SAP Table Class Support for an Individual Table
The ability of WebFOCUS to access a given table is based on its class. Class can be found in the TABCLASS field in DD02L for this particular table. The following table classes are supported.
|
SAP Table Type |
Server Support |
|---|---|
|
TRANSP |
Maps to an individual SQL table (called transparent table by SAP). It can usually be accessed and read by the interface (see exception 1). |
|
INTTAB |
Describes a structure (called structure by SAP) that can be used by function modules, logical databases, and so on. There is no underlying data, and it is not supported by the interface. |
|
CLUSTER |
These tables (called cluster table by SAP) are supported, as long as they satisfy exception 1. |
|
POOL |
These tables (called pooled table) are supported, as long as they satisfy exception 1. |
|
VIEW |
Those tables are supported, as long as they satisfy exception 1, and all joined tables carry a supported table class. |
|
APPEND |
These tables are not supported. |
In addition, for all supported TABLE classes, they must be composed of a set of fields that have a supported data type. Unsupported data types are listed in exception 2.
Exceptions:
- If a field in a table is of type RAW, with a significant length (for example, field CLUSTD in table INDX), this may indicate that the field may be used for import/export using a program. Since there is no information on the underlying structure, this field can only be printed as an alphanumeric string. Its corresponding contents may not be meaningful on display.
- Unsupported data types: VARC, PREC, LCHR, LRAW, RAWSTRING.
