Replacing a value in a transformation expression, by typing manually a number within the "Text Box"

[Yahya Hafez]

We classified our data into three groups by creating a new columns (using Transformation).

Three constants were defined within the "Expression" of the Transformation that would decide the classification number of each row to be 1, 2 or 3, stored in the new column.

Now, every user wants to enter his own constants manually via Text Box in order to alter the classification thresholds.

How is it possible to use the Text Box to register a number that would alter a variable in the Transformations Expression

 

In other words, I need to update a calculated column by entering a number inside the Text Box

Create new Property in the Text Box, then use it in the Transfonrmation's Expression. Need to Upload Data afterwards.
