EWM to GTS set-up

GTS Gurus

Looking for EWM to GTS set-up help. Need to know what we need to set-up with respect to

1. Partner mapping
2. Organization structure mapping
3. Document mapping

Need what needs to be configured in EWM as well

Any guidance specially on partner number mapping to FTO and Legal Units if it applies will be a great help.

What do we need to enter for BS Partner Role and what needs to be done in the next screen as well.

Thanks - Arvind
