Hi,

you can use a dummy table that is being created in front of your extraction that only contains the dynamic start date in it. e.g:

DROP TABLE IF EXISTS TMP_DYN_START_DATE;

CREATE TABLE TMP_DYN_START_DATE AS (

    SELECT TIMESTAMPADD (YY, -2, (ROUND(CURRENT_DATE, 'MM')))

);

Use the TMP table within your dynamic Data Pool Parameter and use this parameter within your Data Extractions as date filter.

Use the dynamic parameters. Take the "ROLLING_START_DATE" from your required table and set it as a data pool parameter. In a separate transformation, make the ROLLING_START_DATE to be <= ADD_MONTHS(__, 18).

In a transformation of the you can create the table Extraction_Start referenced in the parameter.  

That is exactly what I recommended... :)

Thanks a lot !
