PIC01 - Search of Field "FFF Class"

Hi,

I have some FFF Classes created by MM01.

Whenever I go to t-code PIC01, I try to search (F4) for these classes, but only one appears.

The others are created in the same way. It looks like an error of the search in the field "FFF Class"... Any advice you can give me in order that if i search, all the classes are listed??

Thanks and Regards,

MC
