If you open a dataport object in Dataport Designer, the dataport closes when you close the Dataport Designer window.
If you enter ID and Name as dataport properties, these values will be used, and you will not be prompted for ID and Name when you close the dataport.
You can save a dataport without closing it, and you can use the steps for saving a dataport to make a copy of an existing dataport.
To save a dataport
Click File, and then click Save.
In the Save As dialog box, in the ID field, enter a number that will serve as a unique identification for the dataport.
There are restrictions about which numbers you can use. Contact your Microsoft Certified Partner for information.
In the Name field, type a descriptive name for the dataport.
Optionally, if you want to save the dataport without compiling it, in the Compiled field, remove the check mark.
