Processing Data with a DQM Event

When the Start DQM Event process finishes, the DQM Event Review Form opens and displays results in a series of tabs:

 

Event Summary

Review Exceptions by Check

Review All Results

Review Samples and Results by Sample

Errors

 

The Event Summary tab displays a summary of the DQM event, the number of results evaluated, and the number of exceptions to the checks. Qualifiers and remarks can be revised on the Review Exceptions by Check, Review All Results, and Review Results by Sample tabs.

 

Note: If errors are encountered during the creation of an Event, the Errors tab is displayed first.

 

During the Start Event step, DQM adds several new columns to the Analytical Results output table, including DQM_QUALIFIERS, DQM_REMARK, APPLY_QUALIFIER and APPLY_REMARK. When DQM discovers an exception to a DQM Rule, both QUALIFIER columns are populated with that rule's qualifier. The DQM_QUALIFIERS and DQM_REMARK columns cannot be edited (to preserve a record of the DQM suggested qualifier).

 

Once the DQM Event is started, data validators can review the DQM generated flags by check, sample, or other user-applied filter. The APPLY_QUALIFIER column and the APPLY_REMARK column can be edited on the DQM Event Review Form, once the event has been saved. Any in-process events can be saved for future reference and can be edited at a later time. These changes are stored in a variety of DQM tables in the EQuIS Database but changes to other data tables do not occur until the DQM Event is complete. When the DQM Event is Complete, the APPLY_QUALIFIER column is saved to the VALIDATOR_QUALIFIER and/or INTERPRETED_QUALIFIER columns in DT_RESULT according to the options selected.

 

There are two remark fields that are shown in the various screens in a DQM event and that are saved to the database upon completing a DQM event.

1.Apply Remark
The Apply Remark appears in the Apply Remark column when you are in the DQM Event screen. The initial remark that is displayed in the Apply Remark column is defined in RT_DQM_RULE.REMARK for a DQM QAPP, Check, and Rule; this remark field can be configured by the user to display the exact text desired for each DQM rule.  Users may revise the Apply Remark on a specific data set that is initially displayed in the DQM Event screen as appropriate. Once a DQM event is completed, the Apply Remark is saved to the DQM_REMARK field of the DT_RESULT table.

2.Remark
This REMARK or DQM_REMARK column is accessible via scrolling to the right. The data displayed in this field are autogenerated by DQM based upon inputs from the specific configuration of the DQM QAPP selected for the DQM Event and upon the rule that has been exceeded; this remark is not configurable by the DQM user.  Once a DQM event is completed, the Remark is saved to the REMARK field of the DT_RESULT_DQM table.

 

Note: A DQM Event must be Saved before it can be Processed and/or Completed. After upgrading EQuIS Professional, ensure the current installed DQM report assembly (EarthSoft.Reports.Library.63867.dll) is published to the EQuIS database (Publish a Report - Quick-start Guide).

 

 

Processing the Event

 

Event Summary Tab

 

Review the Event Summary tab to determine if DQM found any exceptions to the DQM checks applied to the data set. The Event Summary tab displays a summary of the DQM event, the number of results evaluated, the number of exceptions and a row for each check that was run with the following columns:

 

1.Check Name – In addition to the names of the listed checks, this column also includes the row header for some additional information such as the DQM QAPP Code, Holding Time Types, MAG Code, Unvalidated Only Option, and Field Quality Comment option.

2.Type of Sample or Result Reviewed (by the Check) – For the checks, this column lists the values from the DQM Settings used to select results for review by that check.

a.For example, the Relative Percent Difference Field Check looks for "S = FD" (i.e., DT_SAMPLE.SAMPLE_TYPE_CODE = 'FD') as specified by the sample_type_Field_Dup check parameter.

b.Another example is the Surrogate Recovery Check that looks for "R = SUR" (i.e., DT_RESULT.RESULT_TYPE_CODE = 'SUR') as specified by the result_type_code_surrogate check parameter.

c.For the other types of rows (DQM QAPP Code, etc. listed above) this column displays the value of that particular row header.

d.If there were errors when the event was started, the number of errors is listed.
 

3.Total Number of Results – The total number of results retrieved to start the event dataset.

a.The dataset will always include all of the results from the selected group (e.g., DT_SAMPLE.TASK_CODE = 'XYZ') with DT_RESULT.RESULT_TYPE_CODE = DQM.GLOBAL_PARAMETERS.RESULT_TYPE_CODE (defaults to 'TRG') and DT_RESULT.REPORTABLE_RESULT = DQM.GLOBAL_PARAMETERS.REPORTABLE_RESULT (defaults to 'Yes, Y').

b.Including some checks in the event will add to the total number of results in the Event dataset. For example, including the Surrogate Recovery Check will also include results with RESULT_TYPE_CODE = DQM.SURROGATE_RECOVERY.RESULT_TYPE_CODE_SURROGATE (defaults to 'SUR').
 

4.Number of Results Reviewed (by the Check) – The number of results in the Event dataset that were processed by this check.

a.When the Type of Result Reviewed column is All Results, this will be the same number as the Total Number of Results.

b.When the check lists a specific type of sample or result to be reviewed, then this will be the number of results with that type of sample or result.
 

5.Number of Exceptions – The number of results that failed the check criteria (e.g., a result from a trip blank sample with a detected concentration).
 

