You have developed a ALV GRID report using REUSE_ALV_GRID_DISPLAY function and the report has come out really well. However, some users want to see a ALV list than the grid. Or you have a existing ALV GRID report and the user want to have a ALV List report.
SAP has provided a BADI just for this purpose. The name of the BADI is ALV_SWITCH_GRID_LIST . Now create a implementation for this BADI.
For a given user or specific to a report, you can switch on the flag to produce a ALV list.
Here is the simple code for the report.
TYPE-POOLS : SLIS.
DATA : T_DATA TYPE TABLE OF ALV_T_T2,
T_FIELDCAT TYPE SLIS_T_FIELDCAT_ALV.
SELECT * FROM ALV_T_T2 INTO TABLE T_DATA UP TO 30 ROWS.
Here if you have noticed, there are couple of important parameters that need to be passed. Those are IS_VARAINT and IS_LAYOUT . You have to set this field allow_switch_to_list to 'X' and also pass the username and report name in the IS_VARIANT field if you want to switch to the list based on the conditions.
