Why parameterization and correlation are required
Parameterization and correlation are required for unique/dynamic
values that are generated by the server. In the case of PowerServer,
the access token, session ID, and transaction ID are all
unique/dynamic values generated by PowerServer at runtime. If you
re-play the scripts without first changing the value recorded, the
scripts will fail, because the dynamic value generated by PowerServer
does not match with the value recorded.
Therefore, after the scripts are recorded, you need to find out
all occurrences of the access token, session ID, and transaction ID in
the script and replace them with variables.
In some cases, dynamic values also refer to the retrieval
arguments, ESQL parameters etc.
