Worklists
Definition
A summary of objects which meet certain criteria and require further processing.
Use
You can use work lists to list all the documents that still need processing with a certain subsequent function. This can be purely for information purposes. Or you can use it to process the documents more efficiently.
Structure
Once you have entered your selection criteria, the system displays a list that you can edit with the
ABAP List Viewer. 
Not all functions in the ABAP List viewer are available for some of the work lists.
From this list, you can start the subsequent functions for some or all of the documents at once.
Call
You can call up worklists either using the appropriate application menu or using the central reporting tree.
