SAP PI - MII

[Former Member]

Hi I am looking for information integrating SAP MII with PI. The landscape is that PI should be between ERP and MII.

I am also interested in the architecture of this integration, ie. what typ of messages., SOAP call etc...

thanks

Sengkiang,

have a look at these threads:

Hi Michael

Thanks for the link. It is very usefull.

Does it means that if I (MII / or other systems) want to connecto to ERP via PI, they have to speak in SOAP protocol and PI translate them to RFC call?

Unclear for me is that can MII speak to PI with other protocols (RFC, BAPI ) and PI knows that automatically and transfer it to ERP and vice versa?

thanks

Sengkiang,

PI has a lot of build in adapters. You may use SOAP, HTTP, RFC or IDocs to send messages to PI (there would be even more).

In MII however there are two actions explicitly built to communicate with XI (PI). See [SAP Help on SAP Netweaver (MII 12.0) XI|http://help.sap.com/saphelp_xmii120/helpdata/en/44/83897e697e053de10000000a1553f6/frameset.htm] or [MII 12.1|http://help.sap.com/saphelp_mii121/helpdata/en/43/e80b59ad40719ae10000000a1553f6/frameset.htm].

In PI, you have to create an interface that receives the MII message and sends it to ECC. It is not automatically created. You will have to create the interface in two places (MII and PI). MII do not need PI to connect to ECC, but you have to use PI, right?

Hi Michael

Thanks very much, this give me more idea of PI now.

Do you know if is there any documentation talks about PI specifically? For example administrating PI, viewing messages in PI, and configuring PI?

If I understand your last message correctly, you are saying that

1. Integration of PI to ECC uses RFC, IDoc Bapi

2. Integration of PI to MII uses SOAP and HTTP

Of course PI is message bus, and could support other interfaces but above scenario is typical ECC - PI - MII ?

thanks again

Sengkiang,

concerning the PI, have a look into SAP help: [SAP Netweaver PI|http://help.sap.com/content/documentation/netweaver/docu_nw_pi_design.htm].

For your planned scenario MII - PI - ECC you would typically use

- MII - PI: HTTP, SOAP or RFC

- PI - ECC: RFC, BAPI, IDoc

Have you already planned which MII version to use? MII 12.2 has just started the ramp up, maybe this is interesting for you?

Hi Michael

We are using MII 12.1 and what are majors changes in MII12.2?
