Payroll/Personnel System Overview (PPSO)

Adjustment Processing System (ADJP)

ADJP provides for automatic handling of a variety of payroll adjustments. This system revalidates T&A reports and late personnel actions, performs the debit and credit routine, calculates the difference, and compensates or collects the data accordingly. The automatic adjustment period is 25 prior pay periods plus the current processing pay period for a total of 26 pay periods that can be adjusted.

Form AD-343, Personnel Action Request, may be required for certain adjustments (e.g., back pay with interest, TSP adjustments, etc.). Also a Form AD-343 must be submitted for adjustment to pay for employment with a previous Agency regardless of the adjustment period. PPS will not automatically recompute these adjustments. If the adjustment period exceeds 25 pay periods, whether the employee was underpaid or overpaid by the current or previous Agency, the current Agency must submit a Form AD-343 for processing.
