Hi Prasad,
The word comment is used in different scenarios within QlikView,
Comment Field/Table :
Provides a way of displaying the field/Table comments (metadata) from databases and spreadsheets. Field/Table names not present in the document will be ignored. If multiple occurrences of a field/Table name are found, the last value is used.
The keyword can be used to read comments from a data source using the following syntax:
comment *fieldlist using mapname
comment tables tablelist using mapname
Notes and comments :
Notes and comments can be added to all objects when connected to a QlikView server, allowing users to create and share notes about the current object.
Notes are shared with other QlikView users, and these users can respond by leaving their own comments. It is also possible to save a snapshot (bookmark) of the data with each note.
When right-clicking an object, it is possible to add a new note and to view existing notes, by selecting Notes from the context menu. After having selected Add a New Note or View Attached Notes, all objects in the current document with existing notes are supplied with an indication in the top left corner. The number of attached notes for each object is displayed in the indication.
comment script line:
You can right click on any Qlikview code and comment it from being executed. This is like a REM statement in SQL
