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

Himanshu_PantHimanshu_Pant Member Posts: 30 Contributor I
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'

    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.

    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.
  • Himanshu_PantHimanshu_Pant Member Posts: 30 Contributor I
    This method worked. However, while using this macro in 'Create Example Set" getting wrong Date format error.

    Hi,
    likely you need to adjust the date format setting? or maybe its because Marco had a spelling error with only 3 y's.

    Hi @mschmitz,

    Adding the process. Please have a look.
  • mschmitzmschmitz Administrator, Moderator, Employee, RapidMiner Certified Analyst, RapidMiner Certified Expert, University Professor Posts: 2,982  RM Data Scientist
    Hi,
    can you try Extract Macro (Format) from operator toolbox? It allows you to specify the date format manually.

    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)
