Update table' s values in loop


my issue is to process data in a table using a loop that replaces some values in my table during the iterations.

For instance, I have a 100 rows table of numeric values.

In the first iteration of the loop, I read the rows from 1st to 90th to compute the value of the 91th row.

The 91th value is used to create the input data for the 2nd iteration, in which data has 91 rows, in order to compute the value of the 92th, and so on.

The loop continues until a stopping criterion.

To do this, I used a Generic Loop Start that reads data from Table Read, processes data, writes data using Table Write and ends by Variable Loop Condition (see attachment).

I was wondering if there is a better way to update data in the table during its processing using different nodes, instead of Table Write and Table Read.

Thanks in advance,


Hi Alessandra,

this is what the Recursive Loops can be used for. We also have a short video about them on youtube: https://www.youtube.com/watch?v=0zhDVBd2ihk
