Open Record/Request
Makes an existing record or find request available for editing if the current user has record-editing privileges.

Where the script step runs 
FileMaker Pro 
FileMaker Server scheduled script 
FileMaker Go 
Custom Web Publishing 
FileMaker WebDirect 
Runtime solution 
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.
Example 1 
Prints the current invoice if the user has the privileges to edit it.
Go to Layout ["Print Invoices"]
Open Record/Request
If [Get ( LastError ) = 0]
Print [ ]
End If
Go to Layout [original layout]
Example 2 
Checks if the current user account has the privilege to edit records. If not, asks if the user wants to log in to a different account.
Note  This script does not run properly if Run script with full access privileges is selected because this option allows any account to open the record.
Set Error Capture [On]
Go to Layout ["Invoice Details"]
Open Record/Request
If [Get ( LastError ) = 200]
Show Custom Dialog ["You cannot edit this record. Do you want to re-login?"]
If [Get ( LastMessageChoice ) = 1]
Re-Login [ ]
Go to Layout [original layout]
End If
End If
