Qlikview Loop Iteration function- ProjectID

[idodel]

Hello Qliks! 

I have a Projects table that contain ProjectID field & might have a another project who leads the same Project above the first.

exists: -left joins the DOC for checking, not in infinite way. 

left Join
LOAD
DOC as Leader1doc ,
If(BRI_SUBPROJM<>0,BRI_SUBPROJM,DOC) as Leader2doc
FROM [Data\DOCPROJ.qvd] (qvd);

demand: Building a loop iteration that pulls out the very first ProjectID that doesn't contain any leader.

BRI_SUBPROJM<>0 - checking if the ProjectID has any leader.

hope it will make sense, Table after some left joins:

1- ProjectID	2 - BRI_SUBPROJM (the Leader Project - if exists)	3- BRI_SUBPROJM (the Leader Project of 2 -if exists)	4- BRI_SUBPROJM (the Leader Project of 3- if exists)	Leader2doc (the very first leader - EXPECTED)
PROJ1	PROJ2			PROJ2
PROJ3	PROJ4	PROJ5		PROJ5
PROJ6				PROJ6

Currently:  doing the search but not in a loop, and only brings the PROJ5 example.

We will have even more projects connected like 5 in row.

Thanks,

would you be able to share sample data?

CustomerID	ProjectID	Ctype	CtypeLeader2doc	Leader1doc	Leader2doc
12901	19V00072	Type1	Type2	19V01059	19P01100
19882	19J00035	Type1	Type2	19V01054	19P01103
19882	19N00008	Type1	Type2	19V01054	19P01103
19882	19J00043	Type1	Type2	19V01059	19P01100

The main purpose is to pull out the ctype value of the very first ProjectID - that contain null value on the BRI_SUBPROJM  field (in a Projects table)

Currently the search happens but not in a loop, and only brings the second leading project = Leader2doc.
