BAPI_POSRVAPS_CREATESNPORDER to change existing order

Hi Experts,

I am using the following code to change the Deployment results - Confirmed Stock Transfer Requisition (EG and EF).

After SNP heuristics run, the standard SAP deployment run happens. Then, a stock transport order with reference to production order is created without reference to stock transport requisition or confirmed stock transfer requisition. So, to consume or reduce this confirmed STR quantity, I am using the following code. But the issue is, the date of the confirmed stock transfer requisition gets changed after this BAPI FM. I don't want the date to be changed. Does anyone have any idea of how to just change the quantity, but not to change the dates?

CALL FUNCTION 'BAPI_POSRVAPS_CREATESNPORDER'

EXPORTING

logical_system         = 'SAPXXX113'    " My current SAP APO system

APPLICATION            = 'DEP'        " Changing Deployment orders

EXT_NUMBER_ASSIGNMENT  = ' '        " I use ORDERID, instead of the order

order_data             = lt_order_data    " Data to be updated

return                 = lt_return.    " Return message of BAPI update

For filling the internal table lt_order_data, I am using the function module BAPI_POSRVAPS_GETLIST3.

ls_order_data-unitofmeas    = ls_requirements-unitofmeas.

ls_order_data-unitofmeas_iso = ls_requirements-unitofmeas.

ls_order_data-order_start_date = ls_requirements-requirement_date. "What date to use here? Whatever the date I give it changes the already existing date. I don't want the dates to be changed

ls_order_data-order_end_date   = ls_requirements-requirement_date.

ls_order_data-fixed             = ls_requirements-fixed.

clear: ls_order_data-atpcat_from, ls_order_data-atpcat_to, ls_order_data-trans_priority.

Thanks,
