Character padding limit in expressions

[Abraham Smith]

Hello, I'm having a problem with expressions that I haven't encountered before, and I hope you can clarify my doubt.

I've been doing some translations using the "SUBSTITUTE" expression, based on a previous expression that takes as values ​​some acronyms from the name of the Composite or Complex Profile, also modeled with walls. The issue is that if I call another "SUBSTITUTE" expression, I get an "Unknown Error" which limits my ability to create a translation database for these acronyms, but I can't find a way to overcome that limit. See images below:

No errors

"Unknown Error"

I look forward to your comments. Regards

I wonder if it is the sheer number of nested functions in the Expression that is causing the error.

You could try reducing the number of SUBSTITUTE functions in the Expression and see if it works.

Or, you could start from the other direction: start with only 5-10 SUBSTITUTE functions and increase them gradually, see if you hit some limit where the error message starts occurring.

So, basically, you should start debugging the Expression.
