Comment 4 for bug 948876

Hello Erwin and Martin Hermann,

As the task work creates Analytic Line which allows you to creates invoice from Analytic Line.
Now when you are validating the created invoice it will create another costing entry from invoice line by taking analytic account.
So there is no mean to create invoice from this analytic line.The system only restrict when the invoice is linked with a particular analytic line.
This case is a special case where analytic line does not contain invoice link.So the system will always allow you to create invoice.
This entry is considering in a costing entry part so as per my opinion this issue may not consider in a bugs this is wrong configuration issue.

I think this requires more discussion on different experts side.

@experts: Would you please share your opinion on this.
