Fiori Launchpad showing Blank

Hi All,

I am having a issue, fiori launchpad showing blank even after assigned the roles related to Fiori and also the rfcacl authorization object.

roles: sap_ui2_user_700

Sap_mm_tcr_t_x1

Sap_mm_bcr_buyer_x1

for the time being when i assigned the SAP_ALL profile it is showing other wise it is not showing the tiles on the launchpad. it is not showing the Groups or catalogs also when no sap_all authorization to the user.

Please suggest what authorizations are required to the user in frontend. Because sap_all is not the best way to assign the all users.

Thanks in advance.

Thanks&Regards,

Praveen.
