I am using TM04 schema in time management. As per the definition of -ve TM, we can only record deviations. these deviations may be absences, substitutes, overtime and leave quota carry forward.
But in my opinion TM04 is only useful to record absences, because we can maintain OT hrs and substitution in IT2010 and quota carry forward may be maintained in table V_T559L thru "validity/deduction interval" by mentioning all 9s in relative position.
I am seeking more input if any as far as TM04 functionality is concerned.
