Open Record/Request
Makes an existing record or find request available for editing.
Open Record/Request
This script step is also supported in web publishing and in a FileMaker Server scheduled script.
Originated in 
FileMaker Pro 6.0 or earlier
When performed on a record, this script step verifies that the user has sufficient access privileges to edit the record. If the user has the proper privilege set, FileMaker Pro attempts to prevent others from simultaneously editing or deleting the record. Once locked, the record is considered “opened” and may be edited.
If an error occurs (for example, if the current user has insufficient access privileges, the record is currently locked by another user, or the record is open in another window), FileMaker Pro generates an error message, which may be captured using the Set Error Capture script step and the Get(LastError) function. (Opening a find request will not return an error, because requests can’t be locked by other users.)
Important  Because any attempt to modify a field or a record will also attempt to open the record for editing, in most cases you will not need to use the Open Record/Request script step to open a record explicitly. But when using the Go to Record/Request/Page script step to enter a field or record, use the Open Record/Request script step first to obtain a write lock.
