Transform map - User defined variable for all rows

lakshmin — Wed, 01 Oct 2025 02:16:42 GMT

HI team

I would like to read a System property from a Transform map and store it in a user defined variable

ex - allowedlistsysprop and have the variable available for all row transformations

Basically i have a list of allowed matches in a system property and would like to do string match something like below for each row

if (source.myfield1.indexOf(allowedlistsysprop) != -1) { //do something }

I would read the property only once and can define the variable in an onStart script .But not sure how to properly define it in onStart script and access it in each of the OnBefore script and more important make sure the variable doesn't leak into any other process .

i am reading some references setting it as a global variable using onStart script . But how do i make sure the variable doesnt spam other processing .Appreciate any guidance around this

Thanks in advance

Lakshmi
