Hello FI Gurus,
We have a current business process in place to post Invoices for utility bills. Utility companies will send out a paper copy of Vendor invoice to customer AP team. They will also send a Reconciliation file with all the invoices/amounts but at a later point.
Now when Customer AP team receives the paper invoice, they key in the information into FB60 to specific GL accounts.
First GL Account: For non-taxable GL account with net invoice amount
Second GL: TAX only GL account to key in Tax amount.
When they try to post this invoice, FB60 gives enables a button called "Tax Base" for the Tax GL account line. User can press this
button, enter the Tax base amount in the pop-up sceen and post the invoices.
We are trying to automate this process by using workflow and posting the same document via BAPI_ACC_DOCUMENT_POST. However, not successfull
as we are not able to pass the tax base anount via BAPI for the Tax GL line item which SAP is expecting to post the invoice.
My attached document also has an example of the GL accounts and FB60 screenshots for your quick reference.
