Issues you may face with Precalculation server patch 400 & Solution

The purpose of this blog is to explain some of the functional/installation changes you will see when you install precalculation patch 400 for SAP GUI 740 onwards.

From 740 precalculation patch 400  only one precalculation service file is delivered i.e SAP BW Precalculation Service Multi Instance.

Here I am explaining some new changes which you may observe after installation of 740 precalculation patch 400.

One of the Precalculation service file is removed from 740 Precalculation patch 400. i.e SAP BW Precalculation Service

Due to this change you may face some installation issues and functional issues related to removed service 'SAP BW Precalculation Service '.

If you face any such issues please follow the below information/steps

1. There is no concept of upgrade of precalculation from older version to newer version.

          Precalculation is only for direct installation.

          Please check the Precalcserver installation document which is delivered along with Precalculation server in SAP     GUI  DVD.

     2. In case you have upgraded precalculation server from older patch to latest patch
           Ex: 740 precalculation patch 300 to 740 precalculation patch 400            

Issue:

• You can still see two Precalculation service files. i.e SAP BW Precalculation Service & SAP BW Precalculation Service Multi Instance when you Goto Run -> Services.msc

as shown in below figure:

But as already mentioned above that from precalculation patch 400 only SAP BW Precalculation Service Multi Instance service file is delivered not the SAP BW Precalculation Service.

So the SAP BW Precalculation Service which you see in the list here is of older patch which won’t work.

• Now when you try to uninstall precalculation server to remove the ‘SAP BW Precalculation Service’ using precalculation server patch400 or from control panel, Though uninstallation get successfully completed ‘SAP BW Precalculation Service’ still persists in the services list.

Solution:

2. Install Precalculation patch 400.

      Now you would see only one precalculation service i.e SAP BW Precalculation Service Multi Instance.
