When critical differences exist in the target system which cause either mass technical errors or mass failures in the playback, it would be better to be more proactive regarding this rather than reactive when it is too late. Before a playback is started, Predictive Difference Analyzer (PDA) will review any differences between all relevant objects in the source system and those same objects in the target system.
Any “differences” between the objects compared are flagged up to the operator and are marked as either:
- Errors – Difference in target will cause issues during the playback
- Warnings – Differences to be aware of but not necessarily playback issues
The process for utilizing PDA is as follows:
- Navigate to PDA execution drawer item
- Click on the “Prepare” menu item (single threaded for small execution queues, Diffuser version for large queues)
- Run the preparation program for the execution queue (new run should appear)
- Select the run and choose “Compare” menu item. Single threaded or Diffuser option
- Once complete, double click the PDA run that has been analyzed and compared
- You can view a summary of what has been detected by PDA by object type. Alternatively, you can view a summary of all differences detected by the “failure reason” (tab 2). The last tab shows the results of PDA by individual object. Filters are available in all grids.
- For errors (or warnings) that are found, you can drill down to a list of these which provides additional information and further help or documentation. From there remediation can be triggered as well.
Remediation
It is possible to remediate the content (input/output container elements) of test scripts where PDA has detected a scenario which will cause errors or failures. This functionality only supports adding or replacing fields within containers (with default values) for dialog transactions and inbound RFC. It is triggered from remediation option when reviewing the results of the comparison
