Prerequisites

You have a license for SAP S/4HANA Cloud and have a developer user in this system
You have installed SAP ABAP Development Tools (ADT), latest version, and have created an ABAP Cloud project for your SAP S/4HANA Cloud System in it
You are familiar with the concept of extensions to the SAP standard and with BAdIs in particular. If not, see the More Information section at the end of this tutorial
To test the BAdI: In SAP Fiori launchpad, you have the authorization for the app Process Purchase Requisitions - Professional, i.e. SAP_BR_PURCHASER

Intro

The administrator receives an welcome e-mail after provisioning. This e-mail includes the system URL. By removing /ui you can log into the SAP S/4HANA Cloud ABAP Environment system. Further information can be found Developer Extensibility: Connect to the ABAP System.

A Business Add-In (BAdI) an object-oriented enhancement option, a hook for an object plug-in. It enables you to implement enhancements to standard SAP applications without modifying the original code.

In these tutorials, SAP has already defined the BAdI enhancement spot, MM_PUR_S4_PR for the Fiori App Manage Purchase Requisitions – Professional, and the BAdI definition, MM_PUR_S4_PR_CHECK.

You then implement the BAdI in the SAP Fiori app as follows: 1. For the BAdI definition MM_PUR_S4_PR_CHECK, you create a container, known as an enhancement implementation - here ZEI_BADI_CHECK_PURCH_REQ_000. 2. You can then create one or more BAdI implementations - here ZIMP_CHECK_PURCH_REQ_000. 3. For each BAdI implementation you create an ABAP Class - here ZCL_CHECK_PURCH_REQ_000. 4. Within this class, you then create a method of the BAdI- here MM_PUR_S4_PR_CHECK~check.

The advantage of this approach is that you can group several related BAdI implementations in one enhancement implementation.

At runtime:

The user creates a purchase requisition.
The enhancement checks:
- the quantity of items ordered is 10 or fewer
- the date is 180 days or fewer in advance
If not, the application returns an error.

The application will look roughly like this:

Throughout this tutorial, objects name include a suffix, such as 000. Always replace this with your group number or initials.

Step 1 Log on to SAP S/4HANA Cloud ABAP Environment

—

Open ADT, select File > New > Other.
logon
Search ABAP Cloud Project, select it and choose Next >.
logon
Select SAP S/4HANA Cloud ABAP Environment, enter the ABAP service instance URL and choose Next.
logon
To log on, choose Open Logon Page in Browser, then choose Next. (Alternatively, e.g. if you have an admin user and a developer user in the SAP BTP Cloud landscape, you may need to choose Copy Logon URL… .)
logon
logon
Check your ABAP service instance connection and choose Finish.
logon

Your project is available in the Project Explorer.

Step 2 Create package

Step 3 Choose enhancement spot

Step 4 Create enhancement implementation

Step 5 Add `BAdI` implementation

Step 6 Create implementing class

Step 7 Implement code

Add the following code to the method implementation if_mm_pur_s4_pr_check~check..

ABAP
DATA ls_message TYPE mmpur_s_messages.
**
READ TABLE  purchaserequisitionitem_table  INTO DATA(ls_pur_req_itm) INDEX 1    .

IF ls_pur_req_itm-orderedquantity > 10.
  ls_message-messageid = 'DUMMY'.
  ls_message-messagetype = 'E'.
  ls_message-messagenumber = '001'.
  ls_message-messagevariable1 = ' Quantity limit 10'.           "Place holder
  APPEND ls_message TO messages.

ENDIF.

IF ls_pur_req_itm-deliverydate - ( cl_abap_context_info=>get_system_date( ) ) > 180.
  ls_message-messageid = 'DUMMY'.
  ls_message-messagetype = 'E'.
  ls_message-messagenumber = '001'.
  ls_message-messagevariable1 = 'Delivery date limit 180 days '.           "Place holder
  APPEND ls_message TO messages.

ENDIF.
