BTP Mistake Notes

Question 1

Exception subprocess?

Answer 1

Handle errors during main filow
500,mapping,timeout,connectivity errors
Setup Alerts:Write to message log,Send alert(mail,webhook,Event mesh)store failed message in data store

Question 2

Can we have multiple exception subprocess in single iflow?

Answer 2

No

Question 3

Activities used in Exception subprocess?

Answer 3

Content modifier,Message processing logs,Receiver adapters(Mailhttp,event mesh)data store write

Question 4

Exception subprocess for synchronous?

Answer 4

Yes,it can send response back to sender, Ex:Content modifier

Question 5

Realtime: How do use exception subprocess?

Answer 5

Successfactors to S/4 Hana integration: We use to capture API failures,Log emp id,payload,send alerts via mail,store failed message in data store for reprocessing.

Question 6

Exception subprocess handle adapter level retry?

Answer 6

No, It handles only post failure logic.no adapter retry mechanism.

Question 7

Webhook

Answer 7

It is an event driven mechanism, which automatically pushes data from one system to antoher system

Realtime: Instead of polling, use webhook

(Webhook: “I’ll call you when I’m ready”)

Question 8

What is Webhook in SAP BTP

Answer 8

it is an HTTP end point exposed by CPI

Registred in source system (Successafctors,Ariba,3rd party SaaS)

It automatically invokes when an event happens

Question 9

Where webhooks are used in CPI?

Answer 9

Successfactors->CPI
New Hire, employee update,Termination
SAP Ariba->CPI
PO created,Invoice approved
3rd party SaaS -> CPI
Payment success, Order created

Push based, No Polling,

Question 10

Realtime: Webhook

Answer 10

Successfactors sends new hire event,it sends employee data to webhook to CPI
CPI validates payload and push to Event Mesh
Multiple systems: ex: S/4 , Payroll,Analytics subscribe to the events and asynchronously

Question 11

What is Process call?

Answer 11

Used to trigger another Integration process(Local Process call)

Its a function call inside iflow

Question 12

Process call can be used for error handling?

Answer 12

No, It is only for reusing the business logic

Error handling can be done using Exception subprocess

Question 13

Process call vs Process Direct?

Answer 13

Process call: Invokes local integration process with same iflow
Process Direct: It is an Adapter , used to call another Iflow synchronously

Question 14

Why enable cloud foundry?

Answer 14

It is primary runtime environment,without enabling it, BTP services does’nt work
Ex:CPI,Event Mesh,APIM,Build apps,HANA cloud,Alert Notification

Question 15

Process call?

Answer 15

Used to invoke local integration process from main integration process

Question 16

can we call Local Integration process (LIP) multiple times in single iflow?

Answer 16

Yes

Question 17

Proces Direct?

Answer 17

Synchronous Adapter - Used to call another iflow inside the same CPI tenant

Same Tenant, No external call

Used when same logic used in multiple iflows

Question 18

ParallelMulticast?

Answer 18

sends the same message to multiple receivers at the same time (in parallel)

Question 19

What happens if one message fails in Parallel Multicast?

Answer 19

The entire multicast fails

Question 20

Content Enricher

Answer 20

Also called lookup message

used to add, modify, or enrich message content by calling an external sy

Question 21

Call->External call

Answer 21

Content Enricher & Request Reply
