R3 upgrade and SAp Application's depedencies.

Hello all,

The following is on my mind.

We have an 4.6c basis + BW3.1(3.3cont) + MySAPscm4.0 landscape.

We are planning to upgrade the whole landscape, but due to capacity we cannot do the upgrade projects in parralel of eachother.

The first upgrade project we plan, is the upgrade of the 4.6C basis environment. We plan to upgrade this 4.6 environment to MySAPERP2005(ECC6.0).

And when we succesfully finish this upgrade we start on the next environment in our landscape, for example the BW environment.

My concern is, will we still be able to perform all daily-normal operations in BW and APO(mySAPSCM),dataloads and such, after the R3 basis upgrade?

This is because I understood there's no separate PI component in ECC6.0 anymore, will my connectivity between all the systems still work?

Pls respond if you have any ideas or experiences concerning this topic.

Kind regards,

Robbert van den Boom
