• What is the cause and solution for SAP error message WY113 - Supplier & is one-time supplier: account group cannot be changed ?

  SAP Error Message:
  
  WY113: Supplier & is one-time supplier: account group cannot be changed
  
  Cause:
  This error occurs when you try to change the account group of a vendor master record that is flagged as a one-time supplier (one-time vendor). In SAP, one-time vendors are special vendor master records created for occasional or one-time transactions. The system restricts changing the account group for these vendors because the account group defines the structure and control of the vendor master data, and changing it could lead to inconsistencies or data integrity issues.
  
  Explanation:
  
  One-time supplier/vendor: A vendor master record created with the "one-time vendor" flag (usually account group like LIFNR with a specific one-time vendor account group).
  Account group: Defines the number range and field selection for vendor master data.
  When a vendor is marked as a one-time vendor, the system locks the account group to prevent changes.
  Attempting to change the account group for such a vendor triggers the WY113 error.
  
  
  Solution:
  
  Do not change the account group of a one-time vendor. Instead:
  
  If you need a vendor with a different account group, create a new vendor master record with the desired account group.
  If the vendor should no longer be a one-time vendor, you may need to create a new vendor master record with the correct account group and transfer any open transactions or data accordingly.
  
  
  If you mistakenly created a vendor as a one-time vendor and want to convert it, SAP does not provide a standard way to change the account group for existing vendor master records. You must create a new vendor master record.
  Review your business process to ensure that one-time vendors are only used for truly one-time transactions.
  
  
  Additional Information:
  
  
  Transaction codes involved:  
  
  XK02 (Change Vendor)  
  FK02 (Change Vendor - Accounting)  
  MK02 (Change Vendor - Purchasing)
  
  
  
  SAP Notes:
  
  There might be SAP Notes related to vendor master data and account group changes, but the fundamental restriction remains.
  
  
  Best practice:
  
  Use one-time vendors only for occasional transactions and avoid changing their account group. For regular vendors, use appropriate account groups from the start.
  
  
  
  If you need to handle a scenario where a vendor's account group must be changed, consider the following approach:
  
  Create a new vendor master record with the correct account group.
  Transfer open purchase orders, invoices, or other documents to the new vendor.
  Block or mark the old vendor as inactive.
  
  
  Summary:
  
  The error WY113 occurs because SAP does not allow changing the account group of a one-time vendor. The solution is to create a new vendor master record with the desired account group instead of trying to change the existing one-time vendor's account group.
