Inv_AeX_SWD_Execution_Summary table is not getting updated.

In SMP 7.1 SP2 MP1 the table “Inv_AeX_SWD_Execution_Summary” is not getting updated in our Altiris Database. This table is required to track the status of Software delivery and Patch management. Inventory is running up to date (Full inventory/Hardware/software) and getting updated Add remove table and other tables too. I checked log files and found that there is an issue with Task servers, The TS was older version and have upgrdaed to newer version,but still this table is not getting updated. Any idea?
