This blog contains the step-by-step process to update the withholding tax of an accounting document using ‘BAPI_INCOMINGINVOICE_CREATE’.

We generally use to analyze a lot to update the data in withholding tax of any accounting document.

We can simply create/update the withholding tax data by simply passing 2 required parameters to the FM ‘BAPI_INCOMINGINVOICE_CREATE’.

The parameters are:

Parameter 1: HEADERDATA

Pass the supplier (LIFNR) of the PO to HEADERDATA-diff_inv

We can pass the PO number into EKKO table and get LIFNR

Parameter 2: WITHHOLDINGTAX

Pass the supplier of the PO to table LFBW and fetch WITHT and WT_WITHCD.

Pass these values to WITHTAXDATA.

WITHTAXDATA-SPLIT_KEY = ‘000001’

WITHTAXDATA-WI_TAX_TYPE = LFBW-WITHT

WITHTAXDATA-WI_TAX_CODE = LFBW-WT_WITHCD

Below code snippet can be used for our scenario:

CALL FUNCTION ‘BAPI_INCOMINGINVOICE_CREATE’2EXPORTING
headerdata = ls_header “PO Header dataIMPORTING
invoicedocnumber = lv_invno “Invoice posted
TABLES
itemdata = lt_item “PO Item data
withtaxdata = lt_whtax “with holding tax data
return = lt_return. “Return table for messages

After successful creation of invoice, the withholding tax data will be populated in withholding tax tab.
