SPO Dynamic Partition by using BAdi

Hi Experts,

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

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

at first run; partiton1 should have 2013, partiton2 :2014 and partition3 : 2015 data.

at second run; Partition1 should have 2016   and

at third run; partition2 should have 2017 data..

i think on the GET_T_PART_CRIT method corresponding code has to be written.

can anyone help me with the code ?

thanks in advance.

Erdem.
