Hi
Lets suppose your are running on Oracle, you can change the threshold of change that fires statistics update update using BR*Tools parameter stats_change_threshold.
Check the here under note.
Please post in the appropriate SCN area (SAP on Oracle) you will have more answers and would not bother Moderators with moving your question.
Next time pay also attention to provide the DB you are running on with the version.
Regards
892296 - Enhancements in update statistics in BRCONNECT 7.00 / 7.10
as of Release 7.10 patch 22
stats_change_threshold = <threshold>
| (<threshold> [, all_part:<threshold> | info_cubes:<threshold>
| [<owner>.]<table>:<threshold> | [<owner>.][<prefix>]*[<suffix>]:<threshold> | <tablespace>:<threshold> | <object_list>])
Default: 50%
This new syntax enables you to define different statistical change threshold values for certain tables or table groups.
If, for example, you want to define a lower statistical change threshold value of 30% for the InfoCube tables than the standard value of 50%, which applies for the remaining tables:
stats_change_threshold = (50, info_cubes:30)

When you use BI process chains, we recommend that you include a step for the statistics creation. Note the following: New statistics are created only if the change threshold value (STATS_CHANGE_THRESHOLD) for BRCONNECT is reached. If InfoCube tables are changed, this may be problematic in some cases because even minor changes have a strong impact on the CBO behavior. In this case, you may consider taking measures: For example, you can lower STATS_CHANGE_THRESHOLD, include critical tables with ACTIV=U (general statistics creation) in DBSTATC or directly call BRCONNECT using the appropriate force options (for example, "-f collect").
