Upgrade from BW 701 to 730 SPS8 with SUM 1.0 SP6 Patch8

Hello,

our productive BW system (701 SPS10) will be upgraded to BW 730 SPS8. I`m using the tool SUM 1.6 SP06 Patch 8.

During the PREPARE phases our users complain, that the system compiles during the execution of transactions. For example the most important BW transaction RSA1.

Is this behavior "normal" during the PREPARE phases?

Thank you in advance for your cooperation.

Regards,

Joe
