Understanding how tFlowToIterate and tFixedFlowInput

Anonymous — Sat, 16 Nov 2024 10:20:33 GMT

Hello,
I have gone through the documentation for above two components, but I still did not able to understand how they
work and what is the usecase.
Can somebody please tell me using some raw data .
Eg :
csv file :
1,name,lastname,email
2,name2,lastname2,email2
|
|
tFlowToIterate (takes line number 1)
|
|
output from tFlowToIterate : xxxxxxxx
also I want to know how both work together.
Thank you

tFixedFlowInput - for pre-defined, fixed set of data,
tFlowToIterate - store Flow data to variable, then You can access any variable as (Type)globalMap.get("VariableName")
they can work together as - You define small table in tFixedFlowInput -> make a loop by tFlowToIterate -> use this variables on next steps which will repeated for any number of rows in tFixedFlowInput
