  We revisit the next-to-leading order (NLO) perturbative QCD corrections for
the deeply virtual meson production (DVMP) process, exploring its phenomenology
both in isolation and in a multichannel fit combined with deeply virtual
Compton scattering (DVCS). Our approach involves the conformal partial wave
(CPaW) formalism, which allows for the straightforward inclusion of
higher-order contributions and evolutionary effects. Our findings indicate that
a description of the longitudinal component of the vector meson DVMP
cross-section at high energies is achievable only at NLO within the standard
collinear approach. Furthermore, we demonstrate a simultaneous description of
DIS, DVCS, and DVMP processes, providing insights into the proton structure
described at NLO by unique universal generalized parton distribution (GPD)
functions.
