3748437 - Availability check (MTVFP) field mandatory in OMSR not enforced unless MARCATP is changed in MDG Material Governance.

• While creating or changing material in MM01/MM02, an error indicates the Availability Check field is mandatory.
• The Availability Check field is configured as mandatory for a material type in OMSR.
• The Availability Check is stored in MARC but is not part of the MARCBASIC entity; it is in the MARCATP entity in the MDG data model.
• When plant data is maintained in MARCBASIC and MARCATP is not maintained, no Availability Check error is raised.
• If any value is maintained in MARCATP and the Availability Check is left empty, an error occurs.
• In class CL_MDG_BS_MAT_ACCESS, method CHECK_MANDATORY_FIELDS, validation loops only through entities extended in the MDG Change Request (staging). Dependent entity validations (such as MARCATP) fail if not explicitly extended.
• OMSR validates mandatory fields at the MARC table level, but dependent entity validations are not automatically considered when only MARCBASIC is extended.
