Qlikview "links" tables by means of fieldnames. As there are no common field names to the two tables, they will not be associated in any way. You can rename fields in the second table by
LOAD @1 As Key, .....
The usual design of a QV data model has a single key field common to the two tables. Multiple common fields will cause synthetic keys and/or data loops unless you join or concatenate the data.
In this case, it looks like you should join the data to the source table, but you will need to reconstruct the DocLocation in the second table, something like:
LOAD @1 & If(Len(@2)>0, '/' & @2) & If(Len(@3)>0, '/' & @3) & .... & If(Len(@8)>0, '/' & @8) As DocLocation,
Hope that helps
