it is an FM related to output control( NAST ).

check this example

tables : nase.

constants: appl like nase-kappl value 'V2'.

select-options:

rg_nacha for nase-nacha default '1',

rg_kschl for nase-kschl.

ranges: rg_objky for nast-objky.

data:

msgs_1 like msg0 occurs 100 with header line.

*-Fill Object Key

*-Execute fm

call function 'WFMC_MESSAGES_SELECT'

exporting

pi_application = appl

pi_processing = '1'

tables

ri_medium = rg_nacha

ri_type = rg_kschl

ri_object = rg_objky

tx_messages = msgs_1.

I don't know when but it seems to be a fm to get the print messages.

So:

PI_APPLICATION:

Application code: i.e which module the message is from

PI_PROCESSING:

How to make the messge: print, fax

PI_PRINTER: Device output

RI_MEDIUM

RI_TYPE

RI_OBJECT

RI_APPLICATION

here you can insert the ranges for selection of NAST table

TX_MESSAGES: Messages list: when a msg is created it's stored in NAST table, this parameter returns the selection from NAST table

Max

Check out the program <b>SD70AV2A</b>. the FM "WFMC_MESSAGES_PROCESS" is used in this program.

Hi!

Sorry all,to bother you again. I am still not clear what does what this function Module is doing.Can any one give a brief on it.

Actually my requirement is to change the standard program SD70AV1A,include two more fieds in the selection Criteria and Display them in the output.

In this program the function Module(WFMC_MESSAGES_SELECT) is called.I am not able to make out what this Function Module is doing.

Please give me as much detail as you can,since I am very new in ABAP.Will be thankful to you.

Sourabh,

this function module enables you to issue printout through Output determination. For example, lets say you have invoice that prints from VF01, VF02, etc using output type ZINV. This function module would let you print invoices from a background program. You would first use function module WFMC_MESSAGES_SELECT to get the messages from NAST and then pass it to this function module

thanks
