column 1;

column 2: one to many with table B(partner_id)

}

table B{

Column 1;

column partner_id many 2 one with table Acolumn 3;

column 4: one 2 many with table C(package_id)

}

table C{

column 1;

column package_id: Many 2 one with table B;

column 3;

}

over here i am not able to sync the table C with column 4 from table B and in both table B and C  i am providing the Authority of table A. Any help regarding these would be helpful.
