MPOS not going offline - On Premises

(0) ShareShare
ReportReport
Posted on by Usama Bin Mazhar 66

Dear Community, 

Client is using On-Premises environment. The MPOS is not going offline even though all configurations are OK. The offline DB is installed with the POS and the installation was successful. 

We have customizations on MPOS which is why we're using a custom installer for the MPOS. When trying to manually swicth from online to offline, the event viewer gives the following error.

The MPOS generates the following error

Event Log

ChannelRequestFactory Switching connection state to offline failed, Offline not available (83e4b078-35df-fbfb-cea2-d9c62f3537c0). Correlation Id: 'f321b65b-f6d2-c273-3c31-81601674e219'

Another thing I've noticed is that there is no Offline Sync Service in my services.msc

Any help shall be highly appreciated please.

BR.

    Please have a look into Event Viewer for MPOS logs, analyze Warnings/Errors and preceding informational messages and you should be able to find the root cause. Depending on the version you are using the logs could be under Microsoft-Dynamics-Commerce-ModernPOS or under Windows Logs-Application

    if you are using cusotmized POS make sure all the custom entities have the Key attribute applied on them.

    Please follow the link already shared by a community member to make sure that, data has been fully synched. If the issue persists, I would recommend to first isolate the issue by checking, if the offline is working when you use the installer from MS. This step will help you diagnose if there is any issue with the customized installer. I have seen sometimes that, the download fail as the who is running the MPOS application doesn't have access on the MS SQL. To check this, take any table like ax. Currency and see if the data exist in the table.

    Unlike self hosted store scale unit and offline POS in AX, you will not see any service in windows services. The framework for uploading and downloading the data is embedded within MPOS itself. That is, upload and download will work only when the MPOS application is open.

    Hi Usama Bin Mazhar,

    Please make sure all the jobs are applied for offline and sync with offline database.

    Offline point of sale (POS) functionality - Commerce | Dynamics 365 | Microsoft Docs

    As per above document, click sync and verify the status of all jobs "OK".

    Best Regards,

    Charlotte
