error in creating BIA index after SPS upgrade

Hi BIA experts,

we got issues in BIA after our BI SPS upgrade (current level SPS18):

when wir try to create new BIA index for a cube (normal basic cube), we got error RSD_TREX121 (index type ICB). This issue occurs since we completed SPS18 upgrade.

Any help and feedback are highly appreciated!!!

Regards,

Sally
