Customs Management Interface
To view error information via the Customs Management interface, see the example steps below.
Identify the data element path
Firstly, identify the data element path to search for further information. To do this:
- Select the Customs information tab and go to the Customs messages section.
- Locate the latest error message and click on it. In the example below, the error has been received from CDS, so the error message type will be DMSREJ. The list of related errors will then be shown in the grid underneath.
- Select the error you wish to investigate and click Open.
- This will then display the full error details. Make a note of the data element path shown.
Viewing the MetaData
- Select the declaration message that was sent to Customs, which caused the error to be returned. In the example below, the DMSDEC is the declaration message that was sent to CDS just prior to the DMSREJ error message being received.
- Highlight the correct message, and click Open.
- Select the Message content tab and expand the MetaData heading.
- Expand the links to follow the data element path noted in the error message. (In this example:)
- Expand the links in sequence (i.e. Declaration > AuthorisationHolder > CategoryCode).
- This gives an indication of which declaration data has caused the error. For example, it may be that:
- The error relates to this exact element of data e.g. the Category code of EXRR is incorrect.
- There may be something incorrect at a higher level.
- A combination of different values entered is not allowed.
- Other data in the declaration is causing Customs to generate an error for this data.
If you require further assistance with errors received from Customs, you can contact the relevant Customs Helpdesk. See How to contact Customs Helpdesks.
If Customs request that the related customs messages are sent to them, see How to Download Customs Messages to Send to a Customs Authority.
CDS Specific
See HMRC webpages for further information:
HMRC provide a document on how to understand CDS error messages (DMSREJ). The document is called Understanding DMSREJ - A How To Guide, which is available in the Customs Declaration section of their technical documentation, available via this link.
This document advises on how to read the various sections of an error message, shown in XML format. To view the error message in XML format, follow the instructions to Download Customs Messages.
