What is 'date range' in SAP CRM?

Question

I am SAP CRM beginner. Also very new to SDN. Reading very basic documents.
While reading Marketing related document (Campaign Management), I have come accross a term called ' date range ' where I am really confused with -
what is - date range, pre-dip- post-dip, buying period........
& what is the use of the same.

Answer 1

hi
date range specifies that in a particular transaction what is the validity of the transaction,for example LEAD<ACTIVITY etc are the transactions we have in CRM
as u said you saw it in campaing management,there date reange specifies the start date and end date opf the campaign
whenever we start a acmapaing after executing it we have some start date from where we got to see the results of the campaign,
you define an additional date range that has a specific meaning, for example, pre-dip or post-dip, you need to select the corresponding period type in this activity. This is used to trigger validation of the dates in the BW System.
You should define at least one buying pattern type in Customizing for Marketing Planning and Campaign Management under Basic Data -> Define Default Buying Pattern Types.
For Instance  you can define that the buying period should start weeks before the promotion takes
place and that buying finishes weeks before the end of the promotion. You define the buying period
as a date range in Customizing and then you can enter the actual dates here. A buying pattern can
be defined for each combination of campaign type, buying pattern type and duration.
also technically if u know about date range in CRM
i would like to explain like this that
there is a thing "milestone"
this refers to the range of date from start to end
withinthe particular date that you mention inside the transaction u do the needed task like u create a new task and u do the buying and u generate invoice
in simple terminology we have date range which specifies the start of a particular task and there is always an end date at which this task has to end,so take this way
check out the date range in trade promotion (trade promotion is an alternate for the campaing in CRM)
