Hello,
Here is how we handle this over here:
- we only use page at a time subfile (no load all)
- We retain in a variable the key of the first record of the subfile
- After the operation that might affect the records in the subfile (add, remove, change), we just reload the page from the value that we kept in a variable
We developed a series of routines to manipulate page at a time subfile and now we do not ever need to use load all subfile. That solves a lot of situation, like the one you are inquirering about (and the position to function is also handle by this approach).
Hope this help

Objet : subfile screen navigation: how to handle an "Add record" function
PGMA displays 10 records in a file using a subfile. Then the user pages down 4 times to show the last 10 of 50 records.
When the user presses F9 to add a record, I call PGMB to do that work, and then return to PGMA.
In PGMA, I would like to redisplay the last 10 of the now 51 records. Or maybe show the last 10 of 50, and a page-down will reveal the newest record.
It should also function properly if the user is in the middle of 50 records in the subfile, and does an add of the 51st record.
What is a good method to handle this? Or what is a common method that works?
Upon a record being added, do you re-load the SFL from the start? And load all 51 instead of loading the usual 10?
Other ideas?
Thanks!
