If you are going to use function 12, Retrieve part information, you need to install a scheduled job. Start SQL Server Management Studio and open the script 'Create_job_populating_MT_PartInvtInfo.sql' that was installed in the folder specified by the Isah Mobile Script Installer. The script creates a scheduled job that fills the MT_PartInvtInfo table at the time specified. Change the time and interval if required and run the script to create the scheduled job.
Then execute the stored procedure MIP_BATCH_MT_PartInvtInfo once to fill the table:
Exec MIP_BATCH_MT_PartInvtInfo
This may take a few minutes.
