How to fix this error?

This process can be influenced by the RSADMIN parameter
RSDD_LM_JOIN_ANALYSIS. The following cases have to be taken into
account.
Table RSADMIN does not contain RSDD_LM_JOIN_ANALYSIS at all.
The analysis will be interrupted if more than 10000 distinct values are
found (default value).
Table RSADMIN contains RSDD_LM_JOIN_ANALYSIS.
If the value for RSDD_LM_JOIN_ANALYSIS is empty (blank), the analysis
runs until it has finished or the limit for profile parameter
rdisp/max_wprun_time is exceeded.
If a value has been assigned to RSDD_LM_JOIN_ANALYSIS ? 500 for example
? the analysis will be interrupted as soon as the investigated join
contains more than 500 distinct values.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
