What is the difference between Local and Global filter?

If you talk in terms of webI report, global filter is applied on report which is applicable to all the blocks present in the report, on the other hand local filter can be termed as filter on a particular block of the report.
All the filters/universe filters included in the report query are also considered as global filters.

What is the difference between Local and Global filter in Dex-I report.

Do you mean DeskI?
If you do, then the meaning is the same as Prashant postsed for WebI.

The answer remains same, gurus please correct me if I am wrong.

My understanding.
In Desk-I, the filter applied to the query is ‘query filter’. The filter applied to a block is ‘local filter’ and the filter applied to all blocks of a report at the report level is ‘global filter’.

My Understanding:
Block Filter: Scope is the block where the filter was created, other blocks on the same report tab are not affected, and other report tabs in the same document are not affected.
Report or Global Filter: Scope is the report tab where the filter was created. All blocks on that report tabs, even new blocks (if created) are affected, and other report tabs in the same document are not affected.
Query Filter: Scope is the document that contains the data provider. All blocks using data from the query are affected on all report tabs within the document. So in theory this could be called a document filter, but it’s really a query condition.
