importing
salesdocument = gv_vbeln
tables
return = gt_return
order_items_in = gt_items
order_partners = gt_partners
order_schedules_in = gt_schedules
order_conditions_in = gt_conditions.
when others.
call function 'BAPI_SALESDOCU_CREATEFROMDATA1'
exporting
sales_header_in = gs_order_hd1
importing
salesdocument_ex = gv_vbeln
tables
return = gt_return
sales_items_in = gt_item1
sales_partners = gt_part1
sales_schedules_in = gt_sch1
sales_conditions_in = gt_cond1.
endcase.

Answer 1

If you want to change a value, you need to pass the value in the 'order_items_in = gt_items' structure.
You also need to add an 'X' in the 'order_items_inx = gt_itemsx'  structure for the same field.
If you do not pass the 'X' then the value will not be updated...
It looks like you are not passing the required '...x' structures.

                    SALES_ORG    Sales organization                       
                    DISTR_CHAN   Distribution channel                     
                    DIVISION     Division

2.  Ship-to party:                                                                               
If no ship-to party is entered, use the following: Ship-to party =

3.  Commit control:                                                     
      The BAPI does not have a database commit. This means that the       
      relevant application must leave the commit, in order that can be    
      carried out on on the database. The BAPI BAPI_TRANSACTION_COMMIT is 
      available for this.                                                                               
4.  German key words:                                                   
      The following key words must be entered in German, independantly of 
      the logon language:                                                 
      DOC_TYPE     Sales document type, for example: TA for standard order
      PARTN_ROLE   Partner role, for example: WE for ship-to party
