Consider the below configuration with an empty position.

Seq #       Position #     Reference Part #

1                POS1             Blade 1

-                 POS2             Blade 2

3                POS3             Blade 3

4                POS4             Blade 4

On clicking ‘Re-Number’, the sequence number is generated for empty position as shown below:

Seq #       Position #     Reference Part #

1                POS1             Blade 1

5                POS2             Blade 2

3                POS3             Blade 3

4                POS4             Blade 4

On save, the sequence number is generated in multiples of five.

Seq #       Position #      Reference Part #

5                POS1             Blade 1

25              POS2            Blade 2

15              POS3            Blade 3

20              POS4            Blade 4

On further save, records are rearranged in the ascending order of Seq #, as shown below:

Seq #       Position #      Reference Part #

5                POS1             Blade 1

15              POS3            Blade 3

20              POS4            Blade 4

25              POS2            Blade 2
