Operation number and work center

I'm looking for the link between inspection plan/recipe header and operation at table lavel.

Reason: I have two inspection plan number with same group number but both has different counter and each has 4 operation and each operation has different work center.

Now I can get header info in PLKO and operation level info in PLPO table. From PLKO I can pass PLNTY and PLNNR in PLPO table but this gives me 8 entry in PLPO table (4 for 1st group counter and 4 for 2nd counter).

So my question is how to differentiate 4 operation of each inspection plan header. Even same issue facing at recipe level.

I can't find any table. Do we have any BAPI?
