Hello Parveen Kumar,
Pallavi mentioned the program, but if you don't have access to t-code se38, try accessing the program through transaction PC00_M99_DLGA20.
On the selection screen, enter your Country Code (if it is not there already), do not enter anything in the WageType boxes, leave the dates as "today", select the edition as a "Table" and execute the program.
In the resulting "report" screen, double clic on the line "Meaning of cumulation wage types", and on the following screen, double clic on Cumulation WT 02 (/102) to see all WTs cumulating into it.
Then, in an other session, access the same program but this time, select the output as "Tree structure", and drill down into the resulting tree until you have the same report.
Note that this program is also very useful to check on which WTs have a certain value for a Processing Class, to look at Evaluation Classes, Average Bases, and Valuation Bases.
