Hello,

Where can I find a list and description of FA SLA sources?  We are customizing FA SLA Accounting Rules and would like to know what sources we can use.  In the Create Accounting Rule form, the Source field shows a list of values.  It will be great if we can see a description of each.  For example, Source =  "Default Expense Account".  Does this refer to the FA clearing account?

Thanks
