Event management for 261 posting

Hi Gurus,

in our scenario we need to deploy an interface that should be triggered by the posting of the movement type 261 (Good Issue from Prod. Order).

As for what I know, the best option is to create a custom program that will be triggered by a dedicated event.

There's any standard event that the system raise up during the posting of a 261 movement type?

Thanks a lot,

Marco
