Well if the decision was in my hands, I would have done that but I am not allowed to. So I have no option but to make this hierachy system and then a plugin which creates and displays reports based on this system.
And that is turning out be real difficult for now coz I have my hierarchy created but creating a multiselect list having all depts/sects/areas and mapping each user to the hierarchies they have access to is turning out to be a very tricky task.
Working on that curently, but once thanks to u n @Ben for taking out time and interest and replying to me continuously.
You might see more of me on this forum for different questions can be silly n obvious or difficult and sensible.
