tIterateToFlow using a lot of columns

Alpha549 — Fri, 15 Nov 2024 23:00:44 GMT

Hello everyone,

When we use tFlowToIterate, we can set that it automatically create global variable using the input row :

However, this smart tips is not available for tIterateToFlow :

The least I can do is copying the schema from tFlowToIterate and paste it in tIterateToFlow.

Then I have to write the global value of each column.

What I want to know : if there are 40 columns (for example, to mean a lot). It's quite long writing the value manually.

Is there a kind of "auto mapping" ?

Thank you everyone 🙂

@Alpha549 Alpha549 , there is no auto mapping, this can be a new feature request. However, you don't need all columns for next processing sometimes.

Oh ok... I think that this feature would be REALLY great in a next version !

You're right, we don't always need all columns, but sometimes yeah we need them all haha
