Thanks for reply, Vinod. But I checked the FM DATE_CHECK_PLAUSIBILITY in my system with value '20032013', it worked but when I tried the value '20130320', it had wrong format.
Additional, can you guide me how to find the error record that has invalid format date; because when I input the invalid value on Selection Screen of PSA Table, system display message"Invalid date":
Thanks you,
