SAP GUI relationship map

Hi all,

any idea if SAP GUI has the option of the relationship map for purchasing?

I have hundreds of questions about this version of SAP as I used to work on Bussiness one

- inventory master data - can I see list of all the items and every w/house

- how do I find all the open orders

- how to see all the orders placed against the vendor

- how do I find a list of items purchased from supplier

- can save PO's as a PDF as at this point we are printing and then scanning

Let's start with that, appreciate your help.

Thank you all

Kamila
