Journal Voucher Posting Error in Postman – Invalid TaxGroup Value

[UrvishPatel]

Hi Ankit,

Good afternoon.

I’m trying to post a journal voucher using Postman, but I keep receiving an error. Below is the JSON payload I used and the error message I received.

JSON Payload:

{
"ReferenceDate": "2025-04-14",
"DueDate": "2025-04-14",
"TaxDate": "2025-04-14",
"Memo": "JE - Subsidy & Travel",
"JournalEntryLines": [
{
"AccountCode": "607403",
"Debit": 100.00,
"Credit": 0,
"LineMemo": "Subsidy UK",
"TaxGroup": "I1"
},
{
"AccountCode": "607400",
"Debit": 200.00,
"Credit": 0,
"LineMemo": "Travelling UK",
"TaxGroup": "I1"
},
{
"AccountCode": "115418",
"Debit": 360,
"Credit": 360,
"LineMemo": "LuLu"
}
]
}

Error Message:

{
"error": {
"code": -5002,
"message": {
"lang": "en-us",
"value": "10000415 - Linked value I1 does not exist"
}
}
}

It looks like the error might be related to the TaxGroup value "I1". Could you please check if this value is valid or help me understand what's going wrong?

Thanks for your support.

Best regards,

Urvish

Hi @UrvishPatel ,

SAP B1 UK localisation uses VatGroup rather than TaxGroup as the tax identifier at the line level.

Give it a try and let us know.
