Help with Drillthrough Link – Child Report

Hi Anonymous,

Thank you for reaching out to Microsoft Fabric Community.

The issue is likely caused by missing URL encoding or case sensitivity in your drillthrough URL filters:

• When you drill through using group_nm = NENS or HCI, the generated URL might break if the value contains special characters like spaces or if it is not encoded properly. This cause the child report may receive an invalid or incomplete filter, leading to blank visuals.
• Also please ensure that the group_nm field is included in the Drillthrough filters section of your child report. This is needed for the drillthrough to work correctly, as it ensures that the necessary filter is passed from the main report.
• One quick fix is like wrap all the “SELECTEDVALUE(...)” expressions with ENCODEURL() in your DAX for example like
  ENCODEURL(SELECTEDVALUE(qms_tij2x_precalculated_data[group_nm]))
