Single file to multiple IDOC's (on Multiple R3 Clients):

Question

Hi,
We have a complex Landscape with multiple (4) businesses (multiple R3) instances and most common R3 --> DEV 4 instances with 5 clients each, QAS 4 instances with 2 clients each with some additional clients, PRD 4 instances with a client each and Training 4 instances with 2 clients each in the Landscape along with BW systems.
We are trying to implement standard MDM - XI - R3 distribution scenario. Only difference being MDM Production will be the Master distribution client and have to be distributing to all the R3 clients. For those who doesn't know SAP MDM - is Master Data Management Engine and within this scenario the output from MDM is standard XML IDOC file.
To achieve this syndication is being planned as MDM production to distribute files to 4 businesses to 4 file share folders. These files will be picked up by XI production and will be distributing(Creating IDOCs) on multiple receivers (R3 --> DEV, QAS and PRD) clients of the respective instances.
The one to one scenario is very simple to build MDM XML file from file adapter to R3 IDOC of IDOC adapter, but for our business it becomes one file to multiple R3 clients (IDOCs) on multiple R3 instances;
My question is: Is there an easy way to configure single file to mutiple R3 client IDOC receivers scenario? Also there might be additions and deletions of the R3 clients based on business requirements. Is there any proposed or already implemented procedure to achieve this complex distribution?
We have planned on trying to define a business system for each R3 client (DEV/QAS/PRD) and to have the integration directories configuration built for all the 47 clients that the data needs to be distributed. With IDOC Adapter is this the only way to go? Also, in future if there are additions or deletions of clients it becomes maintenance intensive and there won't be a quick way to stop the distribution?
Your time and input is appreciated.
Thanks and Regards,
-Raj.

Michal,
Thanks for your answer and FAQ.
I think I am confusing everyone with my long messages!
We already have XI DEV, XI QAS, XI PRD.
But business requirement for the global harmonization MDM scenario is that MDM PRD should be able to distribute the XML files (IDOC fields in GLMAST01 - IDOC format) to all the DEV, QAS and PRD (R3) systems in the landscape. For this distribution XI is used as the integration partner (File adapter picks up the XML file from MDM file share location and IDOC adapter creates an IDOC on the respective R3).
For this specific scenario though XI-DEV and XI-QAS systems are present they are available only for testing phase. After the scenario is moved into production, XI-PRD should be able to pick up the XML file from MDM and distribute it to all the DEV, QAS, PRD R3 systems.
Same file needs to be distributed to 20 DEV clients across 4 DEV instances, 27 QAS clients across 4 QAS instances and 12 PRD/TRN(training clients).
Yes, as you said in your answer earlier deleting a client from the distribution is removing the client from the receiver determination (and removal of corresponding Interface determination, sender agreement and receiver agreement).
Addition of a client for distribution is adding the client (business system) in receiver determination (and addition of of corresponding Interface determination, sender agreement and receiver agreement).
Do I have to maintain all the 59 (Clients from different systems) sets of config within the ID and all the systems in SLD of XI - DEV/QAS/PRD? Even if I do so, Is this the right way to go, defining all the DEV/QAS/PRD clients within all the SLD's of XI -  DEV/QAS/PRD?
I am not finding an easy way to architect this.
I appreciate your time and patience.
Thanks and regards,
