hi,

How to extend bapi_po_change useing extensionin and extensionout.

[che_eky]

Take a look at the documentation for the BAPI it gives good information:

The following user exits (function modules) are available for the BAPI BAPI BAPI_PO_CHANGE:

EXIT_SAPL2012_002 (at start of BAPI)

EXIT_SAPL2012_004 (at end of BAPI)

These exits belong to the enhancement SAPL2012 (see also transaction codes SMOD and CMOD).

There is also the option of populating customer-specific fields for header, item, or account assignment data via the parameter EXTENSIONIN.

when i execute the program, the debugger is not stooping at the above mentioned exit.

the below is the code.

data: lt_poaccount like bapimepoaccount occurs 0 with header line,

lt_poaccountx like bapimepoaccountx occurs 0 with header line,

return type bapiret2 occurs 0 with header line,

poitem like bapimepoitem occurs 0 with header line,

poitemx like bapimepoitem occurs 0 with header line,

extin like bapiparex occurs 0 with header line,

extou like bapiparex occurs 0 with header line.

poitem-po_item = '0010'.

poitemx-po_item = '0010'.

poitem-vendrbatch = 12322.

poitemx-vendrbatch = 'X'.

poitem-ematerial = 'TEST'.

poitemx-ematerial = 'X'.

poitem-grant_nbr = 'GRANT_NBR'.

poitemx-grant_nbr = 'X'.

poitem-no_more_gr = 'NO_MORE'.

poitemx-no_more_gr = 'X'.

append poitem.

append poitemx.

extin-structure = 'BAPI_TE_MEPOITEM'.

extin-valuepart1 = 'EAN_UPC'.

append extin.

lt_poaccount-po_item = '0010'.

lt_poaccountx-po_item = '0010'.

lt_poaccount-serial_no = '0001'.

lt_poaccountx-serial_no = '0001'.

lt_poaccount-gr_rcpt = '176'.

lt_poaccountx-gr_rcpt = 'X'.

append lt_poaccount.

append lt_poaccountx.

data: po_num type ebeln.

po_num = 7600000285.

call function 'BAPI_PO_CHANGE'

exporting

purchaseorder = po_num

tables

return = return

poitem = poitem

poitemx = poitemx

poaccount = lt_poaccount

poaccountx = lt_poaccountx

extensionin = extin

extensionout = extou

.

if sy-subrc eq 0.

call function 'BAPI_TRANSACTION_COMMIT'.

endif.

**

write 😕 'a'.

I believe the exists are for enjoy purchase orders. Have you created a project in CMOD for the exit and activated it????
