Question { IBM, 25740 }

What is MDT? What are FSET, FRSET ?

Answer

Suppose you display a map and consider the function of that map is to update.To update ,first u fetch a particular record with some id(primary key) . Suppose there are 3 field name ,mark 1, mark2 and you
Just updating mark1 alone.Then
Mdt for name = 0
Mark1 = 1
Mark2 = 0
, So that only mark1 get updated . Name and mark2 will be null.
In order to avoid that we go for fset
Fset will set mdt value for all feild as 1
So ur update will processed perfectly.So, ur name and mark2 will be same as pervious value.
Frset is used to set mdset = 0 for all feild.
