Qlikview Loop Iteration function - ProjectID key

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.

Any suggestions? 

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

Thanks,

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

1- ProjectID2 - 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)
PROJ1PROJ2  PROJ2
PROJ3PROJ4PROJ5 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,

I'm sorry, but I didn't completely understand the objective.

you get the table

1- ProjectID2 - 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)

and you want to add :

Leader2doc (the very first leader - EXPECTED)

if so what's the rule?

Hey,

The rule is some kind of loop for every ProjectID:

(BRI_SUBPROJM  is the leader of  the ProjectID)

while (BRI_SUBPROJM contain value (ProjectID),  iterate it.

once the BRI_SUBPROJM contain 0, pull out the very first ProjectID - the leader.
