In part 1 of the blog series the Discover, Explore and Testing of the SAP S/4HANA Cloud APIs (Read Planned Orders) was captured and part 2 the consumption of the Read Planned Orders API in a Fiori application was showcased. In this part, the Configurations on the SAP S/4HANA Cloud System required to access the Read Planned Orders API is showcased.

Pre Requisites

  1. SAP S/4HANA Cloud System (ref link for trial access )
  2. SAP Cloud Platform API Management ( ref link for trial access)

Configurations on SAP S/4HANA Cloud System

The blog explains the concept of SAP S/4HANA Communication, Integration and Authorization artifacts.  In this section, steps for creation of the communication system and user for Read Planned Order APIs is covered.

Note:- The user should have the role Communication Management and Extensibility for this configuration.  This role can be assigned via Manage Business User Fiori application.

Creation of the Communication User

  • Open SAP S/4HANA Cloud and then navigate to Communication Management tab.
  • Click on Maintain Communication Users.

 

  • Click on New to create a new Communication User.

 

  • Enter User name (say COM_104), Description (say Communication user for Scenario SAP_COM_0104) , Password and click on Create.

 

Creation of the Communication System

  • Navigate to Communication Management tab.
  • Click on Communication Systems.

  • Click on New to create a new Communication Systems.

 

  • Enter System ID ( say MRP_LOCAL), System Name ( say MRP_LOCAL) and click on Create.

  • In the host name provide the details of your S/4HANA Cloud system details.

 

  • In the User for Inbound Communication click on + to add in the Communication user details.

  • In the Select Inbound Communication User search and select for the Communication User (COM_104 as used in this blog).

 

  • Select the Authentication Method for the selected Communication User, say User Name and Password (for Basic Authentication) and then Click OK.

  • In the User for Outbound Communication click on + to add in the Communication user details.

 

Creation of the Communication Arrangements

  • To create the Communication Arrangement, details of the Communication Scenario is required. This information can be found on the SAP API Business Hub, under the Overview tab of the selected SAP S/4HANA Cloud APIs ( Read Planned Orders).

 

  • For the Read Planned Orders API, the communication Scenario is  SAP_COM_0104 and therefore from the drop down, select SAP_COM_0104

  • Enter Arrangement Name (say Material Requirements Planning) and then click Create.

 

  • Select the Communication System created for this Communication Arrangement (say MRP_LOCAL as used in this blog)

 

  • This would now create the Communication Arrangements required to access the Read Planned Orders API and all the APIs which are part of the communication scenario SAP_COM_104. Details of this is available in the Best Practices explorer.
  • Click on Save to persist the Communication Arrangements.

 

Now that the configuration on the SAP S/4HANA Cloud tenant is completed, the Read Planned Orders API from your SAP S/4HANA tenant can be managed via SAP Cloud Platform, API Management.  Management of the Read Planned Order API using SAP Cloud Platform API Management has been covered in the Part 4 of this blog series.
