All counterparties have two options for submitting credit claims and debtor data: the online procedure and the file-transfer procedure. There is also a backup procedure for both types of submission

Online procedure

The online procedure can be carried out via the Deutsche Bundesbank’s ExtraNet and requires a MACCs login. Counterparties can submit credit claims and retrieve reports in the MACCs application. A distinction is generally made between the submission of debtor data and credit claims data. The system only allows the submission of debtor data in MACCs for first-time entries for debtors, which is why changes to debtor data, such as changes in the address or a change of legal form, must be sent by email to the support team credit claims immediately after they become known. 

The business types when submitting credit claims are subdivided into new submission, update and voluntary return. In order to minimise the frequency of errors, the principle of dual control is generally applicable for entries in MACCs. The evaluation functions provide counterparties with extensive information on current and historical submissions and stocks of credit claims (for information on the use of historical data from KEV, see the relevant section entitled “Current issues and circulars”). In addition, counterparties can access written confirmations, the evaluation list and the debtor search function under the “Evaluations” menu item. 

More information on the online procedure can be found in the MACCs documentation.

File transfer procedure

Like the online procedure, the file transfer procedure takes place via the Deutsche Bundesbank’s ExtraNet. The procedure for the submission (upload) and receipt (download) of files is described in detail in the MACCs documentation. 

The file transfer procedure is particularly useful for submitters who wish to assign a large number of credit claims to the Deutsche Bundesbank. The procedure for transferring a large number of data records for submissions, updates and returns of credit claims in a single file is largely automated, but requires the submitter to have appropriately programmed implementation routines in place in order to create the files to be transferred to the Deutsche Bundesbank and to ensure that the receipt and stock files received by the Deutsche Bundesbank are readable. 

Counterparties need to apply for the file transfer procedure separately. For this purpose, Deutsche Bundesbank provides templates for the structure and content of the files. The templates are described in detail in the “Explanatory notes on the files in the MACCs file transfer procedure”, including a comprehensive description of the plausibility checks implemented for the submission file.

Please contact the support team credit claims if you would like to receive the current version of the "Explanatory notes on files in the MACCs file transfer procedure" by e-mail. You will find our e-mail contact on the right.

Backup procedure

When MACCs was designed, great importance was attached to high availability. In the event that access to MACCs is not possible during operating hours, the backup procedure is generally employed after consultation with the support team credit claims. This allows for the submission, updating and return of credit claims as well as the updating of ratings via email. More information on the backup procedure can be found in the MACCs documentation. Should you experience any problems or disruptions in relation to MACCs or accessing ExtraNet, you are advised to contact the support team credit claims immediately. The operating and support hours can be found at the top right-hand side of this page.
