I am configuring VAT input tax for country thailand in ECC 6.0 release.
The official VAT input number is generated correctly on document header text.
But the number is always skip by 1 number when i do a posting via FI (eg vendor invoice, document type KR)
firt document posted is with tax number 90000, then when i post another document, the number was jumped to 90002
Kindly your input on this issue.
