Insight Explorer - KPI from Knowledge Model cannot be added

Hi everyone,

I have a question relating to the Insight Explorer and look forward to your help/ advice.

In the related Knowledge Model, I have defined a KPI called Rate of transferred calls - ID =percentage_of_transferred_calls, with this PQL formula:

KPI("count_of_transferred_call_segments")
/
KPI("count_of_calls")

Unfortunately, this KPI does not come up on the list of Metrics that can be added to the Insight Explorer. If I search for its ID within the Insight Explorer configuration, I get the response:

No Metrics found

For additional context, count_of_transferred_call_segments has this PQL formula:

sum(
  CASE
  WHEN "ECHI_CASE_TABLE_Call_Data"."transferred" = '1'
  AND "ECHI_CASE_TABLE_Call_Data"."disposition" = 2
  AND "ECHI_CASE_TABLE_Call_Data"."outbound_call" = '0'
  THEN 1
  ELSE NULL
  END
)

While count_of_calls has this PQL formula:

SUM (
  CASE
    WHEN "ECHI_CASE_TABLE_Call_Data"."disposition" = 2
      AND
    "ECHI_CASE_TABLE_Call_Data"."outbound_call" = '0'
    THEN 1
    ELSE 0
  END
)

I’d really appreciate your help in resolving this issue. Thanks a lot.

Kind regards,

Vladimir
