A0123 A0123A *FILE CLM/D07 D07 1
A0123 A0123A *FILE CLM/D08 D08 2
A0123 A0123A *FILE CLM/D05 D05 1
A0123 A0123A *FILE CLM/D05 D05 2

Whenever i do Chain its picking 3rd record that is fine by definition of chain, please help me to build logic to update 4th record when user selects option '2' against 4th record and to update 3rd record when user selects '2' against 3rd record. Please help..
