Dear M D
no clue waht you have done and what your problem might be, I can inly imagine. Therefore:
If you would like to print a label in GLM transaction you need a material; the material must be linked to a specifiacioin, the specification should hav e suitable genvar/language combination released and you need to have prepared LabelView. If oyu have done itr like that the "LabelDetermintation" can run.
