During a reference update, the program can search the referenced files in the order in which they are listed on the References tab, and then update the target file with the first instance of each referenced resource that is found.
If the same resource exists in multiple referenced master files, it is recommended that you disable this feature. Otherwise, if you change the priority order, or if you update an individual reference, you could change the source file of a resource inadvertently. To prevent this from happening, deselect the option to Use reference priority when updating resources in the Reference Settings dialog box (see Setting the Referencing Options).
To set the priority of referenced files:
Select Tools > Organization to open the Organization dialog box.
From the References tab, click Settings to open the Reference Settings dialog box, and ensure that the option to Use reference priority when updating resources is selected.
From the References tab, click the number in its # column to select the master reference file to be moved; drag the item up or down the list to the new priority position. The first file listed on the References tab has the highest priority.
