You can modify the field definitions in a table layout if the data source they connect to changes, or if you want to change how a field is formatted.
Analytics restricts changes to field definitions if they are referenced by a computed field. In this case, you are prevented from changing the field name or data type, but you can change other properties, such as start position or length.
To modify a field in a table layout:
- Select .
- In the Edit Fields/Expressions tab, double-click the field you want to modify.
- Make the necessary changes to the field definition and
click Accept Entry
.
For more information about field definitions, see Define a physical field.
