Query on Enhancement Pack Upgrade/ Installation-Business Functions install

I am working on an Enhancement Pack Upgrade. I have the following questions from the Client, can you please help answer u2013

Scenario u2013 Upgrade from ECC 6.0 to ECC 6.0 EhP4

1 Using Business Function Prediction service, assume SAP recommends 10 Business functions to be installed. We install the 10 business functions and after 6 months the client realizes that there are some more functions which will help business.

a.What does it take to install the additional business functions.

b.Do we have to do the entire EhP4 Upgrade again

c.If we have to do the entire EhP4 Upgrade again what happens to the initially installed business functions, will that be overwritten

d.What will be the additional SPDD and SPAU effort to activate the additional business functions, will that be same as the initial SPDD/ SPAU effort.

2 Can we install all the Business functions available in EhP4. What happens if we install all the business functions. What will be the additional effort or overhead in terms of hardware, database, ABAP effortu2026..?

Thanks in advance.

    Hi,

    1. For installing additional business functions you need to again run the whole EHPI process. But what I feel is even you install more than 1 business function you will be able to activate only 1 business function per system.

    2. The initially installed business functions would not go anywhere. You need to select them in your solman before the stack.xml file generation.

    3. SPAU/SPDD effforts depends on your system. So no comments.

    4. If you plan to install all business functions then you will need good amount of DB space and your upgrade downtime would be high.

    • I can only speak about technical usages. In note 1165438 you can see a mapping between business functions and technical usages, also between technical usages and components. Usage types are the Java terminology and I think I heard that they have a slightly different model than the technical usages in PPMS.

      Anyway, note 1165438 might help if someone knows a business function they want to install but cannot figure out the technical usages that is translated to, when working with Maintenance Optimizer.

    Hello,

    it does not make much sense to install all new functions or the 604 versions of all ERP components. One should plan what one needs and install only the needed components. If later on the requirement of new EHP4 functions arise one can easily install the missing 604 component versions with EHPI or SAINT. The SPDD/SPAU effort is restricted then to these additional components.
