PT40 doubt

Hi masters,

I have a doubt about PT40.

Myevaluation periodis from 16th of previous month to15th of current month.

I throw time evaluation, and some employees have time events lost, for example. I go to PT40, and fix these time events, and employee for employee, i throw PT60 with the button that I mark in red

In this case, i´m evaluating from 2nd January from 15th January. When I fix the time event from 14th, and rerun time evaluation from the button I mark in red, the evaluation is calculate from actual day, 28.10.2014, and then, in infotype 0003, retroactive CDP is fill with actual day.

My question is, from PT40 I can rerun evaluation to 15th of January, or it´s forced to rerun to actual day?

Any ideas?
