Dear friens
I need Help
Hi marcosengineerQV,
I would suggest to do the calculation in the load script level. Use this expression to create a new field in your fact table.
BTW, what is the data volume(number of records) and data size.
Hope this helps,
Bikash
Hi
The performance of the expression is also affected by the structure of your data model. If, in the expression, you are using fields from many tables, especially if the association goes through too many levels, the performace will suffer.
You can reduce the number of tables in your loadscript by mapping attributes into the fact table and denormalising others and your expression performance may improve.
Regards
