We are enabling the auto-assignment by location . For this, I need to load local and groups in various categories. I intend to use pdm_load to load in mass groups and location of each category (see figure below). In the Ref. Tech manual, i identified that these are the fields "service_grps " and " service_locs" in prob_categoy, but they are BREL type , these fields are not displayed when executed a pdm_extract in prob_category . Does anyone have any idea how we can load these data in mass ?
