Issue with Invoicing Partial Timesheet Details

[SamuelHelbling]

Information about bug

When invoicing a single timesheet detail for one project, the entire timesheet is marked as billed, preventing further invoicing of other projects in the same timesheet.

Steps to reproduce the bug:

1. Create a timesheet with multiple timesheet details for different projects.
   For example:

   • Timesheet Detail 1: 10 hours for Project 1, marked as billable.
   • Timesheet Detail 2: Hours for Project 2, also marked as billable.
     

2. Submit the timesheet.

3. Create a sales invoice for one of the projects (e.g., Project 1) and use "Fetch Timesheets" to get billable hours from timesheets. You get 10 hours.
   

4. After submitting the sales invoice, observe that all the hours in the timesheet are marked as billed, rather than just the hours for the invoiced project.

5. Attempt to create a sales invoice for the second project (e.g., Project 2). Notice that the remaining 10 hours no longer appear as available to invoice, even though they haven’t been invoiced yet.

Expected Behavior:
Only the hours associated with the invoiced project (e.g., Project 1) should be marked as billed, leaving the hours for other projects available for invoicing.

Actual Behavior:
The entire timesheet is marked as billed after invoicing one project, preventing further invoicing of other projects' hours.

This bug can become a serious problem for companies.
