Could not inquiry Accounting Events

Hi! I am trying to see the accounting events from the menu option Inquiry->Subledger Accounting->Accounting Events but I get the following error:

"Subledger accounting features are not available to the General Ledger and Subledger Accounting responsibilities. To access this feature, please use a responsibility that creates subledger accounting such as Payables or Receivables."

I'm using a custom responsability, that uses the standard menu FA_MAIN.

Could anyone help me?

Thanks!!!.
