Hi folks,

    Hi Santhosh

    We just upgraded our system from BI 7.0 to 7.4 successfully and we have faced few issues as well which we were able to correct.

    The document below lists the issues faced in BI 7.3 upgrade,  but most of them are in 7.4 as well.

    Pre-upgrade

    There are very few activities from BI side pre-upgrade.

    BI Activities starts in Checks phase. Here we need to go the Tcode /N/ASU/UPGRADE to do some checks. The tcode clearly shows what should be done and why should we do that along with a description. There are basis activities as well.

    Once that's done, SPDD activity comes in Preprocessing phase, clearing delta queues before execution phase and SPAU activity in post processing phase.

    Below links gives you information about whats SPDD and SPAU. Please go through once and ABAP consultant should help you in these phases

    http://scn.sap.com/docs/DOC-47617

    While clearing queues make sure there is no entry for any application components in SMQ1. Then load the same into BI.

    You should delete the setup tables as well before the execution phase.

    Also need to check if there are orders in error status in SM13.

    Post upgrade

    Check source system connections

    Check if deltas working fine and reconciling with ECC

    If APD is existing, please check if the program is executed properly.

    Portal execution will have page not be displayed error. First link has the solution for that.

    Update Rules should be corrected to be compatible with BI 7.4. Loads will fail with an error. Solution is in the first link. Simple one

    You should apply the note 2042469 for 2LIS_1_I3HDR load failure and some more notes for load failures.

    You should configure SICF to activate the services related to metadata repository and Master Data maintenance.

    You should maintain entries in RSADMIN table for return code behaviour

    I have given most of what I remember. Incase if you face any issues, post it here. We can sort it

    All the best!

    Regards

    Hi Santhosh

    There are also two relevant notes from BW perspective:

    1879618 - Pre-upgrade measures for upgrade/update to 7.4

    458363 - Prepare in upgrade: Inconsistent InfoObjects + InfoCubes

    They are good for avoid errors with BW objects on the upgrade phases.
