Objective of Preview Mode in Mass Programs
Does the program in preview mode do any validations or calculations etc?
I did not see it doing much .. for e.g
a) Try to do a mass transfer of a set of asset from one expense account to another ( ensure the target account is disabled or invalid)
b) When you run the preview mode, the program does not error
c) Now when you click on Run for the mass transaction, program will error saying the target expense code combiantion is not valid/exist etc
