You can achieve this by using a Catalog Client Script. Here are the steps:
1. Navigate to Service Catalog > Catalog Definitions > Maintain Items.
2. Open the catalog item you want to modify.
3. Under the related links, click on "Client Scripts".
4. Click on "New" to create a new client script.
5. Fill in the fields:
- Name: Give a meaningful name to your script.
- Type: Select "OnLoad".
- Catalog Item: Select the catalog item you are modifying.
6. In the "Script" field, write the following JavaScript code:
javascript
function onLoad() {
//Get the values of the two variables
var input1 = g_form.getValue('input1');
var input2 = g_form.getValue('input2');
//Concatenate the values with a space in between
var description1 = input1 + " " + input2;
//Set the value of the detail description field
g_form.setValue('description1', description1);
}
7. Click on "Submit" to save the client script.
This script will run every time the catalog item is loaded, and it will populate the 'description1' field with the values of 'input1' and 'input2' variables.
Please replace 'input1', 'input2', and 'description1' with the actual names of your variables and field.
