This stored procedure which is updating same table thrice with joins with other table is not running properly. sometimes it is only updating ABOR data and sometimes it is updating only IBOR data. sometimes it update FUND_IMPACT column, other times don't execute it at all. Please suggest why it is behaving like that. Timeout is set as 600 ms.

I suspect there could be multiple reasons for that
1. Row Locking - If multiple updates are trying to modify the same rows, there could be a row lock that prevents one of the updates from proceeding.
2. Each update statement has a Where clause, if one of the condition in the where clause does not match any rows, the update will be skipped for those rows. It could cascade down to further updates too
3. If there are triggers on the table that are executing as a result of the UPDATE statements, they might cause unexpected behavior such as skipping rows or modifying the table in a way that affects subsequent updates.
UPDATE
I would advise you to try having three similar test tables and test data for BREAKS, ABOR and IBOR. Modify the stored procedure to update these test tables. And then you can try testing and debugging to point out exactly what is happening exactly with the procedure.
I think #2 is the most likely option.
when i am running these three update statements in stored procedure, it is updating only IBOR_TOTAL_NET_ASSETS_USD and ABOR_TOTAL_NET_ASSETS_USD but not updating Break_BP_Impact and FUND_BP_IMPACT column, they are all 0.0000 or null. But when I run these three update statements separately one by one in sequence in SQL manually, it is working correctly and updating all columns. Why it is not working in the stored procedure????
