• What is the cause and solution for SAP error message FWTR066 - Prod. type cannot be used as underlying because more than one trans type ?

  The SAP error message FWTR066 indicates that a production type cannot be used as an underlying type because there is more than one transaction type associated with it. This typically occurs in the context of SAP's Financial Accounting (FI) or Controlling (CO) modules, particularly when dealing with production orders, cost centers, or internal orders.
  Cause:
  The error arises when:
  
  Multiple Transaction Types: The production type you are trying to use is linked to multiple transaction types in the system. This can happen if the production type is configured to handle different types of transactions (e.g., different cost elements or different accounting treatments).
  Configuration Issues: There may be a configuration issue in the production type settings or in the transaction type settings that leads to this conflict.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Production Type Configuration:
  
  Go to the configuration settings for the production type in SAP (Transaction code: OPL8 or similar).
  Verify the transaction types assigned to the production type. Ensure that it is only linked to one transaction type if you want to use it as an underlying type.
  
  
  
  Review Transaction Type Settings:
  
  Check the transaction types that are associated with the production type. You can do this in the configuration settings for transaction types (Transaction code: OPL1 or similar).
  If there are multiple transaction types, determine if you can consolidate them or if you need to create a new production type that is linked to a single transaction type.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to production types and transaction types to understand the implications of your configuration.
  
  
  
  Testing:
  
  After making changes, test the configuration by attempting to use the production type again to ensure that the error is resolved.
  
  
  
  Seek Help from SAP Support:
  
  If you are unable to resolve the issue through configuration changes, consider reaching out to SAP support or consulting with an SAP expert who can provide more tailored assistance.
