• What is the cause and solution for SAP error message T0935 - Posting key & not defined for debit postings ?

  The SAP error message T0935, which states "Posting key & not defined for debit postings," typically occurs when you attempt to post a transaction using a posting key that is not configured to allow debit postings in the system. Posting keys in SAP are used to define the type of transaction being posted (e.g., debit or credit) and the account types that can be posted to.
  Cause:
  
  Incorrect Posting Key: The posting key you are using is not set up to allow debit postings. Each posting key has specific configurations that determine whether it can be used for debit or credit transactions.
  Configuration Issues: The posting key may not be properly defined in the system configuration, or it may have been modified incorrectly.
  Account Type Restrictions: The account type associated with the posting key may not allow debit postings.
  
  Solution:
  
  
  Check Posting Key Configuration:
  
  Go to the SAP transaction code OB14 (Define Posting Keys).
  Look for the posting key that is causing the error. Check its configuration to see if it is set up for debit postings.
  Ensure that the "Debit" option is selected for the posting key in question.
  
  
  
  Use the Correct Posting Key:
  
  If the posting key is not meant for debit postings, use a different posting key that is configured for debit transactions. Common debit posting keys include 40 (for general ledger accounts) and 50 (for customer accounts).
  
  
  
  Consult with SAP Administrator:
  
  If you do not have access to change the configuration, consult with your SAP administrator or the finance team to ensure that the posting keys are set up correctly according to your organization's requirements.
  
  
  
  Review Account Types:
  
  Ensure that the account type you are trying to post to is compatible with the posting key being used. For example, if you are trying to post to a vendor account, ensure that the posting key allows for that type of account.
  
  
  
  Related Information:
  
  Posting Keys: Posting keys are defined in the Financial Accounting (FI) module and are crucial for determining how transactions are recorded in the general ledger.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FB01 (Post Document), FB50 (G/L Account Document), and OB14 (Define Posting Keys) for troubleshooting.
  SAP Documentation: Refer to SAP Help documentation for detailed information on posting keys and their configurations.
  
  By following these steps, you should be able to resolve the T0935 error and successfully post your transactions.
