• What is the cause and solution for SAP error message WB2_ASGT157 - TC &1: Supplying plant cannot be changed. Items have pred or succ. ?

  The SAP error message WB2_ASGT157 indicates that there is an issue with changing the supplying plant for a particular item in a transaction. The message specifically states that the supplying plant cannot be changed because there are items that have predecessor (pred) or successor (succ) relationships.
  Cause:
  This error typically occurs in scenarios where:
  
  Predecessor/Successor Relationships: The item you are trying to change has dependencies on other items. For example, if you have a production order or a bill of materials (BOM) where certain components are linked to a main item, changing the supplying plant for that item can disrupt the established relationships.
  Data Integrity: SAP enforces data integrity rules to ensure that changes do not lead to inconsistencies in the system. Changing the supplying plant could lead to issues with inventory management, production planning, or order processing.
  
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Check Dependencies: Review the item in question to identify any predecessor or successor relationships. You can do this by checking the production order, BOM, or any related documents that might indicate dependencies.
  
  
  Remove Dependencies: If possible, remove or adjust the predecessor/successor relationships before attempting to change the supplying plant. This may involve:
  
  Deleting or modifying production orders.
  Adjusting BOMs or routing information.
  
  
  
  Consult Documentation: Refer to SAP documentation or your organization's internal guidelines for handling such changes. There may be specific procedures in place for managing plant changes.
  
  
  Use Alternative Methods: If changing the supplying plant is not feasible due to the dependencies, consider alternative methods such as:
  
  Creating a new item with the desired supplying plant.
  Transferring stock from the old plant to the new plant if applicable.
  
  
  
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting SAP Notes for any known issues or patches related to this error.
  
  
  Related Information:
  
  
  Transaction Codes: Familiarize yourself with relevant transaction codes that may help you analyze the situation, such as:

  SAP Notes: Check SAP Notes for any updates or specific fixes related to this error message. You can search for the error message number or related keywords in the SAP Support Portal.
