Merging direction is the opposite of what was expected

Question

In ./xxx01/tab/tab_merge_overlay column 2 is defined in the following way:

! COL 2. 1; NUM{1,2}; ;
! Merging direction;
! Merging direction:
! 1: refers to the database record
! 2: refers to the record in the incoming load file

When merging 2 records, one from an input file and the other from the database, the direction of the merge acts the opposite. Why?

Answer

See also header of ./xxx01/tab/tab_merge

! Note: when running file-99, file-93, manage-18
! and oclc_server with merge_doc_overlay or
! tab_merge_adv_overlay, the preferred
! record is the record in the incoming load file.
! In order to change direction add preferred_doc_switch
! to tab_preferred; it changes the direction
! and switches between the preferred and
! the non-preferred records.

This applies also to Advanced Generic Vendor Records Loader (file-90) and also Load OCLC Records (file-93)

Additional Information

Merge direction can be changed according entry in ./xxx01/tab/tab_preferred
