An evaluation of several assignment levels of a contract, in this case 4 sub-projects, would be desirable, which compares the trades and LpH with the order amount with the amounts already settled.

Evaluation should be possible by assigning performance tags. If you then filter the values “Invoices (service period and invoice date) via the “Office | Evaluations | Projects by Period” area, this can be compared with the order values.

I have stored the performance tags, but only one performance tag per dimension can be evaluated, as was explained to me. That makes implementation rather difficult.
