  • What causes this issue?

    Object &V1& is to be processed, but it is frozen. It is either part of a
    released interface or released itself (in the case of function modules).
    Object &V1&, therefore, may only be processed as a compatible object.

    System Response

    Operations that would cause an incompatible change will be refused.
    Incompatible changes include, in particular, deleting frozen objects or
    subobjects.
    Objects that contain a call interface (function modules or methods) are
    only allowed to have optional input, changing, or table parameters added
    to them, in addition to output parameters. Adding further exceptions or
    changing existing parameters is not allowed.
    In the case of non-final classes, adding methods is not allowed either
    because of the inheritance problems involved; however, implementing an
    additional interface is allowed.

    How to fix this error?

    In justified cases, incompatible changes can be approved by QM and
    interface experts (enhanced HOTPACKEXC exception procedures).
