REUSE_ALV_GRID_DISPLAY save data

Hi,

I use REUSE_ALV_GRID_DISPLAY to display a database-table as an ALV-GRID.

I made some cells of the ALV editable by using a fieldcatalog.

Now it should be possible to update the data of the database-table with the data of

the ALV-GRID.

Can you help me?

Best regards & Thanks in advance
