Data Correlation: Failed Substitution Reference[%1] Substitution[%2]
Details: A failed reference occurred in a prior request. Since
the reference named [%3] was null, we were unable to substitute a
new value for the substituter named [%4], original string [%5] at
offset [%6] and this request may have failed. Please inspect prior
requests for the reference failure and corrective guidance to avoid
this in the future. For more information search the help for the
data correlation topics.
Explanation
A reference for an expected data substitution is null.
System action
None.
User response
To find the failed reference, open the test and go
to the substitution site. Right-click the substitution site and select
Go To > Reference. When troubleshooting failed references, start
with the first error message. The first failed reference can cause
subsequent failed references. Search the test log for unable to extract
to find the first error message. Examine the request that generated
the response. The request contains a value that might need to be correlated.
For example, the request might contain a username that must be unique
to play back the test successfully. In that case, use a datapool to
provide a list of unique username values. You might need to manually
correlate a value by using the Test Data Sources view. Values that
typically are correlated include timestamps, dates, ID, and other
alphanumeric strings. If you no longer need the data correlation mentioned
in the message, remove that data correlation from the test.
