RSO2 error and no component and infoset

Question

I try to use RSO2 to create a data source, but when I select Applic. component, there is no MM(material management) component.
only PI_BASIS and BW component is there. so how to add MM component?
error 2: under "extraction from SAP query", I can't find infoset I defined in other R/3 SAP server.  in our BI server, when I choose query area standard, I can't find table EKPO and EKKO, that's why I go to another R/3 server and create my infoset query Z1 to link EKKO and EKPO table. so how can I use infoset query Z1 in BI server or any other setting I need to do to be able to find table
EKKO and EKPO in BW server?

Answer 1

I'm creating data source in BW, why need to go to RSA6 to create a MM component manually? I thought this should be auto. created.
The issue is: when I go to RSA9, I click "yes" for transport component hirarchy, it doesn't ask me to select MM or SD component.
after that  a node "ROOT" with child "Acounting"  is created, this is not I want
also, in RSA1, how would I know BI content add on is installed? I click BI content, it lists analysis process ,is it a add on?
what else should I do to have MM component?
My second error still not resolved, I'm asking how can EKKO, EKPO appear in SQ02 table selection of BI server?
