HI Sravani ,
Please gothrough my comments on this .
/616 is only calculated in cases of cross FY retro cases. It is basically determined taking the differnce of gross total income (/416) in original run for 12 period of previous FY and results existing for 12th period in the current FY when retro is triggered. Now, /416 will hold the same value at both the places, so the difference is taken by:
(a) (/410 + /411 +/413 - /414) calculated in original 12 in 12.
(b) (/410 + /411 +/413 - /414) in retro run for the 12th period in current FY.
The differnce of b-a should be equal to /616 dispalyed currently. However incase you would like /616 amount not be generated, it has to be adjusted using M89G wagetype and provide the equivalent negative amount of /616 throught IT0015 . you need to copy a wage type from M89G - to 989G and update the amount of each employee in 15 infotype with reverse symbol . Ex: IF u got one employee /616 as 5000 and u need to give that in 0015 infotype as -5000 in the wage types 989G. Through this you can nullfy the amount .
