pls help me understanding following calculation rule
as per calculation rule MODT
I know that PAYTP is a operation and A is indicating to take employee subgroup grouping from CAP.
i also know W is referring table T510S and T is referring table T555Z and A is referring table T554C and L is referring T559P.
As per the above example each alphabet (W, T, A, L) is indicating a value "=01" from the respective table, i don't understand which value in the table it refers. I need your help to understand it.
Thank you for your time and answer
