Hi,

Suggestion is to refer SAP help for details:

1)Synchronous: when you need realtime response, i.e. you accept order and want to give order number to customer then you will call Sync service.

2)Asynchronous: when you dont need realtime response, i.e. you want to replicate all orders from one system to another system.

3)Request Confirmation: you made a request and system confirm your request. i.e. Order data is supplied and order number is confirmation. Database will be updated.

4)ReadQuery: I guess you are refering to Query/Response pattern, You just want some information. No database will be updated.

5)Notification: It is another form of "QueryResponse" but user action required.

6)Information: It is another form of "QueryRespone" but NO user action required.

Answer following questions to determine which pattern you need.

Q1. Do you need response?

Ans: Yes: Sync pattern

Q1.1: Does any update required?

Ans: Yes: RequestConfirmation pattern.

Ans: No: QueryResponse pattern.

Ans: No

Q1.2 Does user required to take notice of response?

Ans: Yes:Notification pattern

Ans: No: Information pattern.
