• What is the cause and solution for SAP error message WB2B2158 - Supplier can be maintained for purchase side only. Shadow item &1|&2 ?

  The SAP error message WB2B2158 indicates that there is an issue with maintaining a supplier for a specific item in the system. The message states that the supplier can only be maintained for the purchase side, and it refers to a "shadow item." This typically occurs in scenarios involving materials that are set up for both sales and purchasing but have restrictions on how suppliers can be assigned.
  Cause:
  
  Shadow Item: The term "shadow item" refers to a material that exists in the system for both sales and purchasing but is not fully configured for both sides. This can happen if the item is primarily set up for sales and does not have the necessary purchasing data.
  Configuration Issues: The material may not be configured correctly in the material master, particularly in the purchasing view.
  Supplier Assignment: The supplier you are trying to assign may not be valid for the purchasing side of the material.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03) and check the purchasing view for the material in question.
  Ensure that the purchasing data is correctly maintained, including the supplier information.
  
  
  
  Maintain Supplier for Purchasing:
  
  If the material is intended to be purchased, ensure that the supplier is assigned in the purchasing view of the material master.
  If the supplier is not assigned, you can do this through transaction code MM02 (Change Material) and navigate to the purchasing view.
  
  
  
  Review Item Category:
  
  Check the item category of the material. Some item categories may restrict supplier assignments. Ensure that the item category allows for supplier maintenance.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team for specific configurations related to shadow items and supplier assignments.
  
  
  
  Check for Customizations:
