• What is the cause and solution for SAP error message GU987 - At least one ledger must manage a logical system ?

  The SAP error message GU987, which states "At least one ledger must manage a logical system," typically occurs in the context of SAP's General Ledger Accounting (G/L) and is related to the configuration of ledgers and logical systems in the system landscape.
  Cause:
  This error usually arises when:
  
  Missing Configuration: There is no ledger assigned to the logical system in the configuration settings. This can happen if the system was not properly set up or if changes were made to the configuration without ensuring that all necessary components are linked.
  Logical System Not Defined: The logical system that is being referenced does not have any ledgers assigned to it, which is required for proper data processing and reporting.
  Transport Issues: If you are transporting configuration from one system to another (e.g., from development to production), the necessary ledger assignments may not have been included in the transport request.
  
  Solution:
  To resolve the GU987 error, you can follow these steps:
  
  
  Check Ledger Configuration:
  
  Go to the transaction code OB22 (or navigate through the menu: SPRO > Financial Accounting > General Ledger > Master Data > Define Ledgers).
  Ensure that at least one ledger is defined and properly configured for the logical system in question.
  
  
  
  Assign Ledger to Logical System:
  
  In the same configuration area, check if the logical system is assigned to a ledger. If not, you will need to create or modify the assignment.
  Ensure that the ledger is active and correctly set up to manage the logical system.
  
  
  
  Review Logical System Settings:
  
  Use transaction code SCC4 to check the logical system settings and ensure that it is correctly defined in the system.
  
  
  
  Transport Requests:
  
  If the issue arose after a transport, check the transport request to ensure that all necessary configurations were included. You may need to re-transport the missing configurations.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to ledger and logical system configuration for any additional steps or considerations specific to your version of SAP.
  
  
  
  Testing:
  
  After making the necessary changes, test the configuration by executing the transaction or process that triggered the error to ensure that it has been resolved.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as OB22 (Define Ledgers), SCC4 (Client Administration), and others that may be useful in managing your configuration.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to this error message.
  System Documentation: Always refer to your organization's internal documentation for specific configurations and practices that may differ from standard SAP setups.
