IDOC not coming in status 30 for collecting idocs

Hi All,

We have a requirement in which we need to collect idocs and send together.

To achieve I am making Collect idocs in Partner profiles so that it goes in status 30 and hence I can run program RSEOUT00 to make it status 03 and hence write in file as a group of idocs.

Now inspite of making collect idocs in partner profile, its not coming in status 30 but directly coming in status 03.

Please let me know what may be the reason for the same.

Thanks,

Vivek
