We recently upgraded to 2025R2 and set our site to use Modern UI everywhere. Some of our row sets use alphanumeric row codes (“1010A”) and this was causing an error: “Input string was not in a correct format.” The row set was unable to be edited without reverting the Row Sets screen (CS206010) to the classic UI. I then had to manually edit the row codes and formula references. The row set was then able to be converted to the modern UI.
Can anyone at Acumatica confirm if there is a fix coming for this? All of our other row sets converted to modern UI without issue.
