Previous Session/Scenario/Package details in ODI ( oracle data Integrator)

odiRef.getPrevStepLog: oracle data Integrator


In this artice i will try to explain how to extract the log/details for mutiple scenarios in ODI.
What is odiRef.getPrevStepLog ?
This ODI inbuilt function helps to identify or create reports at package/scenario level.
odiRef.getPrevStepLog : Returns information about the most recently executed step in a package. The information requested is specified through the parameter. If there is no previous step (for example, if the getPrevStepLog step is executed from outside a package), the exception "No previous step" is raised. 


I will try to explain one of the scenario where it can be used.
for an example suppose I have a main package/scenario "COPY_OF_PKG_LOAD_SUZ_CORNERSTONE" which includes/calls  Scenario "COPY_OF_PKG_SUZ_ORA_PGSQL version 001".

I want to create the log for the Scenario "COPY_OF_PKG_SUZ_ORA_PGSQL version 001".
Add these codes (in the image below )in the email body ( the mail notification step which i have already posted in previous article "Email Reporting in ODI" )  or the ouput log file & add it to the main pacakage "COPY_OF_PKG_LOAD_SUZ_CORNERSTONE"



I have added these deatils in my SUCCESS & FAILURE notification email step and added it to the main package "COPY_OF_PKG_LOAD_SUZ_CORNERSTONE"
