interfaces

[Former Member]

Hi all,

I have a few questions on interfaces...can any one provide the solutions for these please..

- What are physical and logical file paths and names.

- how do we recognize whether the files are stored in Application server or presentation server

- What are external system id's and where are they used.

- How to access application server.

And can any provide the detailed flow of a interface with the ABAP terminology.

Thanks

Go in transaction FILE, that will give you the link between logical and physical paths.

Ex: TMP --> /tmp (logical --> physical)

By default, the system uses the logical file name ARCHIVE_DATA_FILE and the logical path name ARCHIVE GLOBAL PATH as defaults. Consequently, the names only need to be changed if they have to be adjusted to meet special requirements.

Hi,

Physical file name means which u enter the path of the file.

Logical file means unix path which displayed in AL11 t-code.

Relation is defined in the FILE t-code.

Hope this helps you. Reply for queries, shall post the updates.
