Hey, gang - not too familiar with FA’s, so if anyone can point me to whatever I missed, it would be greatly appreciated. I’ve migrated the customer’s list of FA’s into the system (in Initialization Mode) and they are asking to dispose of some FAs in some older periods. However, when I attempt to do this, I get the “Book Period cannot be found in the system.” error in the Disposal Period field when using a date back in 2015 (as an example).

However, I do have book calendar’s set up going back to 1990.



That said, the system is only allowing the selection of open periods as dictated by the Master Financial Calendar which, as it stands, only goes back to 2022 as of now. They aren’t live, so I can always take a snapshot and reconfigure an earlier financial year and generate periods that way, but I’m curious if there is another way to generate additional periods from previous years that have not yet been generated. Any help will be greatly appreciated. Thanks!
