Max Sequence to have Previous Sequence String Value

Wed, 19 Oct 2016 19:02:42 GMT

Hi All,

I have this request to find out the latest User Name before the "CRR" Activity Code and then have a new field containing that name for the Maximum sequence of "CRR" code available for a ID.

Check this below table, I need "New Field Required" column.

For Instance: ID = In 246014, the latest CRR sequence = 3, but I need the name of previous (non CRR code) user name in the new field.

NOTE: I need everything to be done at script level.

ID	Seq Number	Activity Code	Completed By	New Field Required
242653	6	CR
242653	5	CRR	Martinez, Jacqueline	Myszka, Brooke
242653	4	CRR
242653	3	CRR
242653	2	CRR
242653	1	RA	Myszka, Brooke
246014	4	CR
246014	3	CRR	Osborne, Jodi	Thorne, Shawn
246014	2	BA	Thorne, Shawn
246014	1	BA

Thanks,

Angad

You could do this within a sorted load per Peek() or Previous() ?
