F1 Help Provision 

Use

You are able to store a help text for each element in the Data Dictionary (DDIC) – independent of ALV. Wherever this DDIC element is used, the user is able to call up this help text with the F1 function key.

In the tree structure, you are able to specify any function  for the F1 function key.  We strongly recommend that you use F1 help here.

You are able to specify a “foreign” DDIC element to a column without DDIC reference and then to use the F1 help text from it for your column.
