SRM 7 ehp1 with ECC 6 ehp5?

[Former Member]

Gurus,

Is it mandatory to use SRM 7 ehp1 with ECC 6 ehp5? Our client has ECC 6 ehp 4 and is now upgrading from SRM 4 to SRM 7 ehp1. Can you share some links where I can confirm if SRM 7 ehp1 with ECC 6 ehp5 is mandatory?

Also pl let me know what is the difference between shopping cart creation in SRM 4.0 and SRM 7.0 ehp1. SAP says they have changed something and made it more user friendly. Is it different from normal SRM 7 (without the ehp component?)

John

Hi John,

From follwing solution browser URL, you can find the new feateres etween the SAP SRM older version and current release verions. Even you can export the details and dig in deep.

Thanks Krish.

But can you pl clarify if SRM 7 (Ehp1) would need ECC 6 (Ehp5) as a backend?

Hi John ,

For SRM 7 (Ehp1) there is no need to have ECC 6 (Ehp5) , you can use ECC 6 ( EHP 4) .

Thanks & Regards

Hi,

There are 3 ways of sending PO from SRM to ECC

1.Via - RFC ( by setting the system landscape to a lesser version ) it will not have any side effects just that it used RFC connections instead of ESOA

2.Via PI - by setting  the landscape to the current version and configure the relevant XML services in the SOAMANGER

3. via Non PI Web Services- by setting the landscape to current version . This time the webservices are configured in SRM system itself.

I have configured transfer of Contracts from SRM 7.01 to ECC 6.5 EHP5 as Contract/ Scheduling Agreement to the backend with Non PI Web Services(via XML). This way we didnt have to install PI at the client place which saved them a lot.

I have written a blog on how to transfer central contracts from srm to ecc using web services but without PI , please find the link below and hope it is helpful.

Hello,

No, it is not mandatory. You can have SRM 7.01 with ECC EHP4.

ESOA functionality is already available in EHP4.

I hope it clarifies.

Thanks everyone.

Okay my last question is: How does the PO creation in ECC take place in SRM 7.0 (ehp1)? I read it is via XML. Can you shed some light on the exact process, what business functions to activate? Also will PO creation in ECC (extended classic ) require XI as a middleware?

Can you direct me to a document which explains this process?

Regards,

John

HI,

If you using SRM 70 and above the PO creation from SRM to ERP will always be via xml as it is now using ESOA services.

As xml is used PI is not mandatory. There is no specific configuration required as xml is created why the proxy service called from the program.

SRM 7.01 to ECC 6 EHP4 uses ESOA. If you wish to not use PI, set the backend system type in 'Define System Landscape' to older version. It will continue using RFC's to send PO's.

Hey SG,

So does this mean PO creation with SRM 7.01 and ECC 6(ehp4) in my system landscape settings will need XI? Or will the XML PO be posted via some proxies?

You need PI/XI in XML ESOA communication.

You could use ECC6 EHP4 without PI by setting backend system type to older ERP version in SRM Define System Landscape configuration. But, you would lose the benefits of ESOA.

SG,

I don't intend to lose out on using EHp4 features. Assuming I setup my system landscape using new ECC 6 Ehp4, will this definitely need XI to even create a backend PO? I thought PI would only be needed for Central contracts and SUS deployment.

Have you worked on this landscape before or have you read it somewhere? Even Sam has said above in the thread that PI is not needed!

John,

I have used SRM 7.0 wth PI in the past with Plan Driven Procurement and I remember it sending PO through XML messages via PI for services. For self-service procurement it may just be calling the Proxy and sending XML without PI. I am not 100% sure on that.

Hi ,

I am sorry I have missed typed the information. If xml is used PI is mandatory. I am really sorry for this.

Also if you lower the ERP type in define system landscape system will still create xml for PO creation. Hence if you use SRm 70 or higher PO creation will use xml and PI us mandatory. I have worked on SRM 70 and SRM 70 EHP1 landscape.

I am sure about this behaviour.
