Missing Info Objects in Business Content

Hello,

the business content of our system has missing IO. For the Bank Analyzer there are missing 3 IO which are used for the cube etc.(IO are S20BPART,S21DFVAL, S40FTRAN).

For me is this problem new and I want to now if anybody has experience with this type of problem. On oss I could not find anything, so what could be the reason

Thanks

Henning
