When i query with kylin,it reminds me: Not a valid value

[周湘伦]

Hi,all
When i query with kylin,some error occured:
10:45:41.302 [Query e147b8bb-ec9d-48c1-bde8-904c764468f2-200] ERROR
org.apache.kylin.dict.TrieDictionary - Not a valid value: 20170918

Define as follows：

ID Column Encoding Length Shard By

2 TBL_BILL_GENERAL.SETT_DATE dict[v1] 0 false

DataSource define:
SETT_DATE char(8)

This error can also occur if the corresponding fields in the table do not
have this data,then i deleted those values that are not present in the
table.

However, there are still errors in the correct field that has data such as
sett_date.

How can i solve the problem?
Best regards.
