regarding back ground job

Hi friends, this is very urgent. plz help.

my requirement is i want to create a report and in selection screen it should have a ONLINE and BATCH radio buttons. if i select ONLINE it has to run in onine mode. if i selecet BATCH , it has to run in batch mode. my specification id like this ;

1. If online mode, we will have a parameter in YTXXTTFVAR table that can control the number of entries that can be validate online.

YTXXTTFVAR layout:

MANDT(3): 100

ZSYSTEM(8): H00

ZPROG(40): YTXXP238

ZENTRY(20): MAXLOAD

ZSEQNR(3): 001

ZENTRYDC(40): Number of entries validated online

ZVALUE(45): 1000

The default value for this parameter is 1000. If this is exceeded in the upload sheet then the program needs to automatically switch to batch mode.

The summary report with success/error messages is displayed on screen

2 If batch mode, a job will be created. The job will follow the following naming convention: HQEC_YTXXP238_UPLOAD_LASTLOADNUMBER.

The LASTLOADNUMBER is a parameter that we define in YTXXTTFVAR table and its value is increased each time a new job is created.

YTXXTTFVAR layout:

MANDT(3): 100

ZSYSTEM(8): H00

ZPROG(40): YTXXP238

ZENTRY(20): LASTLOADNUMBER

ZSEQNR(3): 001

ZENTRYDC(40): Last used job load number

ZVALUE(45): 1000
