Manish Prakash Staff asked 5 years ago

The module which are loaded first, they configuration is taken in memory.
e.g if two modules have same xml config tags

Mod_A has global->field = value1
Mod_B has global->field = value2

if Mod_A loads first, the final value in configuration would be value1

this is true of overrides, field set, system.xml values etc which we do
