Today in the SALV model tutorial series, we will see how we can change the Column properites. You can find all the previous discussion in this series can be found at Tutorials > SALV Table Display .
To change the propeties of the Columns first we need to get the Column object from the SALV Object. The reference of the column object would be CL_SALV_COLUMNS. This object reference would provide us the access to the properties of all the columns. For example, if we need to set the column width optimization for the table, we can set using this columns reference.
To change the individual column properties, we need to get the individual column reference from the reference created using the CL_SALV_COLUMNS. The individual column property can be changed by the getting the reference of CL_SALV_COLUMN. Like, to change the column heading, we need to first get the column from the Columns object and than we need to set specific property.
Here is the code snippet to which provides the ADD-ON code to our Base program. The base program can be found in the SALV Model 1: Normal ALV Table Display .
UML Diagram would be like:
