Measurements of spin-azimuthal asymmetries in semi-inclusive deep inelastic scattering (SIDIS), where an electron scatters off a nucleon target at a high enough energy such that it can be described by scattering off a single parton in the target, emerged as a powerful tool for investigating nucleon structure and quark-gluon dynamics Recent studies of single-spin asymmetries in electroproduction at JLab suggest that their measurements may allow separation of different dynamical contributions, allowing separation of kinematical regions and different partonic contributions. Measurements of multiparticle final states in multidimensional space will be needed to sort out all disagreements with theory predictions and improve the phenomenology of 3D partonic distribution and fragmentation function. In this contribution, we will present ongoing studies and some future measurements with hadrons in electroproduction of semi-inclusive and exclusive final states at Jefferson Lab.
