Updating Choice is Gray in activating the Info Structure

[Former Member]

Hi Eduardo and other SAP Gurus,

I have created my new Info structre and I have done everything possible. But I am not able to choose the Updating.

Please guide how can choose as Synchronous or Asyncronous.

Thanks,

Go to MC25 and check whether you have generated the table before saving it.

I was facing the same problem myself yesterday .. Generate the table and then save it ...it will then not be a greyed out area..

Hi Jans,

V1 - Synchronous update:

If the SIS update fails, the OLTP document (example: Billing document) will not be saved!

On the other hands it guarantees that the update will take place.

V2 - Asynchronous update:

If the SIS update fails (for example because of an incorrect SIS formula), the OLTP document will still be saved.

My recommendation for SIS update : V2 update: You would not have to explain to your boss that this sales order / delivery / billing document was not saved because of its statistical update did not get through!

Dear Franck,

Thank you for your reply. But I am a bit confused. I will be grateful to you if you kindly elaborate the following comments for my clear understanding:

"My recommendation for SIS update : V2 update: You would not have to explain to your boss that this sales order / delivery / billing document was not saved because of its statistical update did not get through!"

Yes, I have done V2 but how can I tell my boss that this "sales order / delivery / billing document was not saved because of its statistical update did not get through!"

What is the difference between Synchronous and Asynchronous Update?

If you do V2 then you are fine, on the other hand in case you do V1 you might have to explain your boss that an OLTP document did not get saved because of SIS update failure.

IMHO OLTP is critical, so even if the SIS update fails, you want to save the sales document.

For a more technical answer, do a Google search on "LO-Cockpit V1 and V2 and V3 update", there you will find the information you need.

When several events happen at the same time, it's called "synchronous". "Asynchronous" is kind of an opposite, i.e. the events are not happening at the same time. Franck has already explained it quite well, so I'm not sure what's not to understand there, but let me just give an example.

For example, you have configured an info structure that is updated from the billing documents. When update is successful, it doesn't matter whether you've chosen synchronous or asynchronous - they both will happen and time difference will be only a few milliseconds. The difference starts when, for some reason (e.g. a data lock or inconsistency), the info structure update cannot be completed. What will happen:

1) You've chosen synchronous update:

- the billing document will not be saved ('Update termination' message will be displayed and there will be a record in SM13)

- info structure will not be updated

2) You've chosen asynchronous update:

- the billing document will be saved, as usual

- info structure will not be updated

With option 2 you'll at least have the document itself. With option 1 you'll have nothing.

I agree with Franck and would recommend synchronous update only when it's absolutely necessary. But your decision should be based on your business requirements.

Hi,

Use Tcode OMO1 to maintain updating.
