Architecting, Solutioning & Scaling Complex Apps using SAP BTP Extension Suite(Blog2): Real Time CAPM Scenarios

[mohit_bansal3]

This is the 2nd blog of my Blog series on SAP BTP. In this Blog, I would be discussing about:

• Architecting the BTP Setup for the Green field implementations.


• Identify the right services and subscription based on the sizing and scalability

SAP BTP Configurations and Setup : Based on the Business Process / Requirement 

In the previous blog of this blog series, We have discussed about high Level Architecture for the Real Time scenarios which meets Business needs and these custom complex solutions will be developed outside the main ERP Core (S4HANA / ECC Backend).

Keeping same Architecture in mind, Let’s focus on below important considerations:

• Identification of various technology component


• Interaction between these technology components to and from for building overall Technical Solution


• BOM (Bill of Material) and Provisioning BTP Services  according to different environments / Subaccounts


• Sizing based on the business needs, Flexible enough to scalable to at any point of time.

SAP BTP Enterprise Account Setup:

As a first Step after acquiring SAP BTP Enterprise Account by the customer, needs to perform some basic onboarding steps which can be further understood with the below link https://discovery-center.cloud.sap/protected/index.html#/missiondetail/3019/3297/

More detailed information for the enterprise account , can be checked with below link

Technical Landscape for Sub Account for mentioned Real Time Business case:

Setting up right Account Model is most important activity which needs to be realize during architecting / Solutioning for the BTP.

In this Blog, I would not be discussing about how to setup sub account / directory etc. Please refer one wonderful blog by our mentor @Murli for understanding of Account Models in Details.

A Typical 5 Tier, Subaccount Model will be as follows:

Considering the above 5 Tier Sub Account Model Architecture, Below Configurations setup needs to be performed :

 

BTP Set Up and Configuration Steps

 

Sr No	BTP Set Up & Configuration	Dev	SIT	Pre Prod	FDR	Prod
1	Environment Account Setup Sub Account Creation Org Creation Space Creation	Yes	Yes	Yes	Yes	Yes
2	Connectivity & Destination Setup On Premise Destination   Destination for consuming Cloud API etc	Yes	Yes	Yes	Yes	Yes
3	Configure ADFS Server with IAS SAML	Yes	Yes	Yes	Yes	Yes
4	Configure ADFS as Identity Provider in IAS	Yes	Yes	Yes	Yes	Yes
5	Create IPS Tenant	Yes	Yes	Yes	Yes	Yes
6	Configure IAS transformation, connectivity to s4	Yes	Yes	Yes	Yes	Yes
7	User Role Set-up	Yes	Yes	Yes	Yes	Yes
8	User Creation (test accounts & actual user creation)	Yes	Yes	Yes	Yes	Yes
9	SSL Certificate set up	Yes	Yes	Yes	Yes	Yes
10	Cloud Connector Setup	Yes	Yes	Yes	Yes	Yes

 

sed on the high Level Architecture discussed in my previous blog, We have below major requirements :

• CAPM Application needs to be developed in BTP


• Workflow for Approval Process


• Attachments Facility


• Third party API Integration


• On Premise S4HANA/ ECC Backend Connectivity


• ADFS for user's  authentication


• Roles Set up

Keeping the same architecture in scope, Needs to have below services are required for BTP enterprise Account:

 

Service Required for above Architecture

Details for individual service can be found under SAP BTP Discovery Center

 

Sr No	Requirement Based on the Scenario Discuss	BTP Cloud Service Subscription / Entitlement
1	Central Launch Pad for User Accessing the Application	Launch Pad Service OR   Work zone
2	Development Tool	Business Application Studio
3	Data Base ( Staging Data in the BTP)	SAP HANA Cloud
4	Workflow Management in the BTP	Workflow Management Service
	Attachment Storage	SAP HANA Cloud ( In Memory )          OR   SAP Document Management Service  OR   Object Store
5	Cloud Identity Management (ADFS)	IAS ( Identity Access Service) IPS ( Identity Provision Service)
6	PDF Printing	Forms Service by Adobe
7	Background Job Execution	Job Scheduling Service
8	Application Log handling   Audit Log	Application Logging Service Audit Log Service
9	Deployment Cloud Transport from one Sub Account to other Dev Ops , Automate the Deployment	SAP Cloud Transport Management  Service   Continuous Integration and Delivery   (  understanding of Internal MTAR movement  )
10	Security / Connectivity(Backing Service)	Authorization & Trust Management   Connectivity Service   Destination Service

 

Next Steps:

I hope  I have discussed about the Real Time Business Scenario for

• Architecting the BTP Setup for the Green field implementations.


• Identify the right services and subscription based on the sizing and scalability
