Effect of SAP R/3 upgrade on Delta Queue

23 Views

Hi Gurus,

We have our SAP upgrade scheduled to go-live in some time. My problem is that we have 2 loads based on Direct Delta queue concept.

As per my understanding, the approach that we need to follow is that we should get all the users locked and then load the data into BW system from delta queue. Once this is done and the delta queue is cleared, we can bring the R/3 system down for upgrade.

The approach adopted for Upgrade is Downtime minimised, wherein for most part of upgrade, system will be down and for some part of upgrade the production will be up and running. In such a scenario where system will be up and upgrade will be running simultaneously, will there be any impact on the delta queues or rather shall I say that 'Will the delta queues affect upgrade process'
