Smart SAP Assistant

• What is the cause and solution for SAP error message WB2_ASGT153 - TC &1, item &2: Supplier cannot be changed. Item has pred or succ. ?

  The SAP error message WB2_ASGT153 indicates that you are trying to change the supplier for a specific item in a purchasing document (like a purchase order or a contract), but the system is preventing this change because the item has predecessor or successor relationships defined. This typically occurs in the context of procurement processes where items are linked to one another, and changing the supplier for one item could disrupt these relationships.
  Cause:
  
  Predecessor or Successor Relationships: The item you are trying to modify has been linked to other items in a way that changing the supplier would affect the integrity of these relationships. For example, if item A is a predecessor to item B, changing the supplier for item A could impact item B.
  Document Status: The document may be in a status that does not allow changes to suppliers, such as being partially processed or already confirmed.
  Configuration Settings: There may be specific configuration settings in your SAP system that enforce strict rules regarding supplier changes for items with dependencies.
  
  Solution:
  
  Review Relationships: Check the predecessor and successor relationships for the item in question. You may need to adjust these relationships before changing the supplier.
  Change Document Status: Ensure that the document is in a status that allows for changes. If it is locked or in a completed state, you may need to revert it to a status that allows modifications.
  Consult with Stakeholders: If the item is part of a larger procurement process, consult with relevant stakeholders (e.g., procurement team, project managers) to understand the implications of changing the supplier.
  Use Alternative Methods: If changing the supplier is not feasible, consider creating a new item with the desired supplier and removing the old item from the document if appropriate.
  SAP Notes and Documentation: Check SAP Notes or documentation for any specific guidance related to this error message. There may be updates or patches that address this issue.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as ME22N (Change Purchase Order) or ME31K (Create Contract) to navigate the purchasing documents.
  SAP Help Portal: Utilize the SAP Help Portal for detailed documentation on managing purchasing documents and understanding item relationships.
  User Roles and Permissions: Ensure that you have the necessary permissions to make changes to suppliers in the purchasing documents.
  
  If the issue persists after trying the above solutions, it may be beneficial to reach out to your SAP support team or consult with an SAP expert for further assistance.
