After upgrade to SRM_SERVER(SAPKIBKV19) the item table in view V_SC_DOTC_BASIC included no MasterColumn. Instead it holds an column which was changed after upgrade from MasterColumn to RowArrangement. This fails in the methode "/SAPSRM/IF_CLL_DOTM_SC_I_BD~INIT_ITEM_TOOLBAR" with a dump on case "lc_only_num" (Item numbering is customized) because there was no MasterColumn defined.
The solution(workaround) was to define a "dummy" Mastercolumn...
