Is it ok to put varchar type column in fact table
We are using Oracle Business Intelligence Product Version 12.2.1.4.0.
Is it possible to create filter in column if we use just varchar type columns?
For now we try FILTER("dimensions_table"."varchar_column" USING ("dimensions_table"."varchar_column" = 'filter_value')), but it's not working.
If we use FILTER("facts_table"."double_column" USING ("dimensions_table"."varchar_column" = 'filter_value')) it works, but problem is that we want to show varchar type data in report.
We are not sure if it is ok to put varchar type column in fact table.
