I would appreciate some help on this, I am currently working on a item, the SAP CL Invoice Number is coming from CRM for example CL00131713, on my HTML view it is getting correctly mapped, however the requirement states there should be a - in the SAP CL Invoice Number. This should show as CL-00131713 like the image below: 

[![enter image description here](https://i.stack.imgur.com/tJLbj.png)](https://i.stack.imgur.com/tJLbj.png)

My code is in my model.cs 

```
public string SAPCLInvoiceNumber { get; set; }

```

In my organisation.cs class 

```
result.Add(new InvoiceModel
{
SAPCLInvoiceNumber = invoice.SAPCLInvoiceNumber,
});.

```

Finally in my HTML I do

```
<tr ng-repeat="invoice in vm.invoices">
<td>
<!-- {{invoice.Number}} -->
{{invoice.SAPCLInvoiceNumber}}
</td>

```

I believe I need to do something like 

```
SAPCLInvoiceNumber =   string.replace("CL","CL - " + string.replace("CL", SAPCLInvoiceNumber )) 

```

Please advise
