Hi Fred,
Thanks for replying.
The PI for INV_SVC_ACCT is SVC_ACCT_SK (Surrogate Key). The target table PI was TLFR_CORP_ID but now it is changed to TLFR_NUM which is being populated from TOLL_FREE_LINE table.
The code is still simplified by the use of different temp tables that now holds the data after using common joins (like ACCT_DTL which holds data related to account like address, contact etc.,.). I also wrote two inserts which in turn will try to load the data in smaller chunks (i.e., 25 million on an avg). But still I face this spool issue at one insert (the one which has to load 25 million records).
Now, Overall record count should be 43 million.
