Asynchronous to multiple synchronous calls

[Former Member]

Hi,

so far , I've only done simple scenarios in PI.

Now , I need to make an asynchronous call from ECC to PI and then in PI , I need to call three web services,

1) authentify

2) read data

3) update data

Where operation 2 only is called if 1 is successful and 3 if 2 is successful.

I need to use an Integration Process for this ??

Any good recommendations for this scenario ?

What do I use to manage the errors ... advise users that an error occured in the web service calls. I beleive you can use an email alert for this.

Yes. Integration process would be recommended as lot of error handling would be required here.

I beleive you can use an email alert for this.

Correct, you may use Control step of BPM. Send step configured with receiver mail channel could be used anywhere to send mails.

Hi Dagnino,

Yes it is possible. But as prateek mentioned there are more no. of chances where your integration might break. So rethink your design.

Also see this weblog:

Here instead of using rfc you need to use your webservice calls. So you will have 3 sync steps. Anyone may break. Also you can use trigger alerts from BPM itself. Please check this weblog:

Thank you for your answers.

Unfortunately , it is the provider (external company) which decides of the process to call their services...

There is only so much leverage we can use ...

Thanks.
