Reporting on hierarchies


Use the All Hierarchies (flat_hierarchy) table to report on relationship hierarchies and to track changes within health systems. The table displays all of the relationships and levels so you can see how HCPs and HCOs rollup to HCOs.

Note: You do not need to have the Hierarchy Explorer widget enabled to use this feature.

Relationship tables

The parenthco table can be used to view each entity and its direct parent HCO. You can create a SQL query and join the table with other tables, but this can be complex. Using the flat_hierarchy table, you can view all the relationships and understand how HCPs and HCOs roll up to direct and indirect HCOs.

Example - parenthco table

The report displays each entity and its direct parent HCO.

Example - flat_hierarchy table

For the HCP, Adam, a row is populated for every HCO that he's connected to so you can see all the relationships and the levels to understand how he rolls up to each HCO.


  • Explore targets - Find the HCPs in a specific health system or understand the health systems you should target for specific therapeutic areas. For example, you can produce a report for health systems that have a large number of HCPs that are gastroenterologists.

  • Maintain hierarchies and tracking changes - Compare old versions of your custom hierarchy to the new version to find breakages. You an also use it to understand how data source updates impact the hierarchy. For example, if a data source inactivates an HCO, you can see how that change impacts a hierarchy.

  • Roll up sales and interactions to the health system - Allow analytics teams to easily roll up the interactions and sales data to the health system or hospital.

  • Skip levels of the hierarchy when reporting - Data Managers and analytics teams can skip levels of the hierarchy using SQL.

  • Export to data warehouse - Export the report to your data warehouse so you can use it for business purposes like incentive compensation. This can be done using transformation queries.

Manage the table

The All Hierarchies (flat_hierarchy) table is available by default and can be managed on the Hierarchy Management page. You can also create custom hierarchies to use in the Hierarchy Explorer widget and in reporting.

  • To manage hierarchies click Data Model > Hierarchy Management.

Flat hierarchy tables are also available for OpenData instances that you have access to. For more information, see Reporting on OpenData.

Supported hierarchy paths

The flattened hierarchies support HCPs, HCOs, and ParentHCO relationships.

The report displays only active and valid relationship paths. Paths that do not meet this criteria are removed from the hierarchy.

  • Inactive paths - Paths are considered inactive for the following reasons:

    • HCP or HCP - Record status is not Active, they are candidate records, or HCPs have been opted out.

    • Relationships - The relationship status is not Active.

  • Invalid paths - Paths are marked as invalid for the following reasons:

    • HCP/HCP - Record state is not Valid or Under Review (Invalid/Merged_Into/Deleted) or the record is unsubscribed (record state is Deleted).

    • Relationships - The record state is not Valid or Under_Review or the parent of the relationship is not in your Network instance.

Shortest path

The shortest path between two entities displays in the report. Duplicate short paths do not display to prevent duplicate entities in roll up counts.

Example 1

Between Health System and Clinic A, there are two paths with a distance value of 2; however, the table displays only one row.

Example 2

Between Health System and Clinic A there are two paths:

  • Health System → Hospital A → Clinic A

  • Health System → Clinic A)

The flat hierarchy table displays only the shortest path (Health System → Clinic A) to prevent duplicate counts when rolling up the data.

View the hierarchy table

The flat_hierarchy table is available in the following sections of the tree view in the SQL Query Editor (Reports):

  • Flattened Hierarchies

  • Customer Master

The table contains the following fields:

Field Name Field Label Field Type Description
entity_vid__v Entity VID VID Veeva ID of the child record.
entity_type__v Entity Type Reference Type of the child record.
ancestor__vid__v Ancestor Veeva ID VID Veeva ID of the ancestor record.
ancestor_type__v Ancestor Entity Type Reference Type of the ancestor record. This value is always HCO.
path_distance Path Distance Number Number of hops from the child to the ancestor. Direct relationships have 1 as the length.
record_state__v Record State Reference State of the path. The value is always Valid. Paths that are not valid do not display in the reporting table.
path_status Path Status Reference Status of the path. The value is always Active. Paths that are inactive do not display in the reporting table.
modified_date Modified Date Date Time The last modified date for any entity or relationship in the path.
path_info Path Info Text Path from the child record to the ancestor using names. The names are separated by the pipe (|) character.
path_info_vid Path Info with Veeva IDs Text Path from the child record to the ancestor HCO using Veeva IDs. The VIDs are separated by the pipe (|) character.

Flattened hierarchy report examples

Review the following examples to see how you can use the flat_hierarchy table.

Example 1 - flat_hierarchy table structure

Use this basic query to view the structure of the table.


select * from flat_hierarchy


Notes about path columns

  • Path Distance - Indicates the level that the entity is from the parent HCO. For example, a value of 1 means that the entity is directly connected to the parent HCO. A value of 2 means that there is another HCO between the entity and the parent HCO.

  • Path Info with Veeva IDs - Displays the Veeva IDs of the entities in the path separated by the pipe (|) character. The entity's ID displays first and then the parent HCO ID displays.

