The ongoing discussion concerning the nature of the scalar resonances f_0(980) and a_0(980) implicated to extend the studies of the pp -> ppK+K- reaction near the production threshold. Furthermore, such elementary production processes allow to study the interaction of the outgoing particles due to their low relative momenta. Therefore, final state interactions in the pK or K Anti-K system can be perfectly studied in such experiments. The acquired data at the excess energies Q=10 and 28 MeV have been taken at COSY-11 and the status of the ongoing analysis will be presented.
