Hi,I have 4 table in database, Now i have to add 1 column in one these table. I have modified my existing DD scipt regarding chnage of new column.But when i tried to edit any DCR and deploy values in database. all tables update properly but only modified table is not updating existing values.In log file error like "Table_name is already exist in Cache".Tuple formation is also correct. I have tried tried one trick to check where actual problem is.I have created new table and tried same deployement on these tables, its works successfully.from that i have come to know that issue is related to existing table cache only.I am using TS 6.7.2, OD 6.0.1, SQL 2005.Please tell me how can i clear existing cache for modified table.
