Hi Susan,
Ok..So your first question about sequencing is answered..Comming to 2nd question, Please do the following.
1. Get the view name and attribute name of the context of the "Search for "field you want to change using F2.
2. Go to get_v method of the field.
3. There they would be making selection table. In selection table what ever field you want to display first, set the key for that as blank (like abap_false) and rest as 1, 2, 3 or in what ever sequence you want other fields to come.
Please let me know, if you still have any issues..
Regards
