• What is the cause and solution for SAP error message PIC01402 - Material &2 has no defined relationship to material &1 ?

  The SAP error message PIC01402 indicates that there is no defined relationship between two materials in the system. This typically occurs in the context of Product Lifecycle Management (PLM) or when working with material master data, particularly in scenarios involving bill of materials (BOM), material classification, or product structure.
  Cause:
  
  
  Missing Relationship Definition: The primary cause of this error is that the system does not have a defined relationship between the two materials specified in the error message. This could be due to:
  
  The relationship not being created in the system.
  The relationship being deleted or not maintained properly.
  Incorrect configuration or settings in the material master data.
  
  
  
  Data Inconsistency: There may be inconsistencies in the data, such as missing entries in the relevant tables that define relationships between materials.
  
  
  Incorrect Usage: The error may also arise if the user is trying to perform an operation that requires a relationship that has not been established.
  
  
  Solution:
  
  
  Define the Relationship:
  
  Go to the relevant transaction in SAP (e.g., CS01 for creating BOM, CS02 for changing BOM, or MM01 for material master) and ensure that the relationship between the two materials is defined.
  If you are working with BOMs, ensure that the components are correctly assigned to the parent material.
  
  
  
  Check Material Master Data:
  
  Verify the material master records for both materials involved. Ensure that they are correctly set up and that all necessary views are maintained.
  Use transaction MM03 to display the material master and check for any missing data.
  
  
  
  Use Transaction Codes:
  
  Use transaction codes like CS11 (Display BOM) or CS12 (BOM Comparison) to check if the BOMs are correctly defined and if the relationships exist.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to material relationships and BOMs to ensure that you are following the correct procedures.
  
  
  
  Check for Authorizations:
  
  Ensure that you have the necessary authorizations to create or modify relationships between materials.
  
  
  
  Contact SAP Support:
  
  If the issue persists after checking the above points, consider reaching out to SAP support for further assistance, especially if it seems to be a system-related issue.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MM01, MM02, MM03 (Material Master), CS01, CS02, CS03 (BOM), and CS11 (Display BOM).
  SAP Notes: Check for any SAP Notes related to this error message for potential patches or updates that may resolve the issue.
  User Manuals: Refer to user manuals or training materials specific to your organization’s SAP implementation for guidance on managing material relationships.
