- Spool List Levels and Spool Requests

Every output to a spool list is assigned to exactly one spool request. For every spool request, spool parameters are specified that can no longer be changed. Spool lists can be stacked in spool list levels. A spool list level always has exactly one spool request assigned to it.

Spool List Levels

The following operations create a new spool list level:

  • Choosing Execute + Print on the selection screen
  • Executing a program in a background job
  • Executing the statement NEW-PAGE PRINT ON. This statement, however, does not create a arbitrary stackable spool list level.
  • In a spool list level created with NEW-PAGE PRINT ON, no other spool list level can be created with NEW-PAGE PRINT ON. However, the other operations for creating spool list levels are still valid. If the addition NEW SECTION is used in NEW-PAGE PRINT ON, the existing request is used again or it is closed implicitly before a new one is opened.

  • In a spool list level not created with NEW-PAGE PRINT ON or while creating a screen list, no more than one spool list level can be created using NEW-PAGE PRINT ON.

A spool list level created with NEW-PAGE PRINT ON can thus be stacked only on a spool list level that was not created with NEW-PAGE PRINT ON or stacked when a screen list was created.

Up to 20 spool list levels can be stacked.

Open Spool Requests

The first output statement within a spool list level opens a new spool request whose number is placed into system field sy-spono. If another spool request is already open, it remains open and is used again after the spool list level has been exited. In a spool list level that has been created by calling a dynpro sequence, the spool request inherits the spool parameters of the preceding spool request. In all other cases, the explicitly specified spool parameters apply.

Close Spool Requests

When leaving a spool list level that was not opened with NEW-PAGE PRINT ON, that is, at the end of the program or when leaving a dynpro sequence, the spool request associated with the spool list level is closed. If a spool request stacked on the spool list level with NEW-PAGE PRINT ON has not yet been closed using NEW-PAGE PRINT OFF, it is also closed. Subsequent output statements continue to write to the spool list of the previous spool request or to the current screen list.

The statement NEW-PAGE PRINT OFF closes only spool requests for which spooling was activated using NEW-PAGE PRINT ON. If after that no previous spool request is open, spooling is switched off again, that is, subsequent output statements continue to write to the screen list. If a previous spool request existed, spooling remains activated and the output is again written into its spool list. NEW-PAGE PRINT OFF is ignored by spool requests not opened using NEW-PAGE PRINT ON.

After a spool request is closed, the number of the closed spool request remains in system field sy-spono until an output statement writes to a spool list again. This may be a new spool list or the list of a previous spool request. If after closing a spool request a previous spool request exists, the number in sy-spono differs from the number of that request until another output into its spool list is performed.

Note

It is best always to close a spool request that was opened using NEW-PAGE PRINT ON explicitly using NEW-PAGE PRINT OFF, before it is closed implicitly at the end of the program or when leaving a dynpro sequence.

Lists, Spooling.
