My current working model is like this:
Hundreds of CSV files placed in one directory, they are read by QVW and one QVD is created from them, another QVW laods data from QVD and shows results on front-end (dashboard).
Now, the requirement is, user can select some check boxes (reatiler, category, date ect.) from the dashboardand based on those selections, I need to find such rows in CSV files and prevent them from loading again.
Some kind of a flag can be put in those rows or embed some unique caharcters in ID field that would stop them from loading in furtue. The goal is to not load those rows but to keep them in CSV files.
