Long Names
Use
The extended namespace is supported since Release 4.0. This concept includes the use of prefixes and long names. The following objects in the IDoc interface are affected by long names:
Object |
Length in 4.0 (characters) |
Length before 4.0 (char.) |
Message type |
30 |
6 |
IDoc type (basic type or extension) |
30 |
8 |
Segment |
27 |
7 |
Each object has a conversion table which is maintained in Customizing.
Activities
Determine which objects you want to exchange with older releases or an R/2 System and check whether these include objects with long names which are not supported by these releases. You should then maintain the corresponding Customizing tables.
If you have defined extensions in Release 4.X and want to use long names, you must maintain the corresponding conversion table for extensions in Customizing. Alternatively, you can define extensions with short names to be used only for exchanging data with older releases.
