• It is not possible to change the VAT number for accounts via the SOAP API managecustomerin1.

• No error message is associated with this issue.

SAP Business ByDesign

1. Attempt to update the VAT number for a customer using the SOAP API managecustomerin1.
2. Observe that despite receiving a positive response from the API, the VAT number of the account does not change in the UI.

The issue may be due to the absence of a tax number action code in the SOAP request or due to an incorrect payload format.

Use below example payload for country France and ensure that the correct account ID and tax ID is used: 

<n0:CustomerBundleMaintainRequest_sync_V1 xmlns:n0="http://sap.com/xi/SAPGlobal20/Global">
<BasicMessageHeader/>
 <Customer actionCode="04">
  <InternalID>ABC</InternalID>
  <TaxNumber actionCode="04">
   <CountryCode>FR</CountryCode>
   <TaxIdentificationNumberTypeCode listID="FR">1</TaxIdentificationNumberTypeCode>
   <PartyTaxID>FR168XXXXXXXX</PartyTaxID>
  </TaxNumber>
 </Customer>
</n0:CustomerBundleMaintainRequest_sync_V1>

(ABC represents the Internal ID of an account, FR represents a Country Code and FR168XXXXXXXX represents a Party Tax ID)
