Relating "Education\Training" to "Institute\Location" in IT0022

In Infotype 0022 (Education).

Educational Establishment defines relationship with Certificates and Branches of study.

&

"Educational \ Training Categories" relates "Education and Training".

Now I have 2 queries.

1. If we can relate "Education & Training" with "Institute\Location".

2. "Institute\Location" is a text field, i need this to be changed to a drop down.(to avoid duplicate entries).

Need a Quick Reply.
