hi
This piece of code might be useful.
The following sections will help you to understand the steps required to define a Dynamic ALV.
Following symbol signifies:
Þ Important
Main Steps Required
The following are the main steps that are to be performed for defining a dynamic Alv
1. Defining a field catalog
2. Defining the dynamic table
3. Filling data into the table
4. Displaying ALV list
Defining a field catalog
The purpose of defining a field catalog first in case of Dynamic ALV is somewhat different than in case of normal ALV. In case of Dynamic ALV the field catalog is used to define the final internal table that will hold the data, and would be used to display the final output.
Þ It is very important to remember that the field catalog table be refreshed first, else it might give an error.
For example:
DATA: T_FIELDCAT TYPE LVC_T_FCAT,
L_FIELDCAT TYPE LVC_S_FCAT.
Refresh T_FIELDCAT.
CLEAR L_FIELDCAT.
L_FIELDCAT-FIELDNAME = 'LIFNR'.
L_FIELDCAT-INTTYPE = ''.
L_FIELDCAT-OUTPUTLEN = 10.
L_FIELDCAT-COLTEXT = TEXT-002.
APPEND L_FIELDCAT TO T_FIELDCAT.
Defining the dynamic table.
This table will hold the final data that needs to be displayed. To declare the table the following things need to be done.
Declare a field symbol
Displaying Alv List
This is done in the same way as we do for normal Alv. Call function “REUSE_ALV_GRID_DISPLAY” and pass the field catalog table in the export parameters and the dynamic table in Tables.
And also chexk the following link
you can do that.
