The problem of Ms. Jessica reoccurs again. I advised her to try restarting her PC, but the same problem still persists. I checked if the other companies also have no data but upon checking on GAP the data is there. I tried restarting all the services of NAV 2009 then tried logging in on GSRI again. I also checked the NAV on the application server if the same problem occurs with the client PC, the same problem occurs on the App Server. I checked on the database of GSRI-LIVE, select the table of the purchases invoice then tried running the top 1000 rows at first, then tried selecting all the data on the purchases invoice of GSRI. All the data were there but it can't be sync on the NAV. I already seek advised from the vendor PASI and waiting for their advised.
