In this scenario we are trying to pull data from adobe cloud and save it in AWS S3 bucket as a pipe delimited file.
You should use scheduler available within the incremental query activity.
If this is not possible for some reasons then you can use scheduler +JS to keep track of the last execution date and a standard query activity to use that execution date from JS in a workflow.
let me reiterate the problem.
1. let's say customer wants to extract the data from 1st Jan to till now [18th Jan] and first time workflow was ran on 14th hence the data till 14th was exported.
2. Next time workflow ran on 15th so rather than sending out the data from 1-15 Jan, you want to export the data post 14 Jan[ last execution] but before 15 Jan, right?
create a option with name last run
once this is created put a scheduler and write a js code to read the option.
1.schedule to trigger the workflow everyday.
2. JS code- read option and store last run date and also getCurrentdate() on two separate event variable.
3.pass the last run date in query activity like : last modified data on or after $datetime(vars/@lastRepDate)
4. Once done then update the option using code: setOption(vars.optionName, vars.nextRepDate); // added on end activity advanced tab.
