I have a datatable which has lot of columns and rows out of which I need to group the data based on a column and take decision to trigger notification based on another column.
Below is a small example where in we need to group the data based on layers and if two adjacent layer have same attachment point we need to trigger a notification
Layer Attachment Point
1 100
1 200
2 200
3 200
My requirement is if two adjacent layers suppose layer 2 nd 3 both have the same value in attachment point column then I need to trigger exception, and there are other columns as well in this datatable
