Technology to be used for IDOC generation (ALE/EDI)

Hi All,

I have to send an IDOC to the integration layer TIBCO which in turn takes care of sending the IDOC to the third party system. I need your help in identifying the technology that can be used for the same. Based on which things, we can go for ALE or EDI. Kindly help me in understanding the two concepts and deciding the technology to be used in this case.

Best Regards,

Kumar.
