Number of times, I have seen on SDN where people is not clear what is the way to make their new ERP system with Enhancement Packages ready to use that includes installation, configuration in solution manager, EHP upgrade, Business Function activation etc.
In my this blog, I am not going to dive deep in technical sea of how to do things but only how to make yourself float on the sea. Once you will float on the sea, rest you will learn how to dive ![]()
When you install new ERP 6.0 system with Enhancement Packages either EHP4/EHP5/EHP6, you need to follow certian things to make it ready to use like:
1) Install ERP 6.0 EHP4/EHP5 system. If you install it as EHP5 system then after installation, your system will be on EHP5 in which SAP_APPL and EA-APPL (Central Application Components) will be on EHP5. So, after applying latest patches through SPAM/SAINT, you can use this system.
But in case of ERP 6.0 EHP4 system, this is not the case. When you install EHP4 system, then all netweaver components like Basis, ABAP etc. will be on 701 release but all ERP components will be on 600 release. So, this system is not ready to use. This system is called as ERP6.0 EHP4 Ready.
2) As of SAP Business Suite 7, you need to download all the packages from Solution Manager. So, if you want to upgrade your system or want to install patches then you need to configure MOPZ in solman.
All of this you can do in transaction DSWP and SMSY till solution manager 7.0 EHP1. But from Solution Manager 7.1 you need to use LMDB, solman_setup and solman_workcenter.
If you are not sure which technical usage you need to install on your system. Then Check SAP note 1165438 for EHP4 systems & SAP note 1324838 for EHP5 system and there are guides attached to this note which maps Technical Usage to Component and to business functions.
Note: Please make sure before installing any technical usage, discuss with your functional team whether they need it or not.
3) In case of EHP4 Ready system, where SAP_APPL and EA-APPL is on 600 release. You need to upgrade it with EHPi only. With this upgrade, you can combine upgrade of any other Technical Usage as well in case you want to use any other technical usage.
But this is not the case in case of EHP5 system as in EHP5 system, Central Application Technical usage (SAP_APPL & EA-APPL) will be on 605 release only. So, if you want to upgrade SAP_APPL & EA-APPL then you can do it through SPAM. And even if you want to upgrade any other technical usage then same you can do it from SAINT as well. You can also use EHPi but it is not mandatory.
Note: If you want to upgrade any Technical usage to EHP4/EHP5 level then stack xml file is mandatory for upgrade whether you upgrade it from SAINT or EHPi.
4) When you want to activate any business function then same you should in accordance to Business needs and after discussing with functional team. You can activate Business function any time and it does not effect existing functionality. However, it is recommended to activate business function first in sandbox/test system and after testing transport it to other systems.
There is one exception in EHP5 systems where version of SAP_HR component is 604 only while for other components version will be 605.
5) If you are using Solution Manager 7.1, then you cannot define any system manually in SMSY as you do in case of Solution Manager 7.0 with EHP1. There you should follow below procedure:
Hope you will have an idea by now how to proceed in case you install new ERP system to make it ready for use.
Cheers !!!
