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 the ALE development menu.  

Activities

  1. 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. Maintain the corresponding 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. Alternatively, you can define extensions with short names to be used only for exchanging data with older releases.

Choose SAP-Menь ® Tools ® IDoc/ALE ® Development ® IDoc ® IDoc Type Development ® IDoc Types (WE30) to convert IDoc types and message types.
