With the exception of Enable Impact Report and Enable Execution Flow, you should select all of the Perform Program Analysis options you are going to need for Cobol program analysis the first time you collect analysis information, whether during verification or subsequent post-verification analysis.This is because, with the exception of Enable Impact Report and Enable Execution Flow, selecting any of the options dependent on the Perform Program Analysis project verification option, whether during a previous verification or a previous program analysis, results in none of the information for those options being collected in a subsequent post-verification program analysis.
Therefore if you verify a program with the Resolve Decisions Automatically option selected, then perform a subsequent program analysis with the Perform Generic API Analysis option selected, API analysis information is not collected, whereas if you perform the subsequent program analysis with the Enable Impact Report option selected, impact analysis information is collected.
Similarly, if you perform program analysis with the Enable Impact Report option selected, then perform a subsequent program analysis with the Enable Parameterization of Components option selected, no parameterization information is collected, whereas if you perform the subsequent program analysis with the Enable Execution Flow option selected, execution flow information is collected.
