There is no reaction and so there is no net ionic equation.

Explanation:

Balanced equation

#"3KCl(aq) + (NH"_4)_3"PO"_4("aq")"##rarr##"K"_3"PO"_4("aq") + "3NH"_4"Cl(aq)"#

Complete ionic equation

#"3K"^(+)("aq")+"3Cl"^(-)("aq")+"3NH"_4^(+)("aq")+"PO"_4("aq")"##rarr##"3K"^(+)("aq")+"PO"_4("aq")+"3NH"_4^(+)("aq")+"3Cl"^(-)("aq")"#

There is no reaction. All of the ions are aqueous. In order for a double replacement to occur, one product must be a precipitate, insoluble gas, or water.

What you have is a mixture of aqueous ions. The equation should be:

#"3KCl(aq) + (NH"_4)_3"PO"_4("aq")"##rarr##"no reaction"#
