Answer Posted / shar
we use parameters for flexibility,re-usability in job design, values hard coding is a bad habit and bad practice.
lets say u have 20 fields and u have to pass them every time as and when data processing demands. Then every time going into the job and modifying the values is an unprofessional way and we sometime commit typographical errors.
instead of that use job parameters for reusability and we can use them any where flexibly depends on the parameters created at job level or project level.
