How to generate a empty file in AL11 using ABAP and unix command

Question

Hi Experts,
when load infopackage triggers it will search file from AL11 if file is available it will get loaded successfully.  When there is no file in AL11 error while opening file (orgin A) and the load will fail.  At this level i have to write a abap code using unix command to generate a empty file.
Is there any way to achieve the above requirement.
Thanks

Hi,
If i get your requirement properly then you want to create a blank file if there is no file on the application server so that your infopackage does not fail, am i correct.
If this is your requirement then this can be easily done if you use process chain to load the file via infopackage. Follow the following steps:
1. Add a ABAP program before the infopackage and check if the file is present on the server or not. Use a simple ABAP statement OPEN DATASET <FNAME>. Check the SY-SUBRC after this statement if it is not 0 then it means that the file does not exist on the application server.
2. Once you have established that the file is not present create a flat file using a code similar to the below one
OPEN DATASET FILENAME FOR OUTPUT IN TEXT MODE
                      MESSAGE D_MSG_TEXT.
IF SY-SUBRC NE 0.
  WRITE: 'File cannot be opened. Reason:', D_MSG_TEXT.
  EXIT.
ENDIF.
* Transferring Data
LOOP AT INT_table.
  TRANSFER INT_table-field1 TO FILENAME.
ENDLOOP.
* Closing the File
CLOSE DATASET FILENAME.
3. Add your infopackage step after this ABAP program in your process chain.
I hope this helps.
