We have two equipments A and B and want to make B a sub equipment of A.
Now, A has a maintenance plant set whilst B has an empty maintenance plant.
Trying to install B into A as sub equipment, I get an error message: IE009 (different plants not possible)
But when I use BAPI_INSTALL_EQUI, it works. The maintenance plant of A is being copied to B.
BTW: Installing an equipment to a functional location using IL02 does copy the maintenance plant of the funct. loc to the equipment.
Why does the BAPI behave different from the interactive transaction? Is there a way to teach IE02 to overtake the maintenance plant?
