How I can choose conditionally parameter from multiple dependent combo boxes in SpagoBI

How I can choose conditionally parameter from multiple dependent combo boxes with subqueries and send it to a report?

I have a BIRT report which use a stored procedure which expect parameter @category_id The input should come from one of three combo boxes:

  1. Combo with categories level 1
  2. Combo with categories level 2
  3. Combo with categories level 3

When you select something in combo 1 combo 2 is populated executing subquery which depends on value from combo 1.

When you select something in combo 2 combo 3 is populated executing subquery which depends on value from combo 2.

If combo 3 has a selected value this is sent for parameter @category_id

If combo 3 has not a selected value and combo 2 has selected value this is sent for parameter @category_id

If combo 2 and 3 are not selected combo 1 is sent for parameter @category_id

Any idea how to do it?

You are going to want to use cascading parameters.

Set the default value to % (wild card)

Use a like Statement in your SQL Query, if 2 and 3 remain % then it searches for everything. If they are populated is searches for the specific value.
