Client Side SuiteScript to Calculate Mileage on an Expense Report

To calculate Mileage on an Expense Report (Navigation Path: Transactions > Employees > Enter Expense Report).

Follow the steps to create custom fields and Script to calculate Expense Report:

1. Create Transaction Line custom Field "Distance".
a. Navigate to Setup > Customization > Transaction Line Fields.
b. Label = Distance (Note : user can change this to desired label)
c. ID = _distance (Note: Auto-generated by system, but can be changed to user's preference. If changed, please make sure to do the necessary changes in the code.)
d. Type = Decimal
e. Store Value = Checked
f. In the "Applies To" Subtab, check "Expense" and "Expense Report".
g. In the "Display" subtab, Display Type = Normal.
h. Click Save.

2. Create another Transaction Line custom Field "Rate".
a. Navigate to Setup > Customization > Transaction Line Fields.
b. Label = Rate (Note: user can change this to desired label)
c. ID = _rate (Note: Auto-generated by system, but can be changed to user's preference. If changed, please make sure to do the necessary changes in the code.)
d. Type = Decimal
e. Store Value = Checked
f. In the "Applies To" Subtab, check "Expense" and "Expense Report".
g. In the "Display" subtab, Display Type = Normal.
h. Click Save.

3. Write the JavaScript code for calculating Mileage
(Note: This scripts work only for "Travel" keyword in the "Category")

a. Create a JavaScript file "Calculate_Mileage.js".
b. Copy - paste the code below:

function xCalcMilage() { var milestraveled = nlapiGetCurrentLineItemValue('expense', 'custcol_distance'); var rate = nlapiGetCurrentLineItemValue('expense', 'custcol_rate'); if (milestraveled == null || milestraveled == 0 || milestraveled == "") { return false; } var xTotal = milestraveled * rate; // calculation nlapiSetCurrentLineItemValue('expense', 'amount', xTotal); // sets amount alert('expense amount: '+xTotal); return true;}function xExpenseReport(type, fldname) { alert('enter xExpenseReport'); var CategoryValue = nlapiGetCurrentLineItemText('expense', 'category'); var travel = CategoryValue.match(/travel/gi); if (travel != null) { xCalcMilage(); } return true;}
4. Create a Client Side Script to "Calculate Mileage".
a. Navigate to Setup > Customization > Scripts > New. Select Type as "Client".
b. Name = Calculate_Mileage (Note: user can change this to desired label )
c. ID = _calculate_mileage
d. Under the "Scripts" subtab, Script File = Calculate_Mileage.js (Note: Add the JavaScript file created in Step - 3) and Validate Line Function = xExpenseReport.
e. Under the "Deployments" subtab, set Applies To = Expense Report, ID = _calculate_mileage, Deployed = Yes, Status = Testing/Released.
f. Click Save.

Now once user creates an Expense Report and selects "Travel" in category, and insert Distance and Rate in the respective line fields, clicking the "Add" button will compute the "Mileage" and assign it to "Amount" field.
