Please let me know how we can implement the below scenario.
In a single mapping,more than 500 sources
(legacy,VSAM,relational) will be loading into only one
target. Whenever I retreive the data(any record) from
target, i need to find the details that the record belongs
to which source.
Thanks in advance..

Here i am assuming that your single warehouse table has
data from more than one source,and you need to distinguish
the data among the sources.
For this to accomplish you can have table which can have 2
columns Datasourcename and ID.This table will have all the
source list and ID column will be the surrogate key.
Now you need to alter your warehouse table by adding a new
column called Source Identifier.
Now you have the architecture ready.
When loading your warehouse table just look up the first
table for the source name and pickup the corresponding
surrogate key and populate into the Source identifier
column in the warehouse table.Use this Column(Source
Identifier)to identify the sources.

if u r using informatica 8.0 n above u have a option to
load the name of the file. this is in the sq itself just
check the currently processed file name box. remember this
will give u the complete path of the file, hence u need to
substring it before loading it to tgt

Answer / arnab
create a system where you can identify a source with an
ID.you may call it as datasource_num_id , build a cross
reference table to store all tis information , in the map
you can use this cross reference table to get the ID and
populate this id in ur target table

Answer / vdiwade
Yes its possible through above logic…In addition to Srinu
idea....you can understand very easy way. Suppose creare one
(specific src) insert script.. means for 500 sources,500
insert script,which loads data into one src/tgt…we can add
one more column source_name tht will be always coming
source_name..so at the time of retrieving we can easily
understand this records belongs which source/tgt tbl.

Hi all, i am new to this site and new to Informatica too. I have few questions regarding that. 1) When we load flat files into target tables how do we identify duplicates? and where do load the duplicate records for further reference? 2) How do we do chage data capture? Is this Slowly changing Dimension technique? Thanks in Advance
How can the following be achieved in 1 single Informatica Mapping. * If the Header table record has error value(NULL) then those records and the corresponding child records in the SUBHEAD and DETAIL tables should also not be loaded into the target(TARGET1,TARGET 2 or TARGET3). * If the HEADER table record is valid, but the SUBHEAD or DETAIL table record has an error value (NULL) then the no data should be loaded into the target TARGET1,TARGET 2 or TARGET3. * If the HEADER table record is valid and the SUBHEAD or DETAIL table record also has valid records only then the data should be loaded into the target TARGET1,TARGET 2 and TARGET3. =================================================== HEADER COL1 COL2 COL3 COL5 COL6 1 ABC NULL NULL CITY1 2 XYZ 456 TUBE CITY2 3 GTD 564 PIN CITY3 SUBHEAD COL1 COL2 COL3 COL5 COL6 1 1001 VAL3 748 543 1 1002 VAL4 33 22 1 1003 VAL6 23 11 2 2001 AAP1 334 443 2 2002 AAP2 44 22 3 3001 RAD2 NULL 33 3 3002 RAD3 NULL 234 3 3003 RAD4 83 31 DETAIL COL1 COL2 COL3 COL5 COL6 1 D001 TXX2 748 543 1 D002 TXX3 33 22 1 D003 TXX4 23 11 2 D001 PXX2 56 224 2 D002 PXX3 666 332 ======================================================== TARGET1 2 XYZ 456 TUBE CITY2 TARGET2 2 2001 AAP1 334 443 2 2002 AAP2 44 22 TARGET3 2 D001 PXX2 56 224 2 D002 PXX3 666 332
