hi all,
what is the difference between join and applymap ?
both serve the similar purpose..
In applymap.. you can replace a matching value in one field only..
but in case of join based on machining condition you can add multiple fields..
for more descriptive difference better to use QlikView help or reference manual.

Hi,
1.First and main difference when ever apply map is used then in map table we have maximum two fields required.
2.But in join this condition not apply, in the join when two table is used more than fields in a table can join but in one of the table unique keys is required for perfect join.

The reason I have used applymap a lot is (as opposed to join)
The disadvantage are
thank you
Hi,
We can use Joins to combine/concatenate multiple records, there won't be any condition.
but in apply map the mapping table should contain only two fields and we can combine only one field. another field should be common field.
