GAM.BANK_ID,
TDS.REMITTANCE_DETAILS,
CMG.TDS_TBL_CODE,

SELECT *,

How long do the two queries take - is one a lot longer than the other?
How many rows in the temp table.
In your status query - select top 1 rather than distinct but don't think that will help much.

What are the PKs on GAM, TDS, CMG?
How long and how many rows from
select GAM.PK, TDS.PK, CMG.PK
into #a
from GAM
INNER JOIN TDS ON GAM.ACID = TDS.ACID AND GAM.BANK_ID = TDS.BANK_ID
INNER JOIN CMG ON GAM.CIF_ID = CMG.CIF_ID AND GAM.BANK_ID = CMG.BANK_ID
WHERE GAM.SCHM_TYPE = 'TDA'

==========================================
Cursors are useful if you don't know sql.
SSIS can be used in a similar way.
