Idoc serialization

Hi,

I have a Idoc to file scenario where I need to process the idocs to files in the same order as i get them from the ECC system.

If one idoc fails in XI (either in IE or Adapater Engine) may be due to some error in XI , all the following IDOCs should halt till the first idoc is processed .Once the failed idoc is processed,then all the rest have to follow automatically.

As I have no sender IDOC communication channel, I am not aware of configuring EOIO.

As this is urgently required,Could some one help me with a solution in achieving this?

Thanks,

Mahesh
