Errors in Joining QVD Files

How can I join multiple QVDs and specify the direction of the joins when the QVDs come from multiple sources and are created in the load script itself.

We are using Qlik Sense Feb 2022 edition running on Qlik Sense Server 14.54.2. I have a data set that consists of two queries and two google sheets and one attached xlsx sheet all of which I am loading into qvds. The ask is to link up old ids with new ids using a translation sheet that has fields of old_id, new_id, and old-new-id. Qlik keeps 'helping' by making a $Syn1 table and key that is completely ruining the return data set by returning None of the old_id records match up with their new_id counterparts from the transfer sheet. When I try to force the joins I get a 'field not found' error when it is clearly in the load scripts. I cannot share the actual script so I've prepared some mock-ups in the thread.

Option 1 qvd loader:

Option 1:

returning None of the old_id records match up with their new_id counterparts from the transfer sheet

//load query-a
 [query-a]:
 LOAD
   id_orig, 
   new_id,
    owner,
   item,
   transaction
 FROM [lib://My_Folder/query-a.qvd]
 (qvd);
 //load query-b
 [query-b]:
 NoConcatenate
 LOAD
    id_orig,
    new_id,
    owner,
    item,
    transaction
 FROM [lib://My_Folder/query-b.qvd]
 (qvd);
 //sheet-a qvd
 [sheet-a]:
 LOAD
    new_id,
    name
    
 FROM [lib://My_Folder/sheet-a.qvd]
 (qvd);
 //sheet-b qvd
 [sheet-b]:
 LOAD
    new_id,
   date
  
 FROM [lib://My_Folder/sheet-b.qvd]
 (qvd);
 //transfer_sheet qvd
 [transfer_sheet]:
 LOAD
    new_id,
    old_id,
  old-new-id
    
 FROM [lib://My_Folder/transfer_sheet.qvd]
 (qvd);

Option 2 qvd loader:

Option 2 produces an error like:

Results in fail to load error:
field new_id not found
near FROM [lib://My_Folder/sheet-b.qvd]

//sheet-a qvd
 [sheet-a]:

    new_id,

 order by a.item desc

From a
Order by ranker desc

store [query-a] into [lib://My_Folder/query-a.qvd];
drop table [query-a];

Hi, based on the arged model, doing a left join of both querys to trannsffer sheet ends with double fields for owner, item and transaction, so one of the table fields should be renamed.

The other option is to add rows from query A and Query B to be loaded you can do it as:

// LOAD query A data Table: LOAD * FROM TransferSheet; LEft Join LOAd new_id, owner, item, transaction From QueryA; // LOAD query B data in a different table to join with transfer and add the data to the previous table tmpTableB: NoConcatenate LOAD * FROM TransferSheet; LEft Join LOAd old_id, owner, item, transaction From QueryB; Concatenate (Table) LOAD * Resident tmpTableB; DROP Table tmpTAbleB; // Add sheet data Inner Join LOAD new_id, date FROM SheetA; Inner Join LOAD new_id, name FROM SheetB;
