FI-SL contains the following tools to help you improve your system performance and setup:

Set maintenance is also available as an FI-SL tool. For more information, see
Sets.In Customizing for Special Purpose Ledger, you can also use tools for checking, transporting, validating, substituting, deleting, and comparing data. For more information, see the Tools activity in the Implementation Guide (IMG) for Special Purpose Ledger.
Diagnosis Tool
You use the diagnosis tool when you want to test your system setup and determine how and where a document is posted or has been posted to the FI-SL System. You can then also check why a specific document is not posting to a ledger.

For a specific combination of document number, company code or company, and fiscal year, you can use this online function to check to which ledgers the document posted or will post. You can also check to which ledgers a specific activity (such as RFBU for FI postings) will post to FI-SL.

You can directly access the configuration settings while testing if a document would be posted to a ledger based on the data that you enter using the Posting test function. If the document would not be posted, the system displays an error message explaining the cause of the error. When you double-click the error message, you can display the long text for the error message. From this screen, you can directly access and change the applicable configuration settings so that the document can be posted to the ledger.
This function is only available when you test the posting for a specific ledger that has not been posted to.

Using the Diagnosis Tool.Control Report Tool
You can use the control report tool to display and/or print the contents of the FI-SL posting tables (ATAB tables). FI-SL posting tables are defined in Customizing. These tables control how documents are posted in the FI-SL system.

Once you have completed your system settings in Customizing, you can use this tool to check the settings.
