When merging refernce files into master file the level names will have the reference file name prepended in the name. How can these names be removed when merging reference file?
The "Copy Levels During Copy" setting controls if new levels created in the master file have the reference file name included.
Be mindful that if the level does exist in both master and reference, that the master file level is written to the level table first and therefore will control the level on/off mask display. This can cause problems when levels display for the same level names when the on/off display is different in the master files and reference file.
Use MS_MERGE_DISPLAYEDLEVELSONLY = 1 configuration variable to avoid copying through levels that are turned off when merging references.
