table control top line problem

Hi All

I have a problem with a table control and setting cursors and the top line.

I have a table with 10 lines and only 4 are visible at a time.

I scan a material and i set the cursor to the field where the user can enter a quantity.

My problem arises when the material I scan is not in the first four visible items of the table control.

If the material is item 8, I do a scan, i set the top line of the table control to the material index in the pai and then in the pbo

i set the cursor field to line 8.

The top line is set correctly but the cursor field is not set.

I use set cursor <fieldname> line <line No>

Any help would be great

Thanks
