Multiple instance of SAP Database 1

[Vic88]

Hi All

The parent company of my employer is in the process of installing SAP. The installation will be done at the company's HQ in Maimi. Users at my location will connect to the system via a T1 line.Sometimes there are communication outages between both locations and this caused serious concern about the downtime we will experience whenever this happens after the SAP go live

My supervisor has mandated me to find out whether SAP allows for the installation of an instance (or whatever it is call) at our location, that will replicate with the installation at the Miami Head office.

I am having difficulty getting any information from the fellows working on the project as the project manager is based at the Miami office and he wants to have total control over the system. Hence he has instructed to consultants not to answer any question relating to this.

Any advice via this forum will be highly appreciated.

Hi Vic,

I think the answer will depend on what exactly you would like to replicate.
Afaik SAP does not offer a way to replicate a complete SAP R/3. However there is a feature called 'Master Data Replication', and other kinds of partial replication. Other SAP products like KW (Knowledge Warehouse) may be replicated as a whole, I think.
But I don't work with these things on a regular basis.
Do you have an account at service.sap.com? If so, you should find a lot of info there.

Hello Vic88,

He had the same requirement for a SAP HCM solution (Human Resources), and there's no good replication solution for this module.

I think that the difficulty of the integration will depend on the modules you are going to use and specially on the amount of information to exchange between the systems, because there's no standard "consolidation" method between two sap systems. Logically, this replication should be made at the application layer to preserve data consistency, and sap is not prepared for this kind of operation.

If your system can be very independent and only has to exchange a little portion of the data with the parent company, you could use asyncronous tRFCs or similar to echange information.

But if you are looking for a complete syncronization between the systems and the same data can be modified on both sides, information collisions, error handling, etc...could be impossible to handle. Even if you can separate the data types to be modified on each system, you should probably have to build very complex interfaces.

Yours,
