I have a program with an Array of 5000 occurences which is being passed from 5 sub levels to the front end screen. Thess 5 programs using each 5*2 = 10 different arrays with size as 5000. This is causing the transaction to utilize more storage consupmtion. I am looking to reduce the storage consumption. As part of that initially i thought Dynamic array may solve my problem. After viewing the comments given i see its same as normal array. IS there any other way we can resolve this issue?
