A task using the SAP Business One Connector Tool is failing at runtime and producing the following error in the event logs:
100000008 - License does not exist
This error relates to the SAP DI Server Module not being licensed and not the TaskCentre SAP B1 Connector Tool.
You can check if the DI Server has a valid license within SAP Business One under the following:
Administration -> License Administration -> Components tab
If the DI Server is licensed you will see an entry for DI-server (DIS). If not, you will need to carry out the appropriate action to re-establish a valid licence.
