Using Hold Data and Set Data 
You use functions Hold Data or Set Data when you want to create a group of objects that contain similar data. Both of these functions automatically enter the specified data in the specified field.
When you use Hold Data, you can change the held data when it appears in the input fields. When you use Set Data, the cursor skips input fields with held data and you cannot change it.
There is no limit to the number of screens you can hold data on. The data you hold on a screen is held until you delete it or until you log off the SAP system.
Note
The functions Hold Data and Set Data are not available for every task. If you try to use them in a task where they are unavailable, the SAP system displays a message in the status bar.
