The new keyword mapping cannot be saved because the previous mapping could not be removed.
Explanation
More than one previous Solution Manager keyword mapping was found in the connector database. To update keywords, the connector database must contain only one set of previous keywords.
Programmer response
Ensure that keyword information is correct in Rational Quality Manager. Because all Solution Manager keywords are mapped to the Rational Quality Manager SAP keyword table of the content object, this error does not likely cause visible problems. However, the occurrence of multiple sets of mappings suggests database corruption. Contact IBM Software Support.
