Unable to select (current field name +1) in Multi-Field tool

[Nipun_Charaya]

I need to apply a calculation which compares the date of current and next field name. How could I choose next field name as a variable in my Multi-Field expression?

As @Raj mentioned, more information would be very helpful in providing guidance for your particular problem: a more detailed problem description, sample input and output (not images is ideal).

That being said, there is no way for the Multi-Field Formula Tool to dynamically reference the next column in the dataset. You only have access to the Current Field, and Original Fields (which must be accessed by name).

If you just need to compare two date fields in different columns, I recommend just using a Formula Tool. If you have a series of dates that need to be compared from one column to the next, then you would be better off transposing the data and plugging in the Multi-Row Formula Tool.

While you can technically write a large nested if statement to check the current field name and then perform the correct comparison, this would only work for a small fixed number of comparisons would be hard to read/debug, and is highly not recommended.

Hopefully this helps and Happy Solving!

I guess this helps and answers my question. Thank you. However, if I get stuck will share the more information. For now I will transpose and use the Multi-Row formula tool.
