Message type HRDM_A in eRecruiting

Hi gurus!!

We are implementing our eRecruiting system outside of our HCM system. The type of message we need to use is HRDM_A because of the infotypes we need to transfer via ALE. But when we verify in our eRecruiting system, this type of message doesn't exist.

I have two questions:

- Can this type of message be used in eRecruiting?

- How can we import a standard message type to our system?

Thanks in advance!!
