Used join for the same tables multiple times, I want to limit the each table count to 1.

[Discaboota]

from RCA.VISIT_LOANACCOUNTS la
left join RCA.VISIT_FEEDBACK fb on Fb.Accountid=La.id 
left join RCA.VISIT_APPLICATIONORG ao on la.agencyid=ao.id 
left join RCA.VISIT_APPLICATIONUSER au on la.CollectorId=au.id 
left join RCA.VISIT_LOANACCOUNTS L on Fb.AccountId = L.Id
left join RCA.VISIT_APPLICATIONUSER auo on la.AllocationOwnerId=auo.id 
left join RCA.VISIT_APPLICATIONUSER auf on auf.id=fb.CreatedBy 
left join RCA.VISIT_APPLICATIONORG AOO on auf.BaseBranchId = AOO.Id 

I have used left join for 4 tables by repeating them twice or thrice. I want to use each table once and want to put the joins, but when I do that it shows that the below table has not been referenced yet. How can I do that it error free?

How the log look like? What is exact error message in the log?

[EDIT]

P.S. I'm asking about your log because in my sas session everything went smoothly:

code:

libname RCA (work);

data RCA.VISIT_LOANACCOUNTS;
  id=1;
  agencyid=1;
  CollectorId=1;
  AllocationOwnerId=1;
run;
data RCA.VISIT_FEEDBACK;
  Accountid=1;
  CreatedBy=1;
run;
data RCA.VISIT_APPLICATIONORG ;
  id =1;
run;
data RCA.VISIT_APPLICATIONUSER;
  id=1;
  BaseBranchId=1;
run;

proc sql feedback;
