You have two options really, if all three tables are using the same data set then combine them into 1 table (on different rows) and use an IF statement on the Tablix' Row Visibility Expression to only show row1 if parameters value equal ABC; only show row2 if parameter is BBC etc. Something like this: -
=IIF(Parameters!Test.value = 'ABC', FALSE,TRUE)
If there are using different data sets then you can put the above IF statement in each table and that should do it.
