Hi "Panobois",
I think, this issue better fit to the Developers Forum.
The answer generally is that you can use the FDA Designer Tool to accomlplish.
1.) You can override the sequencing of the Grid.
2.) You can enable the QBE on the Grid Properties window.
3.) Maybe you have to add the Short Item Number (ITM) BSVW field to the grid if you want to sort on it.
4.) ... and of course, see Sef's hints too.
Other considerations:
1.) You can sort only on BSVW columns but not on derived columns.
2.) On some forms the mentioned methods does not work when the application fill up the Grid programatically.
3.) On some Forms changing the sequence could cause problems when there are some special logic based on the hard-code sequence (e.g. totaling, etc.)
4.) Applying additional filtering also can cause problem when the logic requires to handle all line together (sometimes Master Business Functions requires this).
I have taken a glance to P4205 (just a glance!) and it seems so that you can enable QBE, add Short Item Number to the Grid and change the sequencing. Please, do not consider it a guarantee.
On the other hand, when the QBE is enabled then the Sequencing will be also enabled for the user on the grid.
Good luck,
Zoltán
