• What is the cause and solution for SAP error message KT305 - Deletion not possible (transaction data). ?

  The SAP error message KT305 "Deletion not possible (transaction data)" typically occurs when you attempt to delete a cost center, internal order, or other master data that has associated transaction data. This means that there are existing postings or transactions linked to the object you are trying to delete, which prevents the deletion process.
  Cause:
  
  Existing Transactions: The primary reason for this error is that there are financial transactions or postings associated with the cost center or internal order you are trying to delete.
