    Hi Raj

    The LRT is a table for payroll processing. It is such an important one if you want to get the Last Result Table (run before already) and now you want to use in current period.

    You can refer the scenario why you need to use LRT

    With standard payroll schema, you can refer Singapore payroll as they have a legal requirement is that any difference should be carried to current month. Therefore they use LRT as well.

    E.g in Jun, you run payroll with Basic pay = 4K.

    => CPF (you can considered as social insurance) = 4K x 20% = 800.

    In Jul, update backdated basic pay from 4K to 4.5K. We definitely have 2 periods:

    1. for Jun in Jul

    => but CPF for Jun in Jul must be the same: 4K x 20% = 800.

    ==> Therefore SAP use LRT to compare that for Jun in Jun: 4K, for Jun in Jul: 4.5K

    ==> 500$ will be carried to for Jul in Jul.

    ==> Then CPF for Jun in Jul is still 4K x 20% = 800.

    2. for Jul in Jul

    ==> CPF will equal 4.5K (in current period) + 500 (difference in retro) = 5K x 20% = 1000.

    Hope you are clear why we need LRT with 2 above real scenarios. If you want to have more document about schema, you might look at my blog Useful documents for Schema & PCR configuration
