How many levels we can dot walk using current Api in business rule?

In case many levels is that good practice to beyond two layers?

@KM SN 

you can dot-walk as many levels deep as necessary using the current API in a Business Rule. 

But it's generally not recommended to go beyond two levels of dot-walking in a Business Rule due to:

1. Performance Issues – Every dot-walked reference results in a database query. Too many queries can slow down your instance.
2. Null Values Risk – If any reference field is empty (null), the script may fail unless you handle it properly.
3. Readability & Maintainability – Deep dot-walking makes scripts harder to read, debug, and maintain.

Best Practices:

*Use GlideRecord Instead of Deep Dot-Walking If you need data beyond two levels, use a GlideRecord query instead of dot-walking.
