Question

I am converting xml to a flat file using BizTalk.

There is a limitation of the number for records that can be contained in flat file.
When this limitation is exceeded I need to produces a 2nd (or 3rd or 4th) flat file with the remaining records and each file never exceeding that maximum.

What is the easiest way to accomplish this?

Answer 1

What you need is this. The idea here is:

1. You debatch your envelope schema within your orchestration (by executing the receive pipeline) and thus gain control over the debatched individual messages, using Microsoft.XLANGs.Pipeline.XLANGPipelineManager.ExecuteReceivePipeline
2. You add the debatched individual messages, how many you want, to the send pipeline input messages using Microsoft.XLANGs.Pipeline.SendPipelineInputMessages
3. Finally, you execute your sendpipeline within the orchestration using Microsoft.XLANGs.Pipeline.XLANGPipelineManager.ExecuteSendPipeline and passing it your SendPipelineInputMessages and your destination flat file envelope schema.

Check this for more clarity on debatching in your orchestration.
