Hola,

Prueba esto:

Código Delphi [-]

procedure DuplicaReg( Dataset: TDataset);
var
 aField : Variant ;
 ANomCamps: Variant;
 i,numcamps      : Integer ;
 begin

 aField := VarArrayCreate( [0, Dataset.Fieldcount-1], VarVariant);
 aNomCamps := VarArrayCreate( [0, Dataset.IBTable1.Fieldcount-1], VarVariant);
 numcamps:=  Dataset.Fieldcount;

 For i := 0 to (numcamps-1) Do
 Begin
   ANomCamps [i] :=  Dataset.fields[i].FieldName;
   aField[i] :=  Dataset.fields[i].Value ;
 End;
 Dataset.append;
 For i := 0 to (numcamps-1) Do
 Begin
    Dataset.FieldByName(ANomCamps[i] ).Value := aField[i ] ;
 End;
 Dataset.Post;
 
end;

Puedes utilizar un IBDataset o un IBTable.
No olvides de hacer el commit
