在表VBAP和VBAK上增加新字段的標準BAPI?
If you have custom ZZ fields on VBAP and VBAK then you can update these fields using the standard BAPI to create or change the order and update these fields.
A lot has been spoken about this but nowhere does it spell out the pitfalls and give you an end-to-end procedure on how to do it. I even found some "SAP Experts - Ask a question" on Search SAP give a complete wrong answer!!! So here is the correct way to do it.
--------------------------------------------------------------------------------
To do so you first need to ensure that the following 5 tables are in synch.
1) VBAP: In your append structure you specify your ZZFIELD with the data type as needed
2)?BAPE_VBAP: In the append structure here also add the ZZFIELD with the data type as needed with limitations. No decimals. Try and stick to char characters
3)?BAPE_VBAPX: In the append structure add the field ZZFIELD of type BAPIUPDATE
(NOTE: (2) and (3) must have the same number of fields in the same order)
4) VBAPKOZ: In the append structure here also add the ZZFIELD with the data type as needed with limitations. No decimals. Try and stick to char characters
5) VBAPKOZX: In the append structure add the field ZZFIELD of type BAPIUPDATE
(NOTE: (4) and (5) must have the same number of fields in the same order)
Similarly do for VBAK,?BAPE_VBAK,?BAPE_VBAKX, VBAKKOZ and VBAKKOZX.
Next we get to the code to fill in the structure EXTENSIONIN
I will demonstrate how to call the create sales order BAPI with custom fields.
* Local definitions
??DATA: wa_extensionin TYPE bapiparex,
? ?? ???wa_bape_vbap? ?TYPE?bape_vbap,
? ?? ???wa_bape_vbapx??TYPE?bape_vbapx,
? ?? ???wa_bape_vbak? ?TYPE?bape_vbak,
? ?? ???wa_bape_vbakx??TYPE?bape_vbakx,
? ?? ???lv_posnr? ?? ? TYPE posnr.
* Processing the header extension
??CLEAR wa_bape_vbak.
??wa_bape_vbak-ZZFIELD? ???= 'HDRTEST'.
??wa_extensionin-structure = 'BAPE_VBAK'.
??wa_extensionin+30(960)? ?= wa_bape_vbak.
??append wa_extensionin to lt_extensionin.
??clear wa_extensionin.
* Processing the line extension
LOOP AT line_items INTO wa_lineitems.
??ADD 10 TO lv_posnr.? ?
??CLEAR wa_bape_vbap.
??wa_bape_vbap-ZZFIELD? ???= 'TEST'.
??wa_extensionin-structure = 'BAPE_VBAP'.
??wa_bape_vbap-posnr? ?? ? = lv_posnr.
??wa_extensionin+30(960)? ?= wa_bape_vbap.
??append wa_extensionin to lt_extensionin.
??clear wa_extensionin.
??CLEAR wa_bape_vbapx.
??wa_bape_vbapx-ZZFIELD? ? = 'X'.
??wa_extensionin-structure = 'BAPE_VBAPX'.
??wa_bape_vbapx-posnr? ?? ?= lv_posnr.
??wa_extensionin+30(960)? ?= wa_bape_vbapx.
??append wa_extensionin to lt_extensionin.
??clear wa_extensionin.
ENDLOOP.
* Then the call to the BAPI
? ?? ?CALL FUNCTION 'BAPI_SALESORDER_CREATEFROMDAT2'
? ?? ???EXPORTING
? ?? ?? ? order_header_in??= ls_order_header_in
? ?? ?? ? order_header_inx = ls_order_header_inx
? ?? ???IMPORTING
? ?? ?? ? salesdocument? ? = lv_salesdocument
? ?? ???TABLES
? ?? ?? ? return? ?? ?? ???= lt_ret2
? ?? ?? ? order_items_in? ?= lt_order_items_in
? ?? ?? ? order_items_inx??= lt_order_items_inx
? ?? ?? ? order_partners? ?= lt_order_partners
? ?? ?? ? order_keys? ?? ? = lt_order_keys
? ?? ?? ? extensionin? ?? ?= lt_extensionin.
Note: If you have a need to force a different Business Object type or wish to see the extension return fields then use the function SD_SALESDOCUMENT_CREATE instead.
? ?? ?CALL FUNCTION 'SD_SALESDOCUMENT_CREATE'
? ?? ???EXPORTING
? ?? ?? ? sales_header_in? ???= ls_order_header_in
? ?? ?? ? sales_header_inx? ? = ls_order_header_inx
? ?? ?? ? business_object? ???= 'BUS2032'
? ?? ???IMPORTING
? ?? ?? ? salesdocument_ex? ? = lv_salesdocument
? ?? ?? ? sales_header_out? ? = lv_sales_header_out
? ?? ?? ? sales_header_status = lv_sales_header_status
? ?? ???TABLES
? ?? ?? ? return? ?? ?? ?? ???= lt_ret2
? ?? ?? ? sales_items_in? ?? ?= lt_order_items_in
? ?? ?? ? sales_items_inx? ???= lt_order_items_inx
? ?? ?? ? sales_partners? ?? ?= lt_order_partners
? ?? ?? ? sales_keys? ?? ?? ? = lt_order_keys
? ?? ?? ? extensionin? ?? ?? ?= lt_extensionin
? ?? ?? ? incomplete_log? ?? ?= lt_incomplete_log
? ?? ?? ? extensionex? ?? ?? ?= lt_extensionex.
