please explain your requirement
@RABINDERSHARMA Do you want to have a comment line item for each row (exp1, exp 2)? I'm still not clear on your ask.
Yes I want comment line for each column or reason explaining the variance.
@RABINDERSHARMA I feel I'm still missing something.If this is the case, and you are looking for a one-to-one relationship, then adding a line item in the module dimensioned by Exp1, Exp2,..... should achieve that.If you want MULTIPLE comments for one item of the list, then you have to create a child list to achieve this one-to-many relationship.
