If a parent is querying a meals balance from a previous academic year you are able to see the meals taken and payments made historically.
To view this go to Admin > Meals > Student Meal Payments - select the year the student is in now and choose.
Find the student required and click onto View on the far right hand side of the screen under the statement header.
In this area if the student had meals assigned previously within ScholarPack you should be able to select to view these years by clicking onto the year required underneath previous years.
