Hi Experts,

Right now we have three data load rule for pulling the data from ERP to EPM Application. one for Net Income ,another for Balance sheet and additionally we have created one more for Net utility plant things related data(part of Balance sheet). and right now the script execute based on one data load rule which means once the first data load completed then next will start running. All these are happening in sequentially which is time consuming.
