Hi,
You can use the badi "BBP_DETERMINE_LOGSYS".
Read the documentation below:
BADI - BBP_DETERMINE_LOGSYS
code
You can use the Business Add-In BBP_DETERMINE_LOGSYS to define your own criteria for determining the backend system / company code. You use this BAdI to determine the source system for
Shopping cart items
In the standard system, the backend system is determined using the product category Define Backend Systems. The backend System is placed in the field ITEM_DATA-LOGICAL_SYSTEM. Then the system calls the Business Add-In BBP_DETERMINE_LOGSYS.
The company code is put in the field ITEM_DATA-BC_CO_CODE. Then the system calls the Business Add-In BBP_DETERMINE_LOGSYS.
Contracts
In the standard system, the system creates contracts locally from Sourcing and SAP Bidding Engine You can use this BAdI to determine a backend system.
Example
Shopping Cart:
Backend system A is determined for product category OFFICEMATERIAL. You also want to consider the vendor and purchasing organization fields during determination of the backend system. The purchase order is to be created in backend system B for the vendor OFFICE1 and purchasing organization 0001. You overwrite the field ITEM_DATA-LOGICAL_SYSTEM with B.
Contract:
The local system used by the standard system to create contracts is XYZ4711. In the field CV_LOGSYS, you enter the logical system ABC0815 that links to a backend system. In this way, contracts are created in the backend system.
Standard settings
The BAdI provides the following methods:
-> DETERMINE_LOGSYS
-> CONTRACT_LOGSYS_DETERMINE
Activities
Implement this BAdI if you want to define a target system that is different from the standard system.[/code]
Sample code for BBP_DETERMINE_LOGSYS BADI
codemethod IF_EX_BBP_DETERMINE_LOGSYS~DETERMINE_LOGSYS.
data: w_acct_data type enriched_acct_data.
data: w_acct_icom type BBP_PDS_ACC_ICOM.
data: w_et_messages type BBP_TMESSAGES_BADI.
data: re_obj(40).
data: imkey(8).
field-symbols: <waItem> type bbp_oci_enritem.
field-symbols: <waAcct> type bbp_oci_enracct.
field-symbols: <f1> type any.
if not acct_data[] is initial.
loop at item_data assigning <waItem>.
loop at acct_data assigning <waAcct> where line = <waitem>-line.
check <waAcct>-acc_cat = 'RE'.
if not <waAcct>-acc_str is initial.
CALL FUNCTION 'Z_RE_ACCT_ASSGN'
EXPORTING
ACC_STR = <waAcct>-ACC_STR
BUKRS = <waItem>-BE_CO_CODE
IMPORTING
RE_OBJ = RE_OBJ
IMKEY = IMKEY
TABLES
BBP_RETURN = w_et_messages.
endif.
if not imkey is initial and w_et_messages[] is initial.
move imkey to <waAcct>-rl_esk_key.
move re_obj to <waAcct>-acc_str.
modify acct_data from <waAcct>.
endif.
endloop.
endloop.
endif.
endmethod.[/code]
