SPO Dynamic Partition using by BAdi

Hi Experts ,

i want to create badi for my IC SPO which has 3 partitions.

when i run t-code RSLPO_MASS_ACT, it should fulfill the partitions as below:

at first run ; partition1 should have 2013, partition2 : 2014 and Partition3:2015 data.

at second run; partition1 should have 2016  ,

at third run ,Partition2 should have 2017 data.

i guess on the GET_T_PART_CRIT method correnponding code has to be written.

can anyone help me on that code ?

thanks in advance.

Erdem.
