CE view error for date field

Hi

I am trying to add 2 date fields and it throws me an error. Any suggestions would be appreciated.

Could not execute 'SELECT Table__1."RECEIVED_DT", Table__1."SNAPSHOT_DATE" FROM ...' in 1.605 seconds .

SAP DBTech JDBC: [2048]: column store error: search table error:  [2620] executor: plan operation failed;ceUnionPop (Union_1): Failed to append column RECEIVED_DT; current column type = AppendedColumn<daydate>(NullColumn<daydate>, NullColumn<daydate>, NullColumn<daydate>) other column type =CompactResultColumn<date>

I am using SAP HANA Version: 1.00.81.0

Cheers!
