Hi everyone!My question may sound 'dumb' for some but I'm really in doubt by now - regarding the installation of EHP4 on my system.I recently upgraded my Solution Manager to EHP1 in way to make it ready for EHP4 installation process but now I'm not sure which procedure I have to follow regarding EHP4 for ERP/ECC.I have found lots of notes and documents concerning the installation/upgrade of EHP4 for ERP 6.0 system but almost nothing for ECC 6.0. Part of those mention that ERP 6.0 is part of an ECC system - at least is that what I think I'm getting of it.Are ERP 6.0 and ECC 6.0 systems the same thing?In SMSY my system is registered as ECC 6.0 but all its software components are identical to an ERP 6.0 system - so it gets me 'confused'.Has anyone gone through the same situation?Thanks in advance for any help or tip.Kind Regards,PauloFYI: I'm running only an ABAP stack. Darkness at noon movie. Based on your situation, you should use the ERP 6.0 definition.This will avert any issues when you begin to use Maintenance Optimizer to define and select your stack.If you look closely at the document for Enhancement Pack 4 (I understand you are not there yet).

But just an FYI, there is an entire section that explicitly says:System is registered as SAP ECC 6.0, not as SAP ERP 6.0Issue: You do not get the option Enhancement Package Installation in SAP Solution Manager Maintenance Optimizer.Reason: Your system is not registered as u201CSAP ERP 6.0u201D in SMSY.Solution: As mentioned earlier in this document, the required product version is u201CSAP ERP 6.0u201D. The selection item Enhancement Packages appears in the Maintenance Optimizer only if you registered this product versionHope this helps.
