This is wrong. It should be the unique key of the dataset
(COD_TALHAO, I assume).

Leave KeySource Nil. You would use KeySource for a lookup key to a
different table. KeySource and MasterSource would never point to the
same datasource.

Correct the KeyLinks. That is the reference that is causing the
Multiple Rows error. And nil the KeySource property.

You have no JoinLinks, so ignore that.

If the MasterSource and MasterLinks settings are correct,
MasterSource should be pointing to the datasource for the
CTPROPRIEDADE dataset. The CTPROPRIEDADE dataset should have
COD_PROPRIEDADE as its KeyLinks.

Please go back to the sample that I sent you and follow what I did there.
