MC62 characteristics value in sorted order

Hello,

We use MC62 to maintain Planning Hierarchy levels for Info structure (S901) at sold-to party & ship-to party levels.

In MC62 transaction, values for Sold-to party are not displaying in sorted manner (ascending or descending). Also in MC62, search button is grayed out. Due to this when there are lots of sold-to values maintained at any Prod Allocation object level then business user has to manually search for sold-to to double click & go to next level.

Is there any way to sort Info structure Characteristics values (in our case Sold-to) in MC62?

Any other suggestions are most welcome.

Thanks,

NRS
