Mismatching usage types for EhP4 upgrade

26 Views

Hello SAP,

We are planning to upgrade EC2 to EhP4 and I am currently in the process of choosing the technical usages in MOPZ.

I noticed that when I checked EC2's usage types from the link http://mdcsap01:50000/utl/UsageTypesInfo, i get the following:

- Process integration

- BI JAva

- Application Server

- EP Core Components

- Enterprise Portal

- Application Server ABAP

- Self services

- learning sol'n content player

- biller direct

- extended e-selling componentsa

- central component

- business packages (portal content)

when i compared it to the currently installed java components, they do not match. I mean, for example, I have the usage types Enterprise Portal and EP Core but i dont even have specific java components installed like EPBUILDT or EPBC. Below are my current java components.

- ADSSAP

- BASETABLES

- BI_MMR

- BI_UDI

- CAF

- CAF-UM

- CORE-TOOLS

- JLOGVIEW

- JSPM

- KM-KW_JIKS

- LM-TOOLS

- SAP-JEE

- SAP-JEECOR

- SAP_JTECHF

- SAP_JTECHS

- UMEADMIN

I mean, I think these components are basically for usage type Applicaiton Sever Java alone.

why is there a consistency? and which should i consider when choosing the technical usages for EhP4: my currently installed components, or my usage types? I was thinking that if i consider my currently installed components, can i deactivate the usage types that do not match?

please advise.

thanks,
