Getting RFKK_MA_SCHEDULER parameter values

Question

Anyone who is familiar on how to get the parameters from SAP standard transactions? Variant is currently saved and is being passed and executed at RFKK_MA_SCHEDULER I need to collect the ranges on parameter to edit it on runtime.

Function module FKK_FPYM_READ_PARAMETERS is being used at Event 1906 to get parameters/ranges that are set then I will do some Select statements that will make my own list and I will use FKK_AKTIV2_PARA_BASICS_TO_DB to update the parameter and enter my list instead of the variant template.

This would make the process more optimize. The problem is FM FKK_AKTIV2_PARA_BASICS_TO_DB does not contain parameter "E_ADDONS" from the read parameter FM. Any other workaround?
