  • What causes this issue?

    You want to change the data type of field &V1& from &V2& to &V3&. It
    makes no sense to convert the values of these data types and therefore
    it is not technically possible using ABAP means. You therefore cannot
    convert the table with this structure change.

    System Response

    The table is not successfully checked or activated.

    How to fix this error?

    You cannot convert the field contents of the one type to the target
    type by conversion. The only option is to add a new field of the target
    type, which of course is not yet filled with data.
    The field of the old type that is already in the table can be deleted
    if necessary.
