Side by Side Repeating fields do not align by sliding for printing
When printing multiple repeating side by side, the individual rows would align in previous versions up to FM11. In FM12, the individual rows no longer align. The sliding issue with the repeating fields has NOT BEEN CORRECTED in versions 1, 2 or 3. There is no work around for this issue. You can not create sections with multiple outputs on the same layout with related tables, only one. With repeating fields, you can create multiple and flexible outputs on the same layout.
If this behavior can not be restored, then the answer is simple, create a new command, ALIGN ROWS of multiple repeating fields that are chosen together to maintain their alignment when sliding.
Set up multiple repeating fields side by side with the repeating fields vertical. Use text for simplicity, but this occurs for all field types. Insert varying number of rows in each field. Select sliding based on above.
When the layout is previewed, the varying field heights should result in each set of rows from the multiple repeating rows to be horizontally aligned (much like a spread sheet)
Each cell of the repeating fields slide independently, based solely on the cell contents and not that of its neighbor.
When used for output layouts to show columns of data, the information is no longer aligned.
(Note that repeating fields can be used in ways that related fields can not, especially with reports. This can supplement and improve the output when printing reports of related records as well.)
No error message
There is no workaround for this issue, other than going into a report and manually adjusting the number of rows in each cell to get them to align. It really kills productivity.
