Hi Naveen,
first of all, you can use the APF generic runtime to launch an APF configuration that you created using the APF Configuration modeler. When you want to launch an APF application from a Smart Business KPI tile, it is perfectly fine to use FioriApplication and executeAPFConfiguration in the navigation section of the KPI tile creation screen.
Now, if you want to assign your tile to other users you need to make sure to not only assign the group/catalog of the KPI tile but to assign the role/ catalog for the generic runtime as well.
Depending on your system landscape (SAP Business Suite powered by SAP Hana or S/4 Hana) you have to assign the following catalog/role to the user:
SAP Business Suite powered by SAP Hana: Catalog SAP_APF_RT_TC_A / Role SAP_APF_RT_TCR_A (see also http://help.sap.com/saphelp_uiaddon20/helpdata/en/ec/f70adefd71445586b2fbe264306fdd/content.htm?frameset=/en/57/ae108454d643f6b6e1e364144b1433/frameset.htm¤t_toc=/en/e4/843b8c3d05411c83f58033bac7f072/plain.htm&node_id=947)
S/4 Hana:catalog SAP_CA_BC_APF_EXECUTION (see alsohttp://help.sap.com/saphelp_uiaddon20/helpdata/en/57/ae108454d643f6b6e1e364144b1433/content.htm?frameset=/en/ec/f70adefd71445586b2fbe264306fdd/frameset.htm¤t_toc=/en/e4/843b8c3d05411c83f58033bac7f072/plain.htm&node_id=948)
