The system doesn't recalculate correctly the quantities open for invoicing when the invoicing period is changed.

this means that the user has to start from scratch to enter the correct invoicing period.

 Technical limitation and  its known issue.

Kindly enter final (desired) invoicing period at once and do not change it later.

 or

If you happen to change or want to change then close it and recrete it with desired invoicing period.

Note:Our developers confirmed that they have added this issue to their backlog and will fix it in one of the future releases.
