run in background

former_member445510 — Tue, 05 Aug 2014 13:39:12 GMT

Hello,

This program works good in Foreground, can some one help me to execute it in Background?

I tried via sm37 - sm36 (job wizar) - right button execute in Background, but it doesn't succeed.

It's work perfect in Foreground...

Hi,

the problem is that not every report is made for run in both modes. you need to identify the "bug" in your programm. if its a sap-programm and there is nothing mentioned in the description i would ask sap for help.

if its your own programm i would write a logfile at important programm steps to check things because you can not debug a programm running in background.

How

It depends on you need to do

You need to considere all interactions with the GUI has your pc (Presentation) as reference, this reference can't exist in background (because the program works on server (Application)).

So you need to replace every action with GUI with the corresponding action with Application: for exaple

if you get a file from your PC or network (in generally from Presentation), in background you should pick up the file from Application Server

the xml file 'FI_Extract_1000_20140804_144444_295.XML' i pick it up from Application server !!!

i have this code in my program...

p_filref = '\\SAPSERVER\f\SAFT\ivat\FI_Extract_1000_20140804_144444_295.XML'.

in AL11, i have directory 'ivat' where i store my xml file..

Re: run in background

Former Member — Tue, 05 Aug 2014 14:36:21 GMT

It doesn't mean the directory doesn't exist If you can't see a directory by AL11

AL11 shows only the mapped directory, anyway:

\\SAPSERVER\f\SAFT\ivat\.....doesn't seem a right path... Can you see \\SAPSERVER\f\SAFT\?

How do you read the file?

i renamed the the directory ivat to IVAT.

i read file with the class method import_from_file.

create object gcl_xml.

*Upload XML File
   call method gcl_xml->import_from_file
     exporting
       filename = p_filref
     receiving
       retcode = gv_subrc.

   if gv_subrc = 0.
     call method gcl_xml->render_2_xstring
       importing
         retcode = gv_subrc
         stream = gv_xml_string
         size    = gv_size.
     if gv_subrc = 0.

       refresh gt_xml_data[].

* Convert XML to internal table
       call function 'SMUM_XML_PARSE'
         exporting
           xml_input = gv_xml_string
         tables
           xml_table = gt_xml_data
           return    = gt_return.
     endif.
     endif.

Which is the class?

Re: run in background

former_member445510 — Tue, 05 Aug 2014 14:48:43 GMT

sorry, i mean object method....

Re: run in background

Former Member — Tue, 05 Aug 2014 14:53:45 GMT

Hi,

does your programm generate a logfile if the file exists and got up/downloaded correctly?

if yes and everything is correct this wont be the issue.

Re: run in background

Former Member — Tue, 05 Aug 2014 15:03:38 GMT

Yes

I've understood that, but I don't know the code of method gcl_xml->import_from_file, so can you give the class of the object gcl_xml?

Is it a local class? If it's so you should post the code of the method

Is it a global class? If it's so you should give the class name

I do the following steps in my program:

- i make reference to a xml file stored in application server \\SAPSERVER\f\SAFT\IVAT\test.xml

- i make automatically extraction of data with extractor program using the statement Submit stored in directory in application server

- i import the both xml files to internal table

- i compare the both internal tables if they have the same data or not.

. if there is difference - > i send Email to my outlook inbox saying 'there is a difference in data'

. if there is NO difference - > i send Email to my outlook inbox saying 'there is NO difference '

But i don't generate the logfile !!!

this is the code of the method:

Re: run in background

Former Member — Tue, 05 Aug 2014 15:20:51 GMT

Good

the problem is here:

call method cl_gui_frontend_services=>gui_upload

As I said before this method works online only, I can't work in background:

that method find the file in your Presentation Server, not in Application Server

So you need to change your program in order to run in background and read the file from Application, something like this:


method import_from_file .

   data: lt_data    type swxmlcont,
         l_filename type string,
         l_size     type i.


if p_application = 'X'.

*
*  call function 'WS_UPLOAD'
*       EXPORTING
*            filename   = filename
*            filetype   = 'BIN'
*       IMPORTING
*            filelength = l_size
*       TABLES
*            data_tab   = lt_data
*       EXCEPTIONS
*            CONVERSION_ERROR        = 1
*            FILE_OPEN_ERROR         = c_not_found
*            FILE_READ_ERROR         = 3
*            INVALID_TYPE            = 4
*            NO_BATCH                = 5
*            INVALID_TABLE_WIDTH     = 6
*            GUI_REFUSE_FILETRANSFER = 7
*            CUSTOMER_ERROR          = 8
*            others                  = 99.
*

   l_filename = filename.
   call method cl_gui_frontend_services=>gui_upload
      exporting
        filename                = l_filename
        filetype                = 'BIN'
*      HAS_FIELD_SEPARATOR     = SPACE
*      HEADER_LENGTH           = 0
      importing
        filelength              = l_size
*      HEADER                  =
      changing
        data_tab                = lt_data
      exceptions
        file_open_error         = c_not_found
        file_read_error         = 3
        invalid_type            = 4
        no_batch                = 5
        gui_refuse_filetransfer = 7
        others                  = 99.

   retcode = sy-subrc.

   if retcode = 0.
     retcode = create_with_table( table = lt_data size = l_size).
   endif.
else.
   opend dataset i_filename <option you need>.
   do.
      read dataset i_filename  into it_data.
      if sy-subrc <> 0. exit. endif.
      append it_data.
   enddo.
endif.


endmethod.

But you need to know where the file is saved in your application

thank u,

example of application server is that?

Re: run in background

former_member445510 — Tue, 05 Aug 2014 15:42:47 GMT

i do this code in comment, and i added your code as following:

* create object gcl_xml.
*
**Upload XML File
* call method gcl_xml->import_from_file
*    exporting
*      filename = p_filref
*    receiving
*      retcode = gv_subrc.
*
* if gv_subrc = 0.
*    call method gcl_xml->render_2_xstring
*      importing
*        retcode = gv_subrc
*        stream = gv_xml_string
*        size    = gv_size.
*    if gv_subrc = 0.
*
*      refresh gt_xml_data[].
*
** Convert XML to internal table
*      call function 'SMUM_XML_PARSE'
*        exporting
*          xml_input = gv_xml_string
*        tables
*          xml_table = gt_xml_data
*          return    = gt_return.
*    endif.
*    endif.

DATA lt_data type swxmlcont WITH HEADER LINE.

open dataset p_filref FOR OUTPUT in TEXT MODE ENCODING DEFAULT .

    do.

       read dataset p_filref into lt_data.

       if sy-subrc <> 0. exit. endif.

       append lt_data.

    enddo.

i get just "Starting tool..." without result

Re: run in background

Yes

You need to do that

Now you're looking a file in your Presentation, so in a directory of your network:

\\SAPSERVER\f\SAFT\IVAT\

so you have to speak about that to your basis, because if SAPSERVER is the server of SAP it belongs to Application too, but perhaps the path can be called in different way

Try to use this fm:

/SAPDMC/LSM_F4_SERVER_FILE

here you can see all Application Server, so you can see also the paths not mapped in AL11

Re: run in background

Former Member — Tue, 05 Aug 2014 15:46:32 GMT

That's ok

but you make sure the value in p_filref:

Usually the value is different if it's a path from Application or path from presentation
