Debugging FLink transactions

Debugging through middleware

Included as of version: 1.6.4

In order to facilitate error analysis in connection with FLink systems, each command that RetailForce Fiscal Middleware transmits to FLink is stored in a file ring buffer. The last 15 requests are then stored in the "flink" directory of the client data directory (C:\ProgramData\RetailForce\Fiscal Webservice\<client guid>) for possible later analysis.

If the command contains a document, the DocumentGuid is included in the file name for easier referencing.

Debugging printer communication

In some cases, it is necessary to be able to read out the communication between FLink and the fiscal printer used.

To activate this, the file

• FiscComm.log

must be created in the directory C:\temp>.

If a document is now sent to the middleware, a .txt document is also created with the corresponding date and time specified in the file name (e.g. 231116141040.txt).

Please note that the content of the FiscComm.log file is deleted each time FLink is restarted.

Regular log data can be found in:

• FLink.LOG and
• FLink$.LOG
