Need help regarding HCM process LOA

Hi Guys,

I am trying to implement LOA . Have some questions regarding the same. Please help me .

Is there any standard business object available. Is Bus object bus7051 anyway relevant to this.

Any std workflow or the task close to the process ?

And finally , at the end of the process what all the areas (infotypes) need to be updated.

Sincerely appreciate your help.

Rajesh.
