Workbook Precalculation by Determine from Variants

We have a workbook including 30 queries which is developed in BW 3.x Analyzer.

These queries's varialbe selections are all the same.

In configuratio of information broadcast, we use determining from variants . The variant is saved on one of these queries.

If we run the workbook from BEx, that is fine.

The other queries could read the variable value from the variant.

But when using workbook precalculation, the value in the variant could not refresh all queries, and it just refreshes the query which the variant is saved on.

So how can I solve it ?

Thank you for your suggestion.
