Expenses by projects issue

We are facing an issue with expense claims, the current setup doesn’t support multiple projects in one expense claim, most of employees apply their expanses in the last week of the month and they do it in one expense claim request, the issue is, most of the employees work on different projects through out the month so we end up with multiple projects in the same expense claim, I tried to add a field in the expense claim details DocType called project and linked it to projects, it shows up and works fine but yet it doesn’t reflect on the project expanses even after the payment is done.

the only thing works and reflect on the project expanses is the project field under the accounting dimension in the expense claim form.

any thoughts on this would be appreciated.

Just adding the link won’t do anything. You also have to back it up with the code changes.
