You can keep All Dataset parameter as it is and create a new parameter for required dataset.

Hi Sajith 

Thanks for details. but my question if keep All Dataset parameter as it is and create a new parameter for required dataset. how to PSO segregate like 40 Dataset using 14 days window screen and only one dataset want 24 days if keep all dataset then also consider segregate data set also like below only one dataset want 24 days and 24 day schuduling 

PSO is not doing anything here. FSM alters the values inside Input_Reference entity attribute in Load file of each dataset. Eg: Assume All Datasets parameter value is 14 days and only for dataset ‘X’, you have defined a separate parameter with 7 days.

Then for “X” dataset, scheduling window will be 7 days and for the rest it will be 14 days.
