Answer / shar

see parallel jobs r by default optimized such that transformer stages only get recompiled if they have changed since the last compile. The force compile option overrides this and causes all transformer stages in the job to be compiled

Answer / bhupathi reddy

you have done some changes in satage properties (i.e some business logic has been changed)which has already ran job , if u compile the job the compilation would be effect on which ever u modfied (i.e in recent changed stages).when ever you do the force compilation entire job will compile again .
