I don't know the answer, but.... In Payroll Setup, have you opened earnings code maintenance and put your double time earning code next to say regular time to see if there is some setting different that would cause this?  I would start there.

Then, if you don't see anything, open deduction code maintenance for 4P, and hit the Earnings button to see if it has all earnings types, and exclusions are not funky.

Is the earnings code for double time imported after the 4P deduction?  If so, try placing it above the deductions.

You're either missing some required fields in your import job or your records tab is not defined properly or missing the perform logic needed.

Refer to the following KB's:

KB21326 - How to import into payroll data entry using Visual Integrator

KB52022 - Automatic Deductions are missing when importing in PR.DATAENT

If you still can't figure it out and have a support plan, you can e-mail your import job to [email protected] and Sage support can examine your import job.
