SAP DBTech JDBC: [2048]: column store error: search table error: [6906] Attribute engine index not found

hi，experts

      I just execute a simple SQL in our hana platform(hana 102.2). such as:

      select a.* ,b.org_id from sale_order a inner join customer_info b on a.customer_id=b.customer_id

      The quantities of the two table'record is not big,about 600,000.  But it met a error:

      SAP DBTech JDBC:[2048]: column store error: search table error:[6096] Attribute engine index not found.

      after I reload the data of the two tables, the SQL could be executed.I am worried about the error will come again and want to find the reasons.
