Use Data Preview to display the content of tables and SQL Console to perform ad-hoc SQL queries

You will learn

  • How to display the content of tables and views using Data Preview
  • How to perform ad hoc SQL queries using SQL Console

Prerequisites

  • You have generated the data for the relevant database table by running the transaction SEPM_DG_OIA_NEW (or program RS_EPM_DGC_HANA_NEW ).

The tutorial starts from scratch, based on tables of the SAP NetWeaver Demo sample EPM Model (you can find details in the SAP Community The NetWeaver Enterprise Procurement Model – An Introduction ), so you can repeat the tutorial on any SAP NetWeaver 7.5 system.

Step 1: Open the Data Preview

In ABAP Development Tools (ADT), open the database table snwd_so_inv_item by choosing Execute ABAP Development Object (or using Alt+F8).
This will open the Data Preview which will allow you to explore the invoice items table.

Step 9: Add a JOIN condition

Adjust the SELECT statement in SQL Console in order to get the payment status from the order header by doing the following: Add a JOIN condition for the table snwd_so_inv_head
NOTE: You may get an error. You will solve this in the next step.

The FROM portion of the query should look like this:

SNWD_SO_INV_ITEM join SNWD_SO_INV_HEAD
on SNWD_SO_INV_ITEM~parent_key = SNWD_SO_INV_HEAD~node_key
join condition
