• What is the cause and solution for SAP error message KA306 - Only overhead types 1 (actual), 2 (plan) and 3 (commitment) are valid ?

  The SAP error message KA306 indicates that there is an issue with the overhead type being used in a particular transaction or process. This error typically arises in the context of controlling (CO) modules, particularly when dealing with cost centers, internal orders, or other cost objects.
  Cause:
  The error message KA306 is triggered when an attempt is made to use an overhead type that is not valid for the operation being performed. In SAP, overhead types are categorized as follows:
  
  Type 1 (Actual): Represents actual overhead costs that have been incurred.
  Type 2 (Plan): Represents planned overhead costs.
  Type 3 (Commitment): Represents committed overhead costs that are expected to be incurred.
  
  If you are trying to use an overhead type that is not one of these three (for example, a custom or invalid overhead type), the system will generate this error.
  Solution:
  To resolve the KA306 error, you can take the following steps:
  
  
  Check Overhead Type: Verify the overhead type being used in your transaction. Ensure that it is one of the valid types (1, 2, or 3).

  Transaction Context: Ensure that the transaction you are performing is appropriate for the overhead type you are using. For example, if you are trying to post actual costs, make sure you are using overhead type 1.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more information on overhead types and their appropriate usage.
  
  
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert who can provide further assistance.
