Administrator access to the SAP S/4HANA Cloud tenant is required to create Communication Users and Communication Arrangements.

​
Find your API host

The API host is where StackOne sends requests.

1

Work out the host

For Cloud Public Edition, take your Fiori launchpad host and add -api after the system ID.

  • Launchpad https://my123456.s4hana.cloud.sap/ui gives API host my123456-api.s4hana.cloud.sap
  • For Private Edition or on-premise, use the host and port your Basis team exposes for OData, e.g. s4.example.com:44300

​
Create the Communication User

The Communication User is the technical identity for API calls.

1

Create the user

Open Maintain Communication Users, click New, enter a User Name (e.g. STACKONE_INTEGRATION), click Propose Password (passwords need at least 20 characters and a special character), copy the password and click Create. The user locks after three failed logins.

​
Create the Communication Arrangements

Each API is enabled by a Communication Arrangement.

1

Create a Communication System

Open Communication Systems, create a system for StackOne and add the Communication User under Users for Inbound Communication with authentication method User Name and Password.

2

Create the arrangements

Open Communication Arrangements and create one arrangement per API, each using the Communication System above.

  • SAP_COM_0008 for Business Partner, Customer and Supplier
  • SAP_COM_0009 for Product
  • SAP_COM_0109 for Sales Order and Sales Order Simulation
  • SAP_COM_0120 for Billing Document
  • SAP_COM_0118 for Sales Quotation, SAP_COM_0119 for Sales Contract
  • SAP_COM_0294 for Sales Pricing Condition Records, SAP_COM_0134 for Customer Material
  • SAP_COM_0164 for Material Stock, SAP_COM_0108 for Material Documents
  • SAP_COM_0374 for Warehouse, Storage Bins and Fixed Bins, SAP_COM_0755 for Warehouse Stock, SAP_COM_0353 for Warehouse Orders and Tasks
  • SAP_COM_0008 is needed for the connection test; for the others, create only the arrangements for the APIs you use, actions for other APIs return 403
  • Private Edition and on-premise have no Communication Arrangements: activate the OData services and give the user PFCG roles that allow them
