When submitting an expense report, validate each ticket has an attachment (for example, scanned receipt)

This script validates each receipt has an attachment when submitting an expense report.

Verifies whether document attachments exist on a ticket record
Does not require an attachment if "Missing receipt" is checked

Note:
The Enable the missing paper receipt feature switch needs to be enabled for this option.

Follow the steps below or download the solutions file, see Creating Solutions for details.

Setup

Create a new Envelope form script deployment.
Enter a Filename and click SAVE. The extension ‘.js’ is automatically appended if not supplied.
Click on the script link to launch the Scripting Studio.

Program Listing

          function check_receipt_has_attachments(type) {

    // return if not an approve_request 
    if (type != 'approve_request')
        return;

    // Load receipt data
    var envelope = NSOA.form.getOldRecord();
    var ticket = new NSOA.record.oaTicket();
    ticket.envelopeid = envelope.id;

    var readRequest = {
        type: "Ticket",
        fields: "id, attachmentid, reference_number, missing_receipt",
        method: "equal to",
        objects: [ticket],
        attributes: [{
            name: "limit",
            value: "250"
        }]
    };

    var arrayOfreadResult = NSOA.wsapi.read(readRequest);
    var missingAttachment = [];
    if (!arrayOfreadResult || !arrayOfreadResult[0])
        NSOA.form.error('', "Internal error reading envelope receipts.");

    else if (arrayOfreadResult[0].errors === null && arrayOfreadResult[0].objects)
        arrayOfreadResult[0].objects.forEach(
            function(o) {
                if (o.attachmentid === '0' && o.missing_receipt != '1')
                    missingAttachment.push(o.reference_number);
            }
        );

    if (missingAttachment.length > 0) {
        NSOA.form.error('',
            "The following receipts (by reference number) are missing an attachment: " +
            missingAttachment.join(", "));
    }
