Dependencies
Some data classes have a fixed length. For example, the data class CLNT (client) always has three places. If you enter an invalid length for such a data class, the system will give you a warning and then correct the error automatically.
The types RAWSTRING and STRING for LOB s have a variable length. A maximum length can be specified, but there is no upper limit. The maximum length is an actual length that cannot be exceeded. The maximum length is used for optimizations when storing string fields in the database.
The type SSTRING also has a variable length, but this is restricted upwards by the maximum length that can be specified. The greatest maximum length is 1333. The benefit of using it, and not CHAR, is that it is assigned to the ABAP type string. Its advantage over STRING is that it can also be used for key fields in database tables.
When using data types from ABAP Dictionary which are based on the predefined types RAWSTRING, STRING, and SSTRING, you have to consider in ABAP programs that the maximum lengths defined in ABAP Dictionary have no effect on the assigned ABAP types string and xstring. As a result, writing a string that is too long to a database can raise an exception. If required, you therefore have to apply a length restriction for strings in ABAP programs, for which the predefined function dbmaxlen can be used.
