# This example creates new line item creative associations (LICAs) for an
# existing line item and a set of creative ids. For small business networks,
# the creative ids must represent new or copied creatives as creatives cannot
# be used for more than one line item. For premium solution networks, the
# creative ids can represent any creatvie. To copy creatives, run
# copy_image_creatives.rb. To determine which LICAs exist, run get_all_licas.rb.
