Discussed with Arvin the issue of POS2NAV of SSI. The Sales Audit is trying to upload on NAV  but whenever they tried uploading, there is an error "The table is locked or being use by another user." I tried restarting the database server and the application server so that all the sessions will be removed but the same issue is occurring. Seek help from Arvin to check on the SQL all the sessions and upload on the POS Payment table to see all the sessions there, if possible. The query is still executing and I advised the sales Audit team that we will try to restart again the server after office to see if they can now proceed with the uploading since all of the user will be logged out on NAV by that time. We are already done restarting the server and I already advised the user to try uploading again using the POS2NAV. Waiting for the feedback from the user if the successfully upload using POS2NAV.
