SAP R3 4.7 to SAP PI 7.31 connectivity

[Former Member]

Hi Experts,

we have a SAP R3 4.7 ( WAS 620) system which has never been connected to any PI system.

We have SAP PI 7.31 EPH 5 system ( Dual Stack)

We have interfaces running from SAP ECC 6.0 with SAP PI 7.3 .

Can anyone let me know if i can connect R3 with  just java stack of PI or it will support only ABAP stack?

Also can you please send me the list of steps for proxy connectivity?

Regards

Hi Biplab

I can confirm that proxy is possible from Web AS 6.20 onwards. I was involved in a project long time back integrating an R/3 4.7 system with XI 3.0 and we were using proxies.

Both Inaki's link above and the one below also mentions Web AS 6.20 as a minimum prerequisite.

Proxies in SAP - Netweaver Technology - SCN Wiki

As this was so long ago, I can't remember if the R/3 system had the XI2.0 add-on installed on it in order to generate the proxies. I'd suggest you try generating a proxy, and if it does not work, then get the add on installed.

One thing I do remember is for inbound proxies (XI -> R/3), the path for the target URL is slightly different and needs to be as listed below. The type needs to be "receiver" instead of "entry" which is what is commonly used now from Web AS 6.40 and above.

http://server:abapport/sap/xi/engine?type=receiver

As for connectivity using SOAP on Java stack only (ICO), I am unsure of this as this was long before Java only processing was available. An R/3 4.7 system does not seem to meet the prerequisites mentioned in the document Hareesh provided above. I guess there is no harm trying it out. I am sure that connectivity is supported on ABAP stack via the XI adapter, so you can always fall back on a classical scenario if ICO does not work.

Well, as the saying goes "you'll never know if you never try"

Thanks Eng.

Agree, SOAP with Java may not work.

I have dual stack so i can still use the ABAP engine.

Do I need to use port 8000 always and not 50000?

I am working on the connectivity... will let u know how it goes

It's the PI HTTP port. You can find it under smicm.

Hi Biplab,

Hope you are doing good.

Are you are that you have dual stack; they more or less ceased to exist after 7.00 release.

Most likely you have a standalone j2ee as PI or separate abap and java stacks .

Regarding ports:

Hope this helps

Hi Biplab

Note that the "type=receiver" part only applies to PI -> R/3 connection. For that connection, you will be accessing the service on the R/3 side so it needs to be the ABAP port. The port value depends on the instance number of the R/3 system. Therefore it will be 80xx where xx is the instance number.

You can always verify the port by going to SICF in R/3 to test the service:-

SICF -> Execute -> Navigate to "default_host/sap/xi/engine" -> Right click and test service

Thanks Eng.

We have only R3 to PI proxy not otherway.

And also we have dual stack

i saw the HTTP port is 50000

the issue i am getting when creating the RFC connection is

When i give the user id Password of PI system it shows below

uiltimately this error

Any clue?

Hi Biplab,

• Check have you maintain the user under logon & security tab
• The User must have the role SAP_XI_APPL_SERV_USER
• May be wrong password for the user you maintained in the destination.
• Check Accept Cookies option under Special Options tab, Select Yes(All)

Praveen.

Hi Praveen,

Please see the connectivity details

1. checked the password,user role

i dont see "Accept Cookies option under Special Options tab"....

Hi Biplab,

Hope you are doing good. The 401 Unauthorized error means the page you were trying to access can not be loaded until you first log on with a valid user ID and password. If you have just logged on and received the 401 Unauthorized error, it means that the credentials you entered were invalid for some reason. Please try with a "Administrator" user for testing purpose and see if this helps;
This will help us in isolating the issue.

Your screenshot above didn't show which user you have configured for the RFC. Usually we would use user PIAPPL<SID> which is created during the post installation wizard in PI. This user would have the role that Praveen mentioned above. Refer SAP library link below:-

Standard Users (AEX) - SAP Process Integration Security Guide - SAP Library

Thats a peculiar problem....  we are still unable resolve this issue

"Response from Webserver contains Cookies"

[former_member184720 · Accepted solution]

But you should not get unauthorized exception for this.

However, does your password has combination of upper&lower case.

AFAIK - password's are not case sensitive in R3 4.7.

If that is the case then you might want to define your password in lower case and maintain the same in RFC to see if that helps..

Hi Biplab,

401 unauthorised is user/permissions related issue. you can cross check them again.

Thanks and Regards,
