• What is the cause and solution for SAP error message 56320 - Order/project/cost center (Combined entry is not allowed) ?

  The SAP error message 56320, which states "Order/project/cost center (Combined entry is not allowed)," typically occurs when there is an attempt to post a transaction that combines different types of cost objects in a way that is not permitted by the system configuration. This error is often encountered in the context of financial postings, such as when trying to allocate costs or expenses to multiple cost objects that are not compatible.
  Cause:
  
  
  Incompatible Cost Objects: The error arises when you try to post to a combination of cost objects (like orders, projects, and cost centers) that are not allowed to be combined in a single transaction. For example, you might be trying to post costs to both a cost center and an internal order in the same line item.
  
  
  Configuration Settings: The system configuration may restrict certain combinations of cost objects. This is often set up in the controlling (CO) module of SAP.
  
  
  Transaction Type Restrictions: Certain transaction types may have specific rules regarding which cost objects can be used together.
  
  
  Solution:
  
  
  Review the Posting: Check the transaction you are trying to post. Ensure that you are not mixing incompatible cost objects. For example, if you are posting to a cost center, do not include an internal order or project in the same line item.
  
  
  Separate Transactions: If you need to post to multiple cost objects, consider breaking the transaction into separate postings. For instance, post the costs to the cost center in one transaction and to the internal order in another.
  
  
  Check Configuration: If you believe the combination should be allowed, review the configuration settings in the controlling module. You may need to consult with your SAP CO consultant to adjust the settings if necessary.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on the allowed combinations of cost objects for the type of transaction you are processing.
  
  
  Error Message Analysis: Use transaction codes like SE91 to analyze the error message further and understand the specific conditions under which it is triggered.

  User Exits and BAdIs: If your organization has custom developments, check if there are any user exits or BAdIs that might be influencing the behavior of cost object postings.
  Training and Documentation: Ensure that users are trained on the proper procedures for posting transactions in SAP to avoid common pitfalls that lead to this error.
