ALV-Grid not displaying changes to data structures

A quick tip when working with ALV-Grids or transactions that use ALV-Grids. Every once in a while when working on tables se16 and se16n weren't displaying changes I had made to my data structure and nothing I would do helped. Then all off a sudden hey ho everything was fine.

Last year I worked on a project with a colleague from SAP and he knew the solution. ALV-Grids have a built in cache. So changes to the data structure don't always appear instantly.

The report BALVBUFDEL will clear that cache. Just fire up se38 and run BALVBUFDEL and your ALV-Grid should display the changed data structure fine.
