Clearing the list created by 'WRITE' statement.

Former Member — Fri, 31 Aug 2007 14:22:14 GMT

Hello Experts,

What does a 'WRITE' statement do? Does it put data into spool or buffer or somewhere elser? Which one? And how to see this spool/buffer before the list is displayed on the screen? Also is there a way to clear this spool/buffer?

I have a requirement where I need to use 'Write' statement to create a list and then somewhere down in the program I need to clear this list before it is displayed on the screen.

Any suggestion?

Thanks

Bhupendra

Hi,

write statement just writes the data to the output.NO SPOOL IS GENERATED when you display a report through write.

if you want to generate a spool then press the print button on the menu bar.

i dont think you can clear the thingh you have written.

Instead you can again write ' ' repetedly on the same column row positions so that it will over write the data and write ' '.i.e space

please explain your question more clearly if you want some more help.

why do you want to write then clear before it get displayed???

thanks

good

The basic ABAP statement for displaying data on the screen is WRITE.

Syntax

WRITE can be

· any data object (see Data Objects)

· a field symbol or formal parameter (see Working with Field Symbols).

· a text symbol (see Maintaining Text Elements)

It is stored in a sort of "Buffer", you can write it and get the results in an internal table without having to either write to a spool, or write it to the screen. Here is an example program. internal table IASCII will have the output in readable format.



report  zrich_0001.

data: ilist type table of  abaplist with header line.
data: iacii type table of string with header line.

do 100 times.
  write:/ sy-index.
enddo.

call function 'SAVE_LIST'
     tables
          listobject         = ilist
     exceptions
          list_index_invalid = 1
          others             = 2.

call function 'LIST_TO_ASCI'
     tables
          listasci           = iacii
          listobject         = ilist
     exceptions
          empty_list         = 1
          list_index_invalid = 2
          others             = 3.

call function 'LIST_FREE_MEMORY'
     tables
          listobject = ilist.

* You have the list in the IACII internal table, now you can
* avoid the output to the screen using this statement.
leave list-processing.

Hi,

I need to export the list (created by 'WRITE' statements) to memory and then read the memory to pass it to workflow. Then I need to create a different list and then export it again to memory so I need to clear (or delete) the previous list.

Thanks
