If you have a different client address in the timesheets although they belong to the same purchase order, the system breaks the invoices up by purchase order number, and then client invoice address.
You need to credit and re-invoice with the correct invoice address for the timesheets. You can do this by following the below instructions.
Also, to avoid this in future you must check the invoice addresses on each timesheet before invoicing:
Click Invoicing then select Credit and Reinvoice.
Select the client ref then enter the credit code of MISC.
Click Start then click Invoicing.
Generate the Credit notes then enter the client ref in from and to the client.
Click Start then click into the Timesheet search.
Find the timesheets that need the invoice address correcting.
In Maintain, select the timesheet.
Make the required change then click Invoicing.
Tag the Timesheets for invoicing then enter the client ref.
Select the desired timesheets using the toggle button.
Select Tag timesheets for invoicing.
Click Invoicing then click Generate Invoices.
Enter the client ref in the To and From Client.
Select Process Tagged timesheets only then click Start.
