Transaction tables store data about day-to-day business activities. Transaction tables are normally keyed in by Business Unit.

Control tables store information that define the accounting structure and processing rules that are used when transactions are entered into your PeopleSoft applications. Control tables include master lists such as customers, vendors, products, country and location tables. It is important to note that Control tables are static, meaning they only change when you perform specific maintenance on them. Transaction tables on the other hand change frequently as they are in constant use to perform the day to day transactions in your company. Most control tables are keyed by Table Set Identifier, rather than by Business Unit (transaction tables).

Thanks for your quick reply

Eg:
One of the important Transaction table in HRMS is PS_JOB and PS_DEPT_TBL, PS_COMPANY_TBL, PS_LOCATION_TBL etc are some of the control tables.

Most of the times Control Table names ends with _TBL.

Thanks,
