ABAP Lesser Known Heroes Series – Value Operator : Part 2
This is a continuation of my post series,
Value operator is a relatively new addition to the ABAP language and the developers already have started extensively using this feature. But here I am writing about one of its functionality which is not widely noticed .
More about value operator from ABAP documentation,
Value operator is particularly helpful in feeding internal table with values .
REPORT ZSAMPLE_VALUE. TYPES: gtt_sflight TYPE STANDARD TABLE OF SFLIGHT WITH DEFAULT KEY . DATA(lt_flights) = VALUE gtt_sflight( ( carrid = 'AA' connid = '0017' fldate = '26.11.2020' price = '422,94' ) ( carrid = 'AZ' connid = '0018' fldate = '29.12.2020' price = '100.89' ) ( carrid = 'DL' connid = '0019' fldate = '30.05.2021' price = '422,94' ) ).
And here is the utility of ‘value’ operator which I accidently found out while using ‘where used’ list of a BAPI.
CALL FUNCTION 'BAPI_MATERIAL_SAVEDATA' EXPORTING headdata = VALUE bapimathead( material_long = rv_matnr ind_sector = 'M' matl_type = 'FERT' basic_view = 'X' storage_view = 'X' account_view = 'X' purchase_view = 'X' ) clientdata = VALUE bapi_mara( matl_group = get_material_group( ) base_uom = get_unconverted_uom( ) net_weight = '10' unit_of_wt = 'KG' ) clientdatax = VALUE bapi_marax( matl_group = 'X' base_uom = 'X' net_weight = 'X' unit_of_wt = 'X' ) plantdata = VALUE bapi_marc( plant = get_plant( ) pur_group = get_purch_group( ) ) plantdatax = VALUE bapi_marcx( plant = get_plant( ) pur_group = 'X' ) valuationdata = VALUE bapi_mbew( val_area = get_valuation_area( ) price_ctrl = lv_price_ctrl std_price = '10.00' price_unit = lv_price_unit moving_pr = '10.00' val_class = get_valuation_class( iv_matl_type = 'FERT' ) ) "3300/7920 depends on system valuationdatax = VALUE bapi_mbewx( val_area = get_valuation_area( ) price_ctrl = 'X' std_price = 'X' moving_pr = 'X' price_unit = 'X' val_class = 'X' ) storagelocationdata = VALUE bapi_mard( plant = get_plant( ) stge_loc = get_storage_location( ) ) storagelocationdatax = VALUE bapi_mardx( plant = get_plant( ) stge_loc = get_storage_location( ) ) TABLES materialdescription = lt_create_material_matdscr returnmessages = lt_returnmessages.
Code from CL_API_RESERVATION_DOC_DPC_EXT – Local Test Class
We no more have to declare the input structures for a FM/BAPI separately . We could use the value statement with the corresponding structure and feed with the values for the parameters. This feature is useful particularly when used in test classes. The icing on the cake is, we could even assign a functional method to the parameter list. Easy huh ??
Footnote: But one strange thing which I noticed is that , we can only feed structures with a value to the function modules/BAPI’s but not internal tables. I wonder why. May be the list gets longer? But could have been good enough for testing classes with one or two line items?
TABLES materialdescription = value t_bapi_makt( ( langu = 'D' langu_iso = 'DE' matl_desc = 'Sample Material' del_flag = ' ' ) ) returnmessages = value cfx_bi_tt_bapi_matreturn2( ( type = 'E' ID = 'SD' number = '120' message = 'Sample' ) ).
The above code throws error when used with BAPI ‘BAPI_MATERIAL_SAVEDATA’ .
May be Horst Keller can show some light on this ?
