FYI
ALE Interface
The following objects are generated from the application function module:
· Message, IDoc structure and segments: Mapping of the complex data type
· Outbound function module: Each IDoc always contains one application object only
· Inbound function module: IDocs are always transferred to the application individually or in packets of objects.
· Customizing objects required for the run
Assigning names to generated objects
· Default message (maximum 30 characters) proposed from the function module name.
· IDoc (maximum 30 characters) is derived from the message – the last two characters are extended by 01 (message <= 28 characters) or are replaced by 01 (message > 28 characters).
· Generated function module name
Outbound (maximum 30 characters): ALE_function module name (default)
Inbound (maximum 30 characters): IDOC_INPUT_message (default)
· Segments
The default segment name begins with E1 for SAP and Z1 for customers, or namespace /.../. A meaningful and unique segment name is assigned as follows:
- In the application system (maximum 27 characters):
The segment name is derived from the structure name:
· If the structure name is shorter than 24 characters, the segment name is copied directly.
· If the structure name is longer than 23 characters, it is shortened to 23 and the “less important” characters at the front are cut off. The remaining characters are used to form a number that establishes the uniqueness of the shortened name. If numbers 01 to 99 are used, assignment continues with numbers 100 to 999 until the segment name becomes unique. This ensures that new segment names are created for the same structure, when this structure is used many times in a complex data type.
Hope this’ll give you idea!!
P.S award the points.
Good luck
Thanks
