Lock infotype 2001

[Jose Burgman]

Hi every-one
 
We want to create a leave workflow, using the ABSENCE object - the user
enters his info through PA61 IT2001 and saves. This must then be =
approved by
the manager. To get this to work, we would need to lock the infotype on
saving. I know some of the other infotypes one can lock for eg IT0008, =
but
I'm not aware of being able to do this with IT2001. Does any-one =
perhaps
have a solution?
 
Regards
