                      Neutron Scattering (SANS) $\&$ Grazing-Incidence-SANS are
                      often connected to complexanalysis procedures and require
                      the development of individual magnetic models. Additionally,
                      precisedata-reduction protocols are needed to distinguish
                      sample scattering from instrumentationaleffects. The more
                      involved the different interactions in one sample system,
                      the more care has tobe taken for a comprehensive
                      understanding as function of, e.g., magnetic field, electric
                      field, temperature,and further parameter sets. The key to a
                      broad understanding then can be given by thecomparison of
                      various analysis methods.Here, I will provide two examples
                      on the complexity of magnetic (GI-)SANS data analysis on
                      differentmaterials: (i) a ferromagnetic/superconducting thin
                      film with temperature dependent chiralmagnetic domain walls,
                      and (ii) a magnetoelectric single crystal with chiral
                      magnetic phases dependingon temperature, magnetic, and
                      electric field. For study (i) we will compare
                      polarization-analyzedGISANS data on Nb/FePd thin films with
                      perpendicular magnetic anisotropy with results from
                      CDXRMS,and evaluate our conclusions together with
                      information gained by Density Functional Theory(DFT) [1]. In
                      study (ii), we present the dependence of magnetic chiral
                      phases occurring in the magnetoelectricsingle crystal
                      Ba2−xSrxMg2Fe12O22 [2] as function of temperature and
