• What is the cause and solution for SAP error message M8112 - Only one supplier posting possible for net posting ?

  The SAP error message M8112 "Only one supplier posting possible for net posting" typically occurs in the context of inventory management and accounting when you are trying to post a goods movement or a financial transaction that involves multiple suppliers in a way that is not allowed by the system's configuration.
  Cause:
  This error usually arises due to the following reasons:
  
  
  Net Posting Configuration: The system is configured to allow only one supplier for net postings. This means that when you are trying to post a transaction that involves multiple suppliers, the system restricts this action to maintain the integrity of financial postings.
  
  
  Document Type Settings: The document type used for the transaction may be set up to only allow single supplier postings.
  
  
  Transaction Type: Certain transaction types in SAP may inherently restrict the ability to post multiple suppliers.
  
  
  Master Data Issues: There may be issues with the vendor master data or the way the suppliers are linked to the materials or transactions.
  
  
  Solution:
  To resolve the M8112 error, you can consider the following steps:
  
  
  Review the Transaction: Check the transaction you are trying to post. Ensure that it only involves one supplier. If multiple suppliers are involved, you may need to split the transaction into separate postings.
  
  
  Check Document Type Configuration: Review the configuration of the document type you are using for the transaction. You may need to adjust the settings to allow for multiple suppliers if that is appropriate for your business process.
  
  
  Consult with SAP Configuration Team: If you are unsure about the configuration settings, consult with your SAP configuration team or a functional consultant who can provide insights into the settings related to net postings and supplier handling.
  
  
  Vendor Master Data: Ensure that the vendor master data is correctly set up and that there are no inconsistencies that could be causing the issue.
