Content (required):

Hi All,

We have approximately 30 thousand transactions in our PROD environment which contains approximately 45 - 50 thousand transaction lines in them collectively. BS Id of those transactions along with the respective document number details of the line items is also stored in some of our data tables in CPQ.

Now the requirement is that we need to send some particular data , for each of the line item we have in our PROD, to some 3rd system, by invoking a simple action ( behind which a simple integration is called via BML script ).
