How to pass dashboard data to BIWS (throgu prompts)to inplement MATCHES PATTERN(like) functionality

dashboard data is coming from Webi report using BIWS.

here 2 tables are used 1. ENTITY(entity_name,viewname,entity_note,entity_def),, 2. ATTRIBUTE(Attr_enti_name,Attr_name,Attr_def,Attr_note,datatype,PKey)

in part1

1.search string is entered from dashboard in part1

2.based on input from part1, table names will be listed in part2

3. when we select a table in part2, part3 data is populated.

here,

part2 tables names(from entity table) are need to be selected based on follwing Conditions(SQL)

entity_name like '%inputstring%'

entity_note like '%inputstring%'

entity_def like '%inputstring%'

Attr_name like '%inputstring%'

Attr_def like '%inputstring%'

Attr_note like '%inputstring%'

Here as the webi report data is scheduled one, which is used by biws for dashboard, this 'like' functionality is not working when binding above prompts(used in webi report query) to input string from dashboard.

So how can i get this  like functinality to work here
