WebTA Transaction Codes

Transaction Codes (TC), Prefix Codes (PC) and Shift Suffix Codes (SSC) control the rate and kind of pay an employee will receive. They are used to record all time and attendance data, including hours worked, absences, allowances, differentials, and other entitlements. An employee's take-home pay and leave balances are calculated at the National Finance Center (NFC) based on the accurate reporting of these codes in webTA. 

In some cases, a PC or SSC must be recorded with the appropriate TC. PCs are used to record the percentage rate for environmental differential pay and danger pay. They are also used to expand the definition for certain TCs or to create a new TC. SSCs are used to record differential, union representation, and to supplement certain TCs to vary their meanings. 

Descriptor Codes (DCs) are used in conjunction with TCs in the NFC database to allow agencies to track the varying uses of certain TCs. The DCs do not appear on the webTA.

The following Transaction Descriptions are listed in the order they appear in webTA, and where annotated by an “*”, are system generated by webTA. The payable rate, if applicable, is indicated next to the transaction description. Where a PC is annotated with an “XX” the user must enter the appropriate PC.
