We study the correlation functions of the B0 D+, B+ D0 system, which develops a bound state of approximately 40 MeV, using inputs consistent with the Tcc(3875) state. Then we address the inverse problem starting from these correlation functions to determine the scattering observables related to the system, including the existence of the bound state and its molecular nature. The important output of the approach is the uncertainty with which these observables can be obtained, considering errors in the B0 D+, B+ D0 correlation functions typical of current values in present correlation functions. We find that it is possible to obtain scattering lengths and effective ranges with relative high precision and the existence of a bound state. Although the pole position is obtained with errors of the order of 50 % of the binding energy, the molecular probability of the state is obtained with a very small error of the order of 6%. All these findings can serve as motivation to perform such measurements in future runs of high energy hadron collisions.
