I would like to provide additional information in case of SAP notes are not applied as follows.
• Master data: It is no branch code information in Customer and Vendor master data. It will impact input tax and output tax transaction.
• Transaction: User has to enter branch code manually in
o Input tax process (Invoice verification, Vendor manual invoice)
o Transfer Deferred Input tax to Input tax
o Output tax process (Sales order creation, Miscellaneous Invoicing)
• Form: Customize form to show Branch code in SD Tax Invoice, FI Miscellaneous Invoicing, Credit note, Debit note etc.
• Report: Need to develop Input Tax report and Output Tax report to get data that maintain in each transaction.
I attached Solution detail of Thailand SD, MM and FI Extensions for Capturing Branch code document for more understanding.
Please give me your feedback that I can process the next step.
