• What is the cause and solution for SAP error message T0937 - Posting key & allows no posting to customers ?

  The SAP error message T0937, which states "Posting key & allows no posting to customers," typically occurs when you attempt to post a transaction using a posting key that is not configured to allow postings to customer accounts. This can happen in various scenarios, such as during invoice postings, payment processing, or other financial transactions involving customer accounts.
  Cause:
  
  Incorrect Posting Key: The posting key you are using is not set up to allow postings to customer accounts. Each posting key in SAP is configured with specific rules regarding which account types it can post to (e.g., customer, vendor, general ledger).
  Configuration Issues: The configuration settings for the posting keys in the Financial Accounting (FI) module may not be set up correctly.
  Transaction Type: The type of transaction you are trying to perform may not be compatible with the selected posting key.
  
  Solution:
  
  
  Check Posting Key Configuration:
  
  Go to the transaction code OB41 (or navigate through the menu: SPRO > Financial Accounting > General Ledger > Document > Document Entry > Define Posting Keys).
  Look for the posting key you are using and check its configuration. Ensure that it is allowed to post to customer accounts.
  
  
  
  Use the Correct Posting Key:
  
  If the posting key you are using is not meant for customer postings, switch to a different posting key that is configured for customer accounts. Common posting keys for customer transactions include 01 (Debit) and 11 (Credit).
  
  
  
  Review Transaction Type:
  
  Ensure that the transaction type you are trying to execute is appropriate for the posting key you are using. For example, if you are trying to post a customer invoice, ensure you are using the correct transaction type that corresponds with the posting key.
  
  
  
  Consult with SAP Support or Configuration Team:
  
  If you are unsure about the configuration or need to make changes, consult with your SAP support team or the configuration team responsible for the FI module.
  
  
  
  Related Information:
  
  Posting Keys: Posting keys are two-digit numbers that determine the type of transaction being posted (debit or credit) and the account types that can be affected.
  Customer Accounts: In SAP, customer accounts are part of the Accounts Receivable module, and specific posting keys are designated for transactions involving these accounts.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as FB01 (Post Document), F-28 (Post Incoming Payments), and others that may be relevant to your posting activities.
  
  By following these steps, you should be able to resolve the T0937 error and successfully post your transactions.
