Choosing field requirements and validation types
For each user-defined column that you select to appear on time cards, your choices for field requirements are:
| Required | The employee cannot save the time card unless a value defaults or the employee makes a manual entry. Typically associated with a hard error message. | 
| Optional | The employee can save the time card, even if the field is blank. Typically associated with a soft error message. | 
Your choices for validation types are:
| Hard Error | The employee must change the entry before s/he can save or submit the time card. | 
| Soft Error | The employee does not have to change the entry in order to save or submit the time card, but e-timecard places a notation on any line with a soft error. | 
| None | The program does no error checking. |
