报错:indexName name is too long. max length is 18, at line 1, column 15

[{"operation":"SL_KFHT.MBIClick.tbButton_XC"}]
发生时间：15:32:23
错误来源： Kingdee.BOS.SQL
错误信息：indexName name is too long. max length is 18, at line 1, column 15
===================================================
调用堆栈：
at Kingdee.BOS.SQL.Parser.SqlStmtParser.parseCreateIndex(String createWord)
at Kingdee.BOS.SQL.Parser.SqlStmtParser.stmt()
at Kingdee.BOS.SQL.Parser.SqlStmtParser.stmtList(IList stmtCol, Token tok)
at Kingdee.BOS.SQL.TransUtil.getStmtList(String ksql)
错误数据： System.Collections.ListDictionaryInternal

BOS 单据 下查 关联查询时候 都报这个错 重启客户端 清理了缓存 还是没有用
请问怎么解决???
