	AB00081A000495	Nov-14 - Nov-15		7,450
	AB00081A000495	Total		145,550



TABLE 2
RISK	POLICY_NO	POLICY_PERIOD	PREMIUM
18-9714	AB00101A000656	Sep-10 - Sep-11	24,000
19-6047	AB00081A000495	Nov-08 - Nov-09	12,000

	AB00081A000495	Nov-14 - Nov-15	21,000

I want to join these tow tables to obtain the report as follows.

RISK	POLICY_NO	POLICY_PERIOD	CLAIM_NO	PAID_AMOUNT	Premium

Please note that premium should be shown in one row although There are several rows for claim payment. Pls advise me which type of join a I should have in my data model in order to achieve above output

Have you considered just concatenating the two tables using CONCATENATE LOAD prefix on the second table?

This will not reproduce the table on the bottom of your post, but might fulfill your analysis requirements as well (e.g. filtering on RISK, POLICY_NO or POLICY_PERIOD, and aggregating your PAID_AMOUNT and Premium correctly.

Thanks

Sorry I have made a mistake . The Risk field is not available in my second table. Therefore if I do concatenate I can not filter data on Risk field that is my main requirement. Pls advise

You can maybe use a MAPPING table created from the first table:

TABLE1:

LOAD

RISK,

POLICY_NO,

POLICY_PERIOD,

CLAIM_NO,

PAID_AMOUNT

FROM Table1Source;

RISKMAP:

MAPPING LOAD POLICY_NO, RISK RESIDENT TABLE1;

CONCATENATE (TABLE1)

LOAD ApplyMap('RISKMAP', POLICY_NO,'no mapping found') as RISK,

POLICY_NO,

POLICY_PERIOD,

PREMIUM

FROM Table2Source;

Or could a POLICY_NO have more than 1 RISK?
