Dezhi Fiori/S4 configuration step-by-step

First of all, you'll have to read and understand the following diagram of our server landscape, make sure you understand the "2-bucket method", which is, our Fiori frontend server and S4 server are separated

Secondly, let's start from the standard SAP shipped roles.

Randomly pick a role SAP_BR_PURCHASER and copy to another Z role, let say, ZNPL_PURCHASER and assign to yourself.

In this role, you'll see it contains 4 of the SAP's standard catalogs

Then we go to checkout this specific catalog SAP_PRC_BC_PURCHASER_PO from http://s4fiorigw.efglobe.com:8080/sap/bc/ui5_ui5/sap/arsrvc_upb_admn/main.html

We do a filter on 'SAP_PRC_BC_PURCHASER_PO'

Compared the Fiori Launchpad, for example, we want to deal with 'My purchasing Document items'

If we simply click one of them, it links to the Frontend Webgui Tcode 'ME2M', which obvious is wrong. Since it should be pointing to the backend S4

So we tried to check what kind of configuration for this tile

Then we go to LPD_CUST to find the 'UICORE->PRC->PurchaseOrder-displayByMaterial'

So above means it defines as a transaction ME2M, to call from system Alias 'SAP_ERP_PRC'

Then we go ahead to create an RFC type 3 ABAP named 'SAP_ERP_PRC'

When we tried to click it again, it pop out the following errors

Before we were using Firefox, so if we change to the IE browser, similar error
