Hi, I think that if the orginal table vhet.dh_subdeal_product_structure was created by SAS 9.1there could be some problems in reading it by SAS 9.3. If it is possible try creating a copy for example in work library by datastep data dh_subdeal_product_structure_copy; set vhet.dh_subdeal_product_structureů run; and try to run the query reading from this copy of your original dataset.
