Source:
customers table:
Customers table has data for columns cust_id, Year, City columns like below.

Prev city column need to be populated as the previous city like below.

Connect the columns to expression transformation and create columns as below:
CUST_ID (i/o)= CUST_ID
YAER (i/o)= YAER
CITY (i/o)= CITY
v_cust_id (variable)=v_prev_Cust_ID
v_old_city (variable)=v_prev_city
o_prev_City (output)=IIF(v_cust_id=v_prev_Cust_ID,v_old_city,null)
v_prev_city (variable)=CITY
v_prev_Cust_ID (variable)=CUST_ID

Hi Buddy,
ReplyDeleteAwesome article.

Hello There,
ReplyDeleteGreat info! I recently came across your blog and have been reading along.
I thought I would leave my first comment. I don’t know what to say except that I have
Good luck on your test and I'd be interested to hear your testing thoughts.
Almost all function specifications I've seen so far are intellectual property of the respective organisation.
But you can find some templates in Velocity, the Best Practices collection provided and maintained by Informatics Professional Services.
I read multiple articles and watched many videos about how to use this tool - and was still confused! Your instructions were easy to understand and made the process simple.
Ciao,

Hiya,
ReplyDeleteGreat post. Can’t get any more straight forward than this article. Thanks!
Lets suppose a consolidated record with multiple XREFS. There is non trust enabled column, which is populated in both the XREF and the recent one is surviving in BO as per the survivorship rules. Now, if a NULL update comes from source on one of these XREFS would it survive at BO? I know for Trust enabled columns, trust is automatically downgraded for NULL values, but how does this behave in non trust enabled columns?
Great effort, I wish I saw it earlier.
Muchas Gracias,
Irene Hynes
Hi Pradeep,
ReplyDeleteTHANKS SO MUCH for sharing this! I would love to buy you a coffee since I now won’t be up all night that has been driving me crazy (until now!!). I just wish I knew what was going wrong but so glad it’s in the right place now! Thanks again:)
The same case with the PUT API, while reating a PUT request we have to to provide PKEY_SRC_OBJECT (in case of update we can provide value for ROWID_OBJECT or for both). So, MDM will perform the check on PKEY_SRC_OBJECT, if it exits then update the record else will create a new record.
I look forward to see your next updates.
Obrigado,
Irene Hynes
Hello There,
ReplyDeleteThis is one awesome blog. Much thanks again. Fantastic.
while loading the data from stage to base object. on what basis I can say records get inserted or updated into the base objects. I guess my question is clear this time
It is like a usual database trigger, Informatica MDM Training you shall configure it in your Message trigger setup under schema in model workbench.
You can make the trigger generating events on changes happening on any of your custom columns (or) on any specific columns you choose.
You have a check box to specify if you want your trigger to generate notification only on some selected columns.
Great effort, I wish I saw it earlier.
Thank you,
Preethi.
Hi There,
ReplyDeleteThanks for the post. Very good details. Worked like a charm. Good directions.
Let's say your record coming from source A and it is highly trusted,
undergone match and merge and survived in BO with trust score.
After some point of time again your record coming from different source B Informatica MDM Training USA
which is having higher trust score and obviously it will find a match with
your existing record in BO and since source B is highly trusted it will
override the existing recrd in BO.
Once again thanks for your tutorial.
Many Thanks,
Irene Hynes
