Filtering FTR analysis to only cases with “Clear Invoice” activity

Hello team, We recently began implementing a First Time Right analysis for SAP ECC using the most recent template from the App Store. One item we noticed was that the KPIs included in the analysis all filtered to only cases that included the Clear Invoice activity: Affected Net Order Value: SUM(CASE WHEN PU_COUNT(VBAP, CEL_O2C_ACTIVITIES"."ACTIVITY<%= language %>,CEL_O2C_ACTIVITIES"."ACTIVITY<%= language %> = <%= clear_invoice_activity %> ) = 0 THEN NULL WHEN PU_COUNT(VBAP, CEL_O2C_ACTIVITIES"."ACTIVITY<%= language %> ) - PU_COUNT_DISTINCT(VBAP,CEL_O2C_ACTIVITIES"."ACTIVITY<%= language %> ) = 0 AND PU_COUNT(VBAP, CEL_O2C_ACTIVITIES"."ACTIVITY<%= language %>,CEL_O2C_ACTIVITIES"."ACTIVITY<%= language %> IN (<%=rework_activities%>) ) = 0 THEN 0.0 ELSE VBAP.NETWR_CONVERTED END) FTR Ratio: AVG(CASE WHEN PU_COUNT(VBAP, CEL_O2C_ACTIVITIES"."ACTIVITY<%= language %>,CEL_O2C_ACTIVITIES"."ACTIVITY<%= language %> = <%= clear_invoice_activity %> ) = 0 THEN NULL WHEN PU_COUNT(VBAP, CEL_O2C_ACTIVITIES"."ACTIVITY<%= language %> ) - PU_COUNT_DISTINCT(VBAP,CEL_O2C_ACTIVITIES"."ACTIVITY<%= language %> ) = 0 AND PU_COUNT(VBAP, CEL_O2C_ACTIVITIES"."ACTIVITY<%= language %>,CEL_O2C_ACTIVITIES"."ACTIVITY<%= language %> IN (<%=rework_activities%>) ) = 0 THEN 1.0 ELSE 0.0 END)*100.0 Id like to understand what the concerns would be with removing this statement and considering all cases instead. I ask in part because we are having a problem with the Clear Invoice activity pulling in consistently, but also because we would want to include items that never go through that activity (such as cancelled orders). Can you help me understand why the Clear Invoice filtering logic was included on the First Time Right analysis provided by Celonis? Thank you!
