Setting Up a Sub-Drilldown

Second level drilldowns can be very useful in cases where a critical number is calculated from sub-totaled data, and the details of the sub-total need to be accessible. You can use Output Column property names of the parent drilldown as input parameters for the sub-drilldown.

Setting up an IDO-based Sub-Drilldown

Follow the steps in Setting Up a Critical Number Drilldown Based on an IDO to create the drilldown. To associate the new drilldown as a sub-drilldown:

  1. Launch the Drilldowns Setup form.
  2. Navigate to the top level drilldown.
  3. On the Sub Drilldowns tab, specify the new drilldown and a description for it.
  4. Save the record.

Setting up a Sub Level Drilldown Based on a Stored Procedure

The preconfigured Inventory Value critical number is a good example of second level drilldowns for stored procedure-based critical numbers. This critical number shows your whole inventory value, and drills down to a subtotal by inventory. It drills down one step further to item totals or location totals by warehouse.

Follow the steps in Setting Up a Stored Procedure-based Critical Number Drilldown to create the drilldown. To associate the new drilldown as a sub drilldown:

  1. Optionally, use the @Parms parameters to accept filters into your drilldown.

    For example, the Inventory Value Detail Drilldown (SSSWBCanInvValDtlSp) accepts Whse in @Parm1, Item in @Parm2, and Location in @Parm3. It is coded to use these values as filters if provided, or ignore them if they are not provided.

  2. Specify Source Parms in sequence for how you want to accept your parameters in your stored procedure.

    When one drilldown calls another, the sub-drilldown automatically pulls these values by column header name from the calling drilldown. For example, the Item Inventory Value Detail drilldown has a Column Heading named Item. When it calls the Inventory Value Detail sub-drilldown, the Item value is passed to the Inventory Value Detail program in @Parm2.

  3. Launch the Drilldowns Setup form.
  4. Navigate to the top level drilldown.
  5. On the Sub Drilldowns tab, specify the new drilldown and a description for it.
  6. Save the record.
