How do I count vessels with certain criteria.

Please see attached below.

Below is the table to describe more on our data structure

If any VES_NAME & VOYAGE with SEQ = 1 and BOX + CARGO > 0 will count as 1 only, even it has SEQ 2.

For VES_NAME & VOYAGE with SEQ = 1 only and BOX + CARGO = 0 will no count. (1 record only)

For VES_NAME & VOYAGE with SEQ = 1 and BOX + CARGO = 0, but in SEQ = 2 or more, if the Sum(BOX + CARGO) > 0, will have only count as 1 also.

Mean: Count is distinct by VES_NAME & VOYAGE, and Sum(BOX + CARGO) > 0.

Hence based on our qvw below, is there any way we can get the answer on the text box

YYYYMM	VES_NAME	VOYAGE	SEQ	ATB	GATEWAY	V_TYPE	BOX	CARGO	REMARKS
201501	VESNAME 01	VOY01	1	07/01/2015 10:30:00	X	BARGE	0	0	No count, only Seq 1 and Box + Cargo is 0

Bennn, Your requirement is clear. Can you explain in brief.

Hi,

our records will show vessels that berth on our terminals. However we will have two records of the same vessel is the vessel will to berth Twice. Hence our counting of vessels should show as 1 rather than 2 with the same vessel voyage as the primary key identifier.
