LSMW create positions without updating table T528B?

I created many positions by LSMW,

but, in PA40, I can't assign a person to any one of these LSMW-created positions, system says "position xxxxxxxx is not available in T528B",

I've set integration between PA & OM, if I manually created position in PPOME or PP03, the manually created position could be assigned in PA40

So, how could it happen? SAP's bug or our system's bug?

I have to run report RHINTE10 to update T528B.
