Anyone familiar with this?  I've checked my data; no errors evident. Return does not have a T2125.

280010 : Line 9946 for net income (or loss) on this selected financial data (SFD) record does not balance with total income minus total expenses, multiplied by the percentage share of the partnership, if applicable.
This error may also set when there are entries on lines that do not relate to the SFD type. For example, lines 8300, 8320, 8340, 8360, 8450, 8500, 8518 and/or 8519 relate to the Form T2125 when the SFD is type 02 for business or commission operations, but do not relate to the Form T2125 when the SFD is type 03 for professional operations.
