Hello,
in the past, I had to manually insert data into an input module. Meanwhile, our anaplan models have been further developed and from now on I could automatise the line items of this input module with a formula by looking up this data in another model. But if I start adding a formula for this line item, I am going to overwrite all the data from the past. I don't want to do that. Are there any specific solutions for this? something with dates maybe (before this date and after the date? Some usefull help would be kind!
