Outbound IDoc for GL posting using ACC_GL_POSTING

Hi,

I am facing problem while trying to distribute GL posting document using ALE. I want to use the message type ACC_GL_POSTING. But found that there is a BAPI for that message type. So I added the corresponding object. When I go to BDBG and checked the interface, everything looks good. But when I use the transaction fb01 to post and save data in the transaction, it is not sending any idoc. So is there anything else I am missing, so as to trigger the standard outbound function module associated with the BAPI.

Please let me know the steps to follow for distributing IDoc using ALE BAPI interface.

Thanks
