ISA R/3 4.0 with ECC6

Former Member

Can you connect an ISA 4.0 "R/3 edition" implementation to an ECC6 backend? Asking two differenet SAP employees has resulted in two different answers. One says, "no problem", the other says, "no way".

The SAP expert that claims this cannot be done insists that I must upgrade my ISA implementation from 4.0 to 5.0.

*Keep in mind, we are not currently using CRM in any fashion, nor do we have any plans to use it. We have a standalone ISA R/3 application hooked up to a R/3 4.6C backend.

Thanks in advance for any feedback...

Hi Toni,

This is great news! Thanks so much for the reply, this is extremely helpful to us.

We've been very worried about the risk of this not working since it's not an SAP-supported configuration, and we don't want to have to lump an ISA upgrade in with the already-big core upgrade. So this makes me feel better.

Thanks again, you've made my weekend!!

Hi Greg,

We are using unicode for ECC6.0.

We have no problems with ISA 4.0 and Unicode.

To get ISA 4.0 running on ECC 6.0, there are some changes in ISA 4.0 needed.

At some positions of the code the release of the SAP system is checked. Looks like this:

if (r3Release.equals(RFCConstants.REL46C) ||

r3Release.equals(RFCConstants.REL620) ||

r3Release.equals(RFCConstants.REL640) {

There you have to add the ECC 6.0 system like this:

if (r3Release.equals(RFCConstants.REL46C) ||

r3Release.equals(RFCConstants.REL620) ||

r3Release.equals(RFCConstants.REL640) ||

r3Release.equals("701")) {

(Surely better with the constants)

In our shop, we had only to change that at the class RFCWrapperUserBaseR3 . Maybe you have to do that on more than one class, i don't know.

One other really important point for ISA4.0 with ECC 6.0!!! :

- EHP4 for ECC6.0 is not only an enhancement package!! If you install EHP4, that will delete the transaction SU05.

So if you are using SU05-Users for your Shop, do not install EHP4 for ECC6.0 ! First migrate the users to SU01 users and after install EHP4.

Best regards,

Toni

hello Bryan,

We are using ISA 4.0 too with an ECC 6.0 without any problems. It's working.

Prashil / Toni,

For ECC 6.0, are you using unicode or non-unicode?

We just began a project to upgrade from 4.6c to ECC 6, and we're running ISA 4.0. We're getting mixed answers from different sources on whether we absolutely must upgrade ISA or not. (We would prefer not to.) One of the reports we got from a consultant was that ISA 4.0 has unicode compatibility problems, so we're wondering if either of you (who report it working) were using unicode. Please let me know.

Thanks,

- Greg

Hi Bryan,

In our scenario, we are using ISA R/3 with ECC 6.0 and it is working absolutely fine.

Intially we were at ECC 5.0, that also didn't make much difference to the ISA configuration, it works the same as it is now.

I would to better upgrade the ISA to 5.0.

ISA R/3 4.0 is not compatible with an ECC6 backend.
