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.
VBAP: In your append structure you specify your ZZFIELD with the data type as needed
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
?BAPE_VBAPX: In the append structure add the field ZZFIELD of type BAPIUPDATE
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
?VBAPKOZX: 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)
(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 definitionsDATA: 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.

ENDLOOP.
* Then the call to the BAPICALL FUNCTION 'BAPI_SALESORDER_CREATEFROMDAT2'EXPORTINGorder_header_in??= ls_order_header_inorder_header_inx = ls_order_header_inxIMPORTINGsalesdocument? ? = lv_salesdocumentTABLESreturn? ?? ?? ???= lt_ret2order_items_in? ?= lt_order_items_inorder_items_inx??= lt_order_items_inxorder_partners? ?= lt_order_partnersorder_keys? ?? ? = lt_order_keysextensionin? ?? ?= 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.
