1. If the total check value from the manual execution is greater than the expected value of the total Check:
      1. Check if the objects involved in the total check are shared between several Analysis Units. For that run the following query on the central schema

        select  dso.object_id, dso.object_name, dso.object_full_name

                                count(distinct DLI.PREVIOUS_OBJECT_ID) as T_SHARING_FACTOR

                 and R.METRIC_VALUE_INDEX = 1
                 and R.SNAPSHOT_ID = HT.SNAPSHOT_ID 
                 join DSS_LINK_INFO DLI

                   on DLIM.SNAPSHOT_ID = HT.SNAPSHOT_ID 
                  and DLIM.LINK_TYPE_ID = 1

                 join DSS_OBJECTS dsot
                   on dsot.OBJECT_ID = dli.PREVIOUS_OBJECT_ID
                where R.SNAPSHOT_ID = <Snapshot_id>
                          and T.METRIC_Id = <Metric_id>
                group by R.SNAPSHOT_ID, R.OBJECT_ID
                        ) T

         or T.T_SHARING_FACTOR > 1

        Replace the metric_id with the metric Id of the Quality rule and the snapshot_id with the snapshot id from where the issue is observed. For the Quality rule Avoid using "SELECT DISTINCT", use DELETE-ADJACENT, the metric_id is equal to 7594:

        Following is a query result sample

        Query result example
        113422;"web.xml";"[S:\Sources\PPIT\Java\IdentityService\service\src\main\webapp\WEB-INF\web.xml]"
        Query result interpretation
         The query returns the object id, object_name and object full name

        If the query returns rows then there is Shared objects between Analysis units, the query returns the list of Shared objects

        1. Examine the configuration path of the Analysis Units and check if there is an Overlapping between paths, for more information refer to CMS - Analysis Unit editor

        2. Check if the Shared objects are part of the overlapped Analysis Units by Viewing Analysis Unit content, for more information refer to  CMS - Analysis Unit editor. you can use the following page to get the list of objects belonging to an analysis unit - SQL Queries - CAST Knowledge Base - Queries on objects - What is the Analysis Unit of an object or list of objects
          1. If the Shared objects are part of the overlapped Analysis Units:
            1. If the Analysis Units were configured manually, then this is an expected behavior.
            2. Else if the Analysis Units were discovered by the DMT then refer to Delivery Manager Tool Component DMT
          1. Else If the Shared objects are not part of the overlapped Analysis Units, then there is an issue with the Analysis Units creation, for further investigation refer to CMS Analysis Unit - Analysis Units creation

    2. Else If the total check value from the manual execution is lower than the expected value of the total Check:
      1. Get the list of objects counted in the total checks
      2. Run the TOTAL procedures manually on the knowledge schema by following the page SQL Queries - CAST Knowledge Base - Queries on metrics and diagnostics - How to run DETAIL and TOTAL procedures manually
      3. Identify the sub-query or condition of the procedure responsible for getting (depending on your initial observation) objects more or less than expected, You can proceed per identification by executing sub parts of the procedure. 
        If we take the example of the Quality rule Avoid using "SELECT DISTINCT", use DELETE-ADJACENT  that have the following TOTAL procedure:

        a condition can be the following condition:

      4. If the identified sub query involves the table ObjInf with the condition InfTyp = 9, then the issue occurred under the Metric Calculation, If so refer to the following page for further investigation CMS Snapshot analysis - Run Metrics Calculation

      5. Else if the identified sub query involves the table ObjInf with a condition different then InfTyp = 9, then the issue occurred under the Analyzer, If so refer to the following page for further investigation CMS Snapshot Analysis - Run Analyzer
      6. Else the issue occurred during Compute Snapshot then refer CMS Snapshot Analysis - Compute Snapshot
