Expense Report - Custom Save / Submit Validations (Stored Procedure)

Customer specific logic can be defined in a database stored procedure to perform custom validations upon expense report entries.  These validations can be configured to run at the time an expense report is saved (ie retrieved for display) or upon submittal.   Customers can have their own IT personnel create the stored procedures or work with Unanet's Professional Services team to have custom procedures created for them.  For On Premise customers, the loading and setting of necessary permissions for the stored procedures are the responsibility of your local site administrator and DBA.

To enable the stored procedure feature, your Administrator will need to supply the name of the custom stored procedure in one or both of the following properties: Save Stored Procedure (unasense.save.stored_procedure) and/or  Submit Stored Procedure (unasense.submit.stored_procedure).  

Note: This feature will not apply to expense requests (that is, these additional validations will only occur for expense reports).

 

When an expense user clicks on the Save or Submit button, the Unanet system will first perform the standard built-in validations.  If all standard validations pass successfully, the expense report data will be saved to the database.  At this point, the stored procedure will be called and the additional custom validations will be considered.  In this way, regardless of the success or failure of the stored procedure logic, the user's changes will be saved.

Stored procedure validations can be configured to validate for both Error or Warning conditions.   When running a 'save' stored procedure, there is no real difference between error and warning conditions, as any errors or warnings will be presented on the screen along with any built-in validation error messages (these will appear in red text above the expense report).  When running a 'submit' stored procedure, however, users encountering an Error condition are only presented with an option to re-edit the expense report (the submittal is prevented), where as in the case of a Warning condition, the user can optionally re-edit the expense report or chose to continue with the expense submittal.

Expense Import Note: When enabled, the stored procedure is only invoked when a user is using the web interface expense report screen.  That is, the stored procedure is not invoked for expense reports "submitted" via the expense import mechanism.  

 

If your site is using a stored procedure prepared by the Unanet Technical Services Group, note that they often earmark the Person UDF #5 for the purposes of controlling stored procedure Test Mode indication.

 

This page covers the following topics:


Syntax

<stored_procedure_name> (expense_report_key IN  number(15,0),
                         submitter_key      IN  number(15,0),       (use optional submitter_key with submit validations and saver_key with save validations)
                         return_code        OUT number(15,0),
                         error_message      OUT varchar(2000))

 

Note:  Passing of the submitter_key parameter is only enabled when the Include Submitter when calling Submit Stored Procedure (unasense.submit.stored_procedure.include_submitter) property is enabled.  Likewise, passing of the saver_key parameter is only enabled when the Include Saver when calling Save Stored Procedure (unasense.save.stored_procedure.include_saver) property is enabled.

The following rules must be followed when using this feature:

Stored Procedure Name

The name of the store procedure is defined by the customer.  This name must match the value that is set with the Submit Stored Procedure (unasense.submit.stored_procedure) property or Save Stored Procedure (unasense.save.stored_procedure) property.  

For example: unasense.submit.stored_procedure=sp_expense_submit_validation.

Note: Be careful to not use the same name that you may have used for the timesheet stored procedure if you have one already installed.

Input Parameters

 

  • Person Expense Key

Identifies the specific expense report being saved or submitted.

This is a required input parameter.

  • Submitter Key, or

  • Saver Key

Identifies the key of the user saving or submitting the expense report.

This is a optional input parameter.

Note:  You should only pass this optional parameter if the stored procedure logic requires the additional input data.  When passing this optional parameter, you must also enable the corresponding   Include Submitter when calling Submit Stored Procedure (unasense.submit.stored_procedure.include_submitter) or  Include Saver when calling Save Stored Procedure (unasense.save.stored_procedure.include_saver) property (as this property instructs the stored procedure call to expect the additional parameter).  

Requiring the additional parameter and not providing it -- or -- providing the additional parameter while not setting the property to expect it will both result in a sql exception at runtime.

  • Return Code

The first output parameter is expected to be the return code from the stored procedure.  

  • A value of 0 (zero) will indicate success
  • A positive value will indicate an Error condition
  • A negative value will indicate a Warning condition.  

 

When using the 'submit' validation (vs. the 'save' validation); in the case that a zero (0) (success) is returned, the Unanet submit logic will continue.  In the case of a non-zero return code (Error or Warning), the contents of the second output parameter (Error Message) will be displayed to the screen and the submit logic will not continue.  In the case of the Warning message, the user is subsequently presented with an option to either re-edit the expense report, or to proceed with the submittal.

  • Error Message

The second output parameter is expected to contain a message to accompany the non-zero return code, presumably to explain the reason for failure.  If a non-zero return code is returned, but no value is supplied in the message parameter, Unanet will supply a default message indicating no custom message provided.  

 


Configure the Stored Procedure

In order to configure the stored procedure in your system, you will need to take the following steps:

  

Important -- Please be sure to grant the necessary permissions to the unanet database user.  If the database user name is not 'unanet', you must replace the 'unanet' string in the script with your database user name.  If the permissions are not granted to the appropriate database user name, your users will get a SQL Exception when the stored procedure is invoked.


Examples

The following section includes an oracle and sql server version of a stored procedure that include both a Warning and an Error example.
