Bypass XI for Interfaces

[Former Member]

Dear All,

We have arround 135 interfaces which will be designed with XI. There is not validaation and error handling of data in XI simply it is passing to R3 system.

Now client has suggestion that to by pass the XI and directly send the data to/from R3 from legacy system. 90% of scenarios are file.

I have few questions to be clarified:-

1. How the files will be put and picked up from the Legacy system. Does the Legacy application put/pick the file directly on ABAP application? If yes then How Legacy system will take care of it. (Most of the Legacy system is using FTP server). Does we require any third party System which will pick n put the file for Legacy and ABAP system.

2. How the monitoring of the messages will be taken care as we have many no of Interfaces. How to make sure that which all records has been updated in to ABAP database successfully and which all are not? In this case it will be very difficult to make out where the issue is

3. What are the risk and effort invovled with this appraoch.

4. How the performace with is appraoch on Prod system.

Thnx

1) Abap system can fetch file directly and put file in designated folder ,you have to make the FTP folder as NFS , or use application server as an FTP server . and you have to schedule jobs on r/3 server to run and pick the file.

2) monitoring is not possible, instead you can put validations and mail firing from abap in case of failure.

3) risk is high and if your legacy systems are having different servers then effort is also high...

4) performance will not be an issue...

Hi,

(1)Depends on your Legacy file on User Local machine( presentation) or Remote system.

If it is available on user local machine then there are many standard functions like 'ALSM_EXCEL_TO_INTERNAL_TABLE', 'GUI_UPLOAD' are available for uploading Legacy data.

If it is availabe on Remote machine then by using the FTP Conection you can read/write the Legacy Data.

Some Standard SAP FTP related FM are 'FTP_CONNECT', 'FTP_COMMAND','FTP_CLIENT_TO_R3'.

(2)There is no any direct monitoring Tool is available in SAP R/3, only option is create the 'Z' table in R/3 and maintan the Transferred Data and Flags there.

(3)Effect involved is more compare to Iinterfacing through XI ( For example: Creating the 'Z' table for

Data Monitoring).

(4) Performance point of view there is not much difference.

Thanks
