How to add custom method before saving like if that method will succeed then call the save if error then show some error message in recordlistview saving in cell

Hello Jurie Tylier Pedrogas , 

Based on your description, I believe you will benefit from reviewing the field validation documentation available here:

https://support.sugarcrm.com/documentation/sugar_developer/sugar_developer_guide_14.1/cookbook/adding_field_validation_to_the_record_view/

That will be specific of the record view. 

If this doesn’t address your needs, could you clarify the specific business problem you’re trying to solve?
This will help us provide a more informed and tailored answer.
I am considering the dependency actions that might cover your use-case. 

I hope this helps, 

Cheers, 

André
