Problem with updating pricing date using BAPI_SALESORDER_CHANGE

Question

Hi,
I need to update pricing date on sales order (but only on item level).
I have been trying to use  BAPI_SALESORDER_CHANGE but nothing changes.Bapi returns no errors, ends with success.
I hoped that bapi would change not only pricing date but also recalculate things the date affected.
Here is my code:
ls_head_inx-updateflag = 'U'.
ls_bapisdls-pricing = 'C'.
ls_item-itm_number = sales_order_posnr
ls_item-price_date = new_price_date
APPEND ls_item TO lt_item.
ls_item_inx-itm_number = sales_order_posnr
ls_item_inx-updateflag = 'U'.
ls_item_inx-price_date = 'X'.
APPEND ls_item_inx TO lt_item_inx.
CALL FUNCTION 'BAPI_SALESORDER_CHANGE'
          EXPORTING
            salesdocument     = sales_order
            order_header_inx = ls_head_inx
            logic_switch         = ls_bapisdls
          TABLES
            return                 = lt_return
            order_item_in     = lt_item
            order_item_inx   = lt_item_inx
Thanks & Regards,

Mario,
I run same code as yours and work for me fine, able to update ITEM pricing date.
I suppose you are using BAPI_TRANSACTION_COMMIT after your BAPI call, then only it will work.
Also note that VBKD table stores this date for header and item. In my system, there are generally only header rows in that table, but a new item row gets generated when I change the item date with the BAPI to some other date. Also, this BAPI sometimes issues a W message instead of ERROR for something like non-existing items, so carefully check your RETURN table too.
'Item 000002 does not exist' as WARNING message, so might be considering it as a success.
If nothing works, try to do the same thing for the same data using VA02 and check . If that works, BAPI will work surely.
