Problem in select_options in AMDP

Hello Expert,

I am using select_options in SAP AMDP. But it is showing the below error:

CLASS ZCL_HANA_AMDP DEFINITION

PUBLIC

FINAL

CREATE PUBLIC .

PUBLIC SECTION.

INTERFACES:if_amdp_marker_hdb,

IF_SHDB_DEF.

TYPES: ty_where_t type TABLE OF IF_SHDB_DEF=>TT_NAMED_DREF.

CLASS-METHODS: select_options importing value(iv_where_cond) type ty_where_t

exporting value(et_sflight) type tt_sflight.

PROTECTED SECTION.

PRIVATE SECTION.

DATA : itab TYPE TABLE OF sflight.

ENDCLASS.

Error Details:

The method "SELECT_OPTIONS" contains a database procedure, which means that the row type of "IV_WHERE_COND" must be structured. All components of the row type must be elementary.

Please help me to fix this problem.

Thank you.

Best Regards,
