Hi @Markus Freitag ,
The method you mentioned is indeed a good idea.
It does work when the amount of data is small. When the amount of data is large, you may need to define many reference variables. We should avoid this situation.
When there is a lot of data, you could first use the contains() to confirm whether the key you want to change exists in the map, and the value of the map can be changed by
m2["abc"] = "change to 20221019 - 0127";.
