Answer / jagadish
update strategy transformation is used to perform DML
operations for the already data populated targets.
by default informatica server will treat source row as
INSERT.if you use update strategy transformation in your
mapping the informatica server will treat source row as
DATA DRIVEN.so the datas transferd to a target that even
populated with some data can be inserted,updated,rejected
and deleted.based upon the functions like
dd_insert,dd_update,dd_reject,dd_delete you define in the
update strategy transformation.

Answer / obulreddy.b
IT IS A TRANSFORMATION WHICH IS USED TO PERFORM DML
OPERATIONS ON ALREADY DATA POPULATED TARGETS.
GENERALLY INFORMATICA SERVER WILL TREAT SOURCE ROWS AS
INSERT. IF WE USE UPDATE STRATOGY TRANSFORMATION WE HAVE TO
SELECT TREAT SOURCE ROWS AS DATADRIVEN IN SESSION
PROPERTIES, NOW INFORMATICA SERVER DRIVES THE DATA AS PER
UPDATE STRATOGY VALUE.
WE HAVE TO SELECT UPDATE STRATOGY VALUE BASED ON OUR
REQUIREMENT.

There are 2 files, Master and User. We need to compare 2 files and prepare a output log file which lists out missing Rolename for each UserName between Master and User file. Please find the sample data- MASTER.csv ---------- Org|Tmp_UsrID|ShortMark|Rolename ---|---------|----------|------------ AUS|0_ABC_PW |ABC PW |ABC Admin PW AUS|0_ABC_PW |ABC PW |MT Deny all GBR|0_EDT_SEC|CR Edit |Editor GBR|0_EDT_SEC|CR Edit |SEC MT103 GBR|0_EDT_SEC|CR Edit |AB User USER.csv -------- Org|UserName|ShortMark|Rolename ---|--------|---------|------------ AUS|charls |ABC PW |ABC Admin PW AUS|amudha |ABC PW |MT Deny all GBR|sandya |CR Edit |Editor GBR|sandya |CR Edit |SEC MT103 GBR|sandya |CR Edit |AB User GBR|sarkar |CR Edit |Editor GBR|sarkar |CR Edit |SEC MT103 Required Output file: --------------------- Org|Tmp_UsrID|UserName|Rolename |Code ---|---------|--------|------------|-------- AUS|0_ABC_PW |charls |ABC Admin PW|MATCH AUS|0_ABC_PW |charls |MT Deny all |MISSING AUS|0_ABC_PW |amudha |ABC Admin PW|MISSING AUS|0_ABC_PW |amudha |MT Deny all |MATCH GBR|0_EDT_SEC|sandya |Editor |MATCH GBR|0_EDT_SEC|sandya |SEC MT103 |MATCH GBR|0_EDT_SEC|sandya |AB User |MATCH GBR|0_EDT_SEC|sarkar |Editor |MATCH GBR|0_EDT_SEC|sarkar |SEC MT103 |MATCH GBR|0_EDT_SEC|sarkar |AB User |MISSING Both the files are mapped through Organization, Shor_mark. So, based on each Organization, Short_Mark, for each UserName from User.csv, we need to find the Matching and Missing Rolename. I am able to bring Matching records in the output. But really I don't find any concept or logic to achieve "MISSING" records which are present in Master and not in User.csv for each UserName. Please help out guys. Let me know if you need any more information. Note:- In User.csv file, there are n number of Organization, under which n number Shortmark comes which has n number of UserName.
