  However, this is not generally recommended without proper analysis.
