    Additional tree branches exist"

    • Article Type: General
    • Product: Aleph
    • Product Version: 20, 21, 22, 23

    Description:
    In the navigation pane, this message occurs under SYS60 for this record. ADM is NSU50. Bib sys# is 1261866.
    There appears to be no way to determine what the additional tree branches are, or how they came to happen.

    Resolution:
    There is a limit to the displayable tree branches, this depends on $alephe_root/pc_server_defaults, with a combination of these value:

    1.2 Tree View Display
    The following line in the table refers to Search function and cataloging module Tree View settings:
    setenv pc_tree_view_max_branch 99
    pc_tree_view_max_branch defines the limit after which the display of the navigation tree nodes in the Cataloging module and in the Overview tree of the Search tab is truncated with an appropriate message. This parameter limits either the number of ADM or HOL links of the given BIB record. If it is set to 5, only 5 ADM records that are linked to this BIB are displayed. The following parameter:
    setenv pc_filter_tree_view_max_branch 99
    defines the limit after which the display of the children of the navigation tree nodes in the Overview tree are truncated with an appropriate message. If both parameters exist, you will be able to see more information. In both cases the trees are limited to 800 lines.

     

    [QUOTED from the ALEPH System Librarian Guide - Search]

     

    As noted in pc_server_defaults in v20 -up:

     

      #       pc_tree_view_max_branch and pc_filter_tree_view_max_branch
      #       must be in the range 1-750.

     

    More:
    You can only configure up to 750 items, holding records, adm records, per linked bib record. So if you have 2000 items linked to a HOL record, only the first 750 display. But, if you have 10 HOL records and each has 1000 items linked, you will only see a total of 800 lines on the Navigation pane, even though you've said 750 records per node. The Navigation Pane can only handle 800 lines of display.

     

    If you need to move an order from one record to another and even with the max of 750 the record is not displaying, the move would need to be performed via SQL.
