If you want to see if the user is running the program in the foreground:

sy-subty = 4.    “Call type for submit

otherwise it is a background submit.

* EXAMPLE:  Display the GUI status if run in foreground otherwise don’t

if sy-subty = 4.     

  set pf-status 'GH'.

endif.               

There are at least three ways that I know of that you can transport a variant for a program.

• When you first transport a program, all elements of a program are transported along with the source code.  This includes any variants that have been created at this time
• After the first time a program has been transported, there are two ways to move a variant.  The first method is to manually add an entry to the transport for the variant you want to move.  The format of the entry is LIMU VARX xxxxxxxxName_of_the_variant where xxxxxxxx is the program name.
• The last method is the easiest, in that you do not have to remember any arcane codes.  Go to the ABAP editor, and go to the variant screen.  Under the Utilities menu is Transport Variant.  This allows you to choose the variants to transport, and the transport to put them in.

• Use SM31, enter the table name.
• Click on Customizing.
• Enter an IMG project, or click w/o proj button.
• Click enter. Gives you IMG path(s) which lead to updating given table.

Before calling DOWNLOAD, GUI_DOWNLOAD or WS_DOWNLOAD, do a perform SET_TRAIL_BLANKS(saplgrap) using 'X'. To set the length of each record including your blanks add this code: perform SET_FIXLEN(saplgrap) using '0' '100'

Set parameter ID ‘AUN’ field vbak-vbeln.  "Sales order parameter ID

Call transaction ‘VA03’ and skip first screen.

Please note, this tip does not appear to work in versions of SAP >= 4.6. It is very easy to hide your source code in ABAP. Simply enter *@#@@[SAP] on the very first line of your program. This text should be the only text on the line. There is no easy way to get your source code back, so make sure you make a backup and save it to a local drive!
