Have you run live time eval?
Run time eval with log for a pay period; display log for CUMBT or add a line in the schema to print ZL & DZL for each day (e.g/., PRINT NP ZL) before EDAY function in time eval schema and then run time eval with log.
Check if there are any ZL or DZL entries created.
If not, there is a problem with one or both of
a)time schema PCR's where you may have ADDZL to add to ZL with
IFTYP A, M, or S
b)V_T510S config, if you are using GWT to generate time w/t's and the PCR's which create the proc type in TIP with op'n FILLP option V (i.e., FILLPV)