6.Method used to Find Associated Results – When Exceptions are found, DQM then looks for associated results using the method listed here (e.g. a matching Test ID, Test Batch ID, or SDG). The method used to find associated results is different from check to check.
 

7.Number of Results Associated – The number of regular results that were qualified due to their association with the Exception result using the method listed.
 

DQM.Event.Summary

 

Errors Tab

 

Any non-fatal errors that were encountered during the Start Event process will be displayed In the Errors tab. When errors are encountered during the creation of an event, the Errors tab is displayed first. If errors are denoted on the Errors tab, resolve the errors before proceeding to the next steps. Once the needed changes are made to resolve the errors, the DQM event will need to be restarted.

 

If errors are listed, the suggested workflow is:

 

1.Close the event without saving.

2.Repair problems with dataset identified in the errors.

3.Restart the event.

 

If an Event is saved regardless of errors, the particular error messages are not saved.

General Notes about Review Tabs (by Check, Review All Results and by Review Samples)

 

When changing any of the Apply Qualifiers and/or Apply Qualifier Remarks, Save is required before leaving that tab (or lose the changes).
 

Changed values in the Apply Qualifier column are saved in the DT_RESULTS_DQM table when the event is Saved, but they are not "applied" to the qualifier column in DT_RESULT until the event is completed.
 

Only values with STATUS_FLAG = 'A' in RT_QUALIFIER can be entered in the Apply Qualifier column by any of the methods below. The Apply Qualifier can be updated by:

oEntering a value in the yellow-background text box under the Update Q button and clicking the Update Q button, or

oEntering a new value directly into the Apply Qualifier column of a single result by selecting a value from the RT_QUALIFIER drop-down list in that column.
 

The values in the Lab, Validator, and/or Interpreted Qualifier columns and/or the existing value in the Apply Qualifier column itself can be included in the Updated Apply Qualifier column by checking the check box over the Qualifier columns to include any values in those columns when the Update button is clicked.

oIf a letter is included in two or more of the Included qualifier columns, it will only be included once in the Apply Qualifier.

oIf the yellow entry field is NULL, the values in any checked qualifier columns will still be included in the Apply Qualifier column.
 

If the Apply Q check box is left unchecked, clicking the Update Apply Q button overwrites the existing values with whatever is in the yellow entry field. This includes clearing any values if the yellow entry field is NULL.
 

The Apply RC column (RC = Reason Code) can be updated by:

oEntering a value in the yellow-background text box under the Update Apply RC button and clicking the Update Apply RC button (this will only update the Apply Reason Code in rows with the Apply Qualifier column populated), or

oEntering a new value in the Apply Reason Code column of an individual result.

oThe value placed in Apply RC, should equal a REASON_CODE in RT_DQM_REASON.

 

Clicking the Filter button in any column header will open the filter selection window for that column.

 

When the set_NQ_to_NULL Global Parameter = FALSE:

oIf DQM Q column = 'NQ', then Apply Q column = ‘NQ’;

oDuring the Process Event step, filter DQM Q column for ‘NQ’ and

oManually batch update the Apply Q column to NULL during the review process.
 

When the set_NQ_to_NULL Global Parameter = TRUE:

oIf DQM Q column = 'NQ', then Apply Q column = NULL;

oThe results will still show up in the Exceptions tab of the DQM Process Event screen.

 

Review Exceptions by Check Tab

 

The Review Exceptions by Check tab shows the results which failed the selected checks during that Qualification run (Exceptions) and the results associated with those Exceptions (Associated Results). Analytical Result rows may be listed more than once if more than one check and/or rule was violated, but they are separated by check unless the "ALL CHECKS" selection is chosen from the DQM drop-down box.

                                                                       

If there are exceptions, select the Review Exceptions by Check tab. For each DQM check with an exception, review and change the suggested qualifiers as needed. Elements of the Review Exceptions by Check tab are:

 

1.The different Exceptions are displayed by selecting a DQM Check in the drop-down box.

2.The Associated Results for that check are displayed below the exceptions.

3.The visible results can be filtered and/or sorted by clicking the Filter button on any column header.

4.The visible fields for the Exceptions and Associated Results for the Exceptions by Check can be modified by selecting the filter button and selecting or deselecting the listing of available fields for “Exceptions by Check” and “Associated Results”. The fields to the left of the field/column “sample” in the following image will always be visible and cannot be deselected. If you would like to save your selections, select to save your selections under the “Load/Save Configuration” tab. To enable the saved configuration when running another DQM Event, return to the filter button and select to load your configuration using the “Load/Save Configuration” tab.

5.The is a green arrow located above the right-hand column of additional fields; if the green arrow is selected, the right-hand column of additional fields will be minimized to provide additional room to display the fields for Exceptions and Associated Results. To maximize the right-hand column of additional fields, simply select the green arrow again.

6.The Apply Qualifier can be updated by using the Include check boxes and the Update Q button.*

7.The Apply Reason Code can be updated by using the Update Apply RC button.*

8.The Apply Remark can be updated by using the Update Apply Remark button.*

9.When an Exception record or an Associated Result record is selected, the associated data from the Analytical Results Report are displayed in the vertical list on the right.

10.The warnings for the selected check are displayed below the associated results or below the exceptions if there are no associated results for the selected check.
