Hi,
Depending on the structure definition, the radio buttons allowed in the dialog box are ready for input. Choose one of the possible enhancement categories:
<b>Cannot be enhanced</b>
The structure must not be enhanced.
<b>Can be enhanced or character type</b>
All structure components and their enhancements must be character-type (C, N, D, or T). The original structure and all enhancements through Customizing includes or through append structures are subject to this limitation.
<b>Can be enhanced or character-type or numeric</b>
The structure and its enhancement must not contain any deep data types (tables, references, strings).
<b>Can be enhanced in any way</b>
The structure and its enhancement may contain components whose data type can be of any type.
<b>Not classified</b>
This category can be chosen, for example, for a transition status; however, it must not be chosen for creating structures.
The rules for defining the enhancement category result implicitly from the structure setup and the classification of the types used. <b>These rules are as follows:</b>
If the object contains at least one numeric type or a substructure or component (field has a structure/table/view as its type) that can be enhanced numerically, the object can no longer be enhanced character-type, but is itself, at most, enhanceable character-type or numeric.
If the object contains a deep component (string, reference, or table type), or it contains a substructure or component that is marked as enhanceable in any way, then the object itself is enhanceable in any way.
If the object does not contain any substructure or component that is marked as enhanceable, you can select cannot be enhanced. If the structure has not yet been enhanced, you can choose the categorycannot be enhanced in any case.
If you are creating new tables and structures in the ABAP Dictionary, the system proposes the category can be enhanced in any way as standard value for the classification of the enhancement options.
If the developer chooses a more restrictive classification than can be enhanced in any way for a particular structure, then only the classification levels that adhere to the rules above are allowed. It is not possible to choose an enhancement option of a structure that is more restrictive than the classification resulting immplicitly from the structure setup and from the classification of the types used. Therefore, only the allowed categories are proposed for selection in the maintenance user interface.
If a structure depends on one or several other structures, the smallest category is chosen as implicit classification (in the order cannot be enhanced < can be enhanced and character-type < can be enhanced and character-type or numeric < can be enhanced in any way). This classification is greater than or less than the category in the other structures and also greater than or the same as the category that results from the actual setup in the original structure itself.
