There are some database records that may only be open for update by one person at a time. A good example is a Work Order. Only one Service Advisor may have a Work Order open for updating at a time. So when a Service Advisor opens a Work Order, the software places a lock on that record on the database server. If a second Service Advisor attempts to open that Work Order, he can't - it's locked. Work Orders are unlocked when the Service Advisor closes the Work Order.
The software places this type of multi-user lock on only three types of records:
Work Orders,
Accounts Receivable, and
Accounts Payable.
If a workstation is turned off or encounters an error while a record is locked, that record would remain locked. In this unusual situation, someone at the business Location would need to unlock the records. This is done by:
Selecting Tools | Remove All Locks
Answer OK to the confirmation dialog.
TECHNICAL INFO: When a workstation is inadvertently turned off or the software encounters a severe error while a Work Order, A/R account or A/P is locked open, the changes to the record made since the last save are lost. However no damage has been done to your database. After the lock is removed and the record is retrieved, simply re-do the changes to the record and save it.
Your data is entirely safe.
