What is hub deployment?

Question

In the description of the functionality limitations for SRM as Add On for ECC 6.0 SAP talks about hub deployment.
+"The following deployment and migration constraints apply:
·         SRM as an add-on to mySAP ERP 2005 does not support hub deployment.
·         SAP ERP 2005 with SRM as an add-on does not support any multiple backend functions for procurement.
·         It is not possible to upgrade or migrate from a separately-installed SRM system to SAP ERP 2005 with SRM as an add-on."+
What is hub depoyment?
Is there anywhere a more detailed description of the constraints regarding SRM as Add On?

Hi
<b>Please read the details below -></b>
Hub Deployemnt is a part of SAP ICH.  It is part of the SCM Suite. One application for your requirement is SAP ICH (Inventory Collaboration Hub). Besides you can also work with a report giving the supplier an overview. Via SUS you will not get the Reqs. Modification of SUS is pretty difficult and often not worth the effort. ICH is the supplier collaboration element covering tigher collaboration processes, like forecasting, kanban, order management; it supports the production process, but for e.g. does not cover invoicing. it is different than SUS, which focus on small suppliers without any systems inhouse and only offers order managmt.
It depends on the environment, if you need SUS or / and ICH.
In longterm the SUS functionalities are planned to be integrated into ICH forming
a new product called Supply Network Collaboration offering all collaborative
processes.
- ICH is part of the SCM Suite as well found under Collaboratio Suite
- Installed on a separate Box; from SCM perspective it also makes sense to
separate APO and ICH; nevertheless SCM is a one client environment, like BW
- Documents are available via SCM and Solution Manager; search in the
Marketplace
The ICH Purchase Order process is also intended for small suppliers - this is not a difference between ICH and SUS.
But ICH is only intended for purchase orders with a material.
Therefore the scenario is a deciding factor.
For indirect materials you are probably doing some purchase orders without materials, and these purchase orders can not be handled within ICH.
If you have only purchase orders with material items ICH can definitely be considered - and it is the tool for the future.
A drawback of ICH is the master data complexity and this should be considered/evaluated before choosing ICH.
