We cannot advise with limited information. Please provide the context and purpose here. Some information we need to know: What is the table you want to copy data from? What is the table you want to copy data to and why? Usually, with a good structure, there is simply no need to copy data from one place to another; you would instead relate the data-sets and refer to them through the relationship.
Thank you for your post.
Besides the reply from LaRetta being correct (Thank you!), it sounds like you are copying and pasting via a script. Instead, you may want to use "Set Variable" script step. Here is a simple example of taking four fields (Name, Address, City, and State) and transferring the information to another layout.
Go to Layout [ <layout where initial table is located> ]
Set Variable [ $name ; <initial table>::Name ]
Set Variable [ $add ; <initial table>::Address ]
Set Variable [ $city; <initial table>::City ]
Set Variable [ $st ; <initial table>::State ]
Go to Layout [ <layout where second table is located> ]
Set Field [ <second table>::Name ; $name ]
Set Field [ <second table>::Address ; $add ]
Set Field [ <second table>::City ; $city ]
Set Field [ <second table>::State ; $st ]
This will help you from switching back and forth between layouts and copying and pasting one field at a time.
Please let me know if you need clarification for any of the above steps.
