Hello,

Even if the structure of the file changes dynamically, you can still read the file the same way as any other file.

I think the structure of the file will change depending on the business scenario.

So you need to find out the following things :

1. How many combinations of business scenario exists

2. Find out the possible file structure for each of the business scenario

3. Depending on the scenario, you know what the structure of file would be and read the file into an internal table accordingly.

4. Carry out further processing like any other file upload functionality.

Hi Feroz,

Do u mean that structure of the file on the application server is changing dynamically.

The following is the FM to read data from a file on Application Server.

OPEN DATASET FNAME FOR INPUT in text mode encoding default.

LOOP AT TAB INTO WA.

READ DATASET FNAME INTO WA.

IF SY-SUBRC 0.

EXIT.

ENDIF.

WRITE: / WA-COLUMN1, WA-COLUMN2.

ENDLOOP.

This is the FM to search the file on Application Server.
