An ALV report is created using the standard function modules provided by SAP.
An ALV report can be created using the following steps.
- Include SLIS type pool – SLIS type pool contains all the data types required by ALV function modules.
- Data retrieval – Code the logic to fetch the data from database table into an Internal Table.
- Build Field Catalog – Add the columns into an internal that you want to display in the ALV output list.
- Pass the data table and field catalog table to ALV function module
TYPE-POOLS: slis. " SLIS contains all the ALV data types
