How to use iteration value in a extracted macro to generate another macro?

I have extracted a macro inside 'loop example'. The loop example is connected to dataset which contains dates. The data set has one attribute called 'Event DateTime_adjusted'. The macro {START_DATE} is extracting 'Event DateTime_adjusted' attribute value. Now I want to generate a macro using this formula :
date_add(%{START_DATE},eval(%{example_index}),DATE_UNIT_DAY).
But it is throwing an error: The function date_add must have an argument of type 'date'
date_add(%{START_DATE},eval(%{example_index}),DATE_UNIT_DAY).
But it is throwing an error: The function date_add must have an argument of type 'date'

attached is the fixed process. I hope it does what you want. The challenge you had, was the default time format we use for strings. I just used date_str_custom and Extract Macro (format) to use another one.Best,Martin<?xml version="1.0" encoding="UTF-8"?><process version="9.9.002">

Hi @Himanshu_Pant
You'll need to date parse the macro date you are using.
date_add(date_parse_custom(%{START_DATE},"yyy-MM-dd hh:mm:ss"),eval(%{example_index}),DATE_UNIT_DAY)
Just adjust your date string to your format.0 -
This method worked. However, while using this macro in 'Create Example Set" getting wrong Date format error.0
-
Hi,likely you need to adjust the date format setting? or maybe its because Marco had a spelling error with only 3 y's.Best,Martin0
-
-
Hi,can you try Extract Macro (Format) from operator toolbox? It allows you to specify the date format manually.Best,Martin0
-
Yes, but in extract macro I can't use the formula:
date_add(date_parse_custom(%{START_DATE},"yyy-MM-dd hh:mm:ss"),eval(%{example_index}),DATE_UNIT_DAY)
