Always use a CAST AIP setup installation. For reproducing issues, flat installation is not recommended because the analysis/snapshot may fail. This can be due to files that are missing in the flat installation.
Import the databases mngt and local if reproducing the analysis issue else import all the three bases for snapshot issue.
Map the source code path in order to respect the deployment defined in configuration.
Go to the current Version tab and check the path of AU whether it is mapped to the same path of the deployment folder.
If customer provides the complete source code then the complete source code should be in the mapped deploy folder, refer this page before you proceed with the analysis, this page gives the prerequisites for the installation of third party software before analyzing Oracle Forms analysis.
Configure DLM only if the issue is related to DLM. If not required delete it from CAST-MS because while configuring the analysis you might not have the dlm.xml file, for more info please refer thispage
Only if the issue is related to missing links and reference pattern, configure reference pattern otherwise remove it from CAST-MS, for more info please refer thispage
If you don't require the settings in"Tools before analysis" and "Tools after analysis" for your reproduction then remove these configurations from Content enrichment tab in CAST-MS, for more info, please refer this page
Uncheck the analysis units of other technologies, if you have other technologies apart from the technology that is being analyzed but in case of missing links between inter technologies (for ex: missing links between java method and oracle table) you have to be careful while un-checking the analysis units of other technologies. This will shorten down the analysis run time, for more info, please refer this page
If Architecture model is configured, the same configuration should be made, for more info, please refer this page
Check all the tabs in the CAST-MS for different configuration done by customer, make sure you have the same configuration otherwise your analysis will fail at some other step and you will end up with different issue.
