Hi,
>>How can i accomplish this, and is there a messaging pattern named after this scenario?
The pattern you are looking for is the resequencer:

I’d agree with Stephen’s comments about implementing this in BizTalk, it may be a bit trickey.
If you’r pretty advanced with C# or .net, you may want to look at building a file adpater that can read in the files in the specified order, and get them processed through the mesage box in that order (you may also need to build a sequential convoy to achieve this (check Stephen’s \”Convoy Deep Dive\” article on MSDN for info on this)).
To get started with a custom adapter, there’s a FileAdapter sample in the SDK, and also an adpater wizard available on gotdotnet to get you started with a new adapter project. Be aware that builsing adapters is a pretty advanced topic in BizTalk, be prepered to sink some time into it if you try…
