Advanced users may use the class /DVD/OFF_CL_DATAPROV_QUERY to create their own reports to retrieve data. Below you can find API documentation of the SELECT method of this class.

CALL METHOD /dvd/off_cl_dataprov_query=>select EXPORTING iv_dataprov = lv_datapov_name it_fields = it_fields iv_where = `CALYEAR BETWEEN '1991' AND '2016' AND /DV1/S_DMTEMP = '1529.000'` CHANGING ct_data = ct_data.

Parameters of above SELECT method:

How to obtain fields of a DDIC table

Use the Function Module DDIF_FIELDINFO_GET to obtain fields of DDIC table, which are used as an importing parameter for the table it_fields.

CALL FUNCTION 'DDIF_FIELDINFO_GET' EXPORTING TABNAME = lv_ddic_tabname * FIELDNAME = ' ' * LANGU = SY-LANGU * LFIELDNAME = ' ' * ALL_TYPES = ' ' * GROUP_NAMES = ' ' * UCLEN = * DO_NOT_WRITE = ' ' * IMPORTING * X030L_WA = * DDOBJTYPE = * DFIES_WA = * LINES_DESCR = * TABLES * DFIES_TAB = * FIXED_VALUES = * EXCEPTIONS * NOT_FOUND = 1 * INTERNAL_ERROR = 2 * OTHERS = 3 .
