Installing support packs

Hi Guys

We are going for installation of support packs. We would be moving from level 31 to 55 for SAP HR 4.70 and from level 29 to 55 for EA-HR 110.

I need to identify HR objects impacted and do unit, scenario and process testing for analysing the impact.

My Question -

1. Where do I get the list of the objects that are impacted. I believe SAP should be giving a list of programs, FMs etc changed as a result of the support pack. How do I get that list?

Any other relevant information/doc/link will be most welcome.

And of course, points will be awarded.

Hoping for a positive response.

Regards

Lincoln