  • Path Info - Displays the names of the entities in the path separated by the pipe (|) character.

Example 2 - Query an entire health system

Report on all of the HCPs and HCOs in a specific health system.


In this example, we are reporting on all of the HCPs and HCOs in the Ascension Health health system.

        ancestor_vid__v = 242979566124008448


Example 3 - Hierarchy levels and counts for a health system

Use this query to report on the levels and counts of HCOs in a health system.


This query joins the flat_hierarchy table to the hco table.

        path_distance AS "Level",
        COUNT (*)
        flat_hierarchy LEFT JOIN hco
            ON entity_vid__v = hco.vid__v
        ancestor_vid__v = 242979566124008448
        "Level" ASC


Example 4 - Health system for HCPs

Use this query to find the health system where HCPs are affiliated.


This query joins the flat_hierarchy table to the hco table.

        LISTAGG (
            DISTINCT corporate_name__v,
            '| '
        ) AS "Health Systems"
        flat_hierarchy JOIN hco
            ON ancestor_vid__v = hco.vid__v
        hco_type__v = '4:37'
        AND entity_type__v = 'HCP'


Example 5 - Rollup counts for HCPs and HCOs

Use this query to display roll up counts for health systems for a specific place and therapeutic area.


In this example, we want to return the rollup counts for health systems in Texas that have HCPs that are MDs and that specialize in oncology.

This query joins the flat_hierarchy table to the hco and hcp tables.

        locality__v || ' ' || administrative_area__v AS "location",
        SUM (
                WHEN hco_ent.major_class_of_trade__v = '32'
                THEN 1
                ELSE 0
        ) AS "Hospital Count",
        SUM (
                WHEN hcp.primary_specialty_group__v = 'G-ON'
                AND medical_degrees IN (
                THEN 1
                ELSE 0
        ) AS "Oncologist Count",
        MAX( path_distance ) AS "Levels"
        flat_hierarchy JOIN hco hco_anc
            ON hco_anc.vid__v = ancestor_vid__v JOIN address
            ON ancestor_vid__v = address.entity_vid__v
        AND address_ordinal__v = 1 LEFT JOIN hcp
            ON hcp.vid__v = flat_hierarchy.entity_vid__v LEFT JOIN hco hco_ent
            ON hco_ent.vid__v = flat_hierarchy.entity_vid__v
        hco_anc.hco_type__v = '4:37'
        AND administrative_area__v = 'US-TX'
        "Oncologist Count" > 5
        AND "Hospital Count" > 1


Example 6 - Skip hierarchy levels

Analytics teams may want to roll up sales and interactions to the closest hospital an HCP is affiliated to and then to the Health System the hospital is affiliated with.

We can leverage the flat hierarchy to skip levels from the HCP to the hospital to the health system.


This query involves a number of joins because we're pulling the names of the HCP, hospital, and health system.

        flat_hospital.entity_vid__v as "HCP VID",
        formatted_name__v as "HCP Name",
        flat_hospital.ancestor_vid__v as "Hospital VID",
        hospital.corporate_name__v as "Hospital",
        flat_hospital.path_distance as "HCP to Hospital Distance",
        flat_healthsys.ancestor_vid__v as "Health System VID",
        healthsystem.corporate_name__v as "Health System",
        flat_healthsys.path_distance as "Hospital to Health System Distance"
        flat_hierarchy flat_hospital JOIN hco hospital
            ON hospital.vid__v = flat_hospital.ancestor_vid__v JOIN hcp
            ON flat_hospital.entity_vid__v = hcp.vid__v LEFT JOIN flat_hierarchy flat_healthsys
            ON flat_healthsys.entity_vid__v = flat_hospital.ancestor_vid__v LEFT JOIN hco healthsystem
            ON healthsystem.vid__v = flat_healthsys.ancestor_vid__v
        flat_hospital.entity_type__v = 'HCP'
        AND hospital.hco_type__v IN (
        and healthsystem.hco_type__v = '4:37'


Example 7 - Find 340B status accounts

Find HCPs and HCOs that rollup to 340B accounts.

If you have a list of Veeva IDs (VIDs), you can use reporting to find the records with the 340B flag.


Upload your list of VIDs as a custom table (Reports > SQL Query Editor).


This query finds any 340B HCO that rolls up to the HCP/HCO record at any level

Change mycustom__ct to the name of your custom table that contains the list of VIDs.

                WHEN entity_type__v = 'HCP'
                THEN formatted_name__v
                ELSE hco_ent.corporate_name__v
        ) AS "Entity_Name",
        hco_anc. "340B_eligible__v",
        path_distance path_info,
        flat_hierarchy JOIN hco hco_anc
            ON hco_anc.vid__v = ancestor_vid__v
        AND hco_anc. "340B_eligible__v" = 'Y' LEFT JOIN hco hco_ent
            ON entity_vid__v = hco_ent.vid__v LEFT JOIN hcp hcp_ent
            ON entity_vid__v = hcp_ent.vid__v
        entity_vid__v IN (
