I want to create multiple rows based on time interval between two variables. I've the data as below. We have 'Duration' value as 3 for each 'Year_mo' (2017-03 and 2017-06) in the data below.
Branch Segment Type Year_mo Start_Mo End_Mo Duration 71831234 7183_AS4 Cdir 2017-03 2017-03 2017-09 3 71831234 7183_AS4 Cdir 2017-06 2017-03 2017-09 3
Now I want to create as many as rows based on the value from the variable 'Duration' and I've to create one more variable called 'Cal_Month' which should have values in quarters between time interval of the variables 'Start_Mo' and 'End_Mo
with group by 'Year_mo'
In this case values of 'Cal_Month' should be in 2017-03, 2017-06 and 2017-09. 'Duration' value is 3 for each each 'Year_mo'. So I need 3 observations for 'Year_mo' with the respective 'Cal_Month' values.
Desired Result is,
Branch Segment Type Year_mo Start_Mo End_Mo Cal_Month 71831234 7183_AS4 Cdir 2017-03 2017-03 2017-09 2017-03 71831234 7183_AS4 Cdir 2017-03 2017-03 2017-09 2017-06 71831234 7183_AS4 Cdir 2017-03 2017-03 2017-09 2017-09 71831234 7183_AS4 Cdir 2017-06 2017-03 2017-09 2017-03 71831234 7183_AS4 Cdir 2017-06 2017-03 2017-09 2017-06 71831234 7183_AS4 Cdir 2017-06 2017-03 2017-09 2017-09
In real life I've data with 'Duration' from 1 to 9 and "Year_Mo' is also I have multiple Dates. To get the idea to tackle this Scenario, I just shared the sample data here.
This duplicates your wanted data given the starting data.
data have; input Branch $ Segment $ Type $ Year_mo :anydtdte7. Start_Mo :anydtdte7. End_Mo :anydtdte7. Duration; format year_mo start_mo end_mo yymmd7.; datalines; 71831234 7183_AS4 Cdir 2017-03 2017-03 2017-09 3 71831234 7183_AS4 Cdir 2017-06 2017-03 2017-09 3 ; data want; set have; cal_month=start_mo; do until (cal_month > end_mo); output; cal_month=intnx('month',cal_month,duration); end; format cal_month yymmd7.; run;
You may run into interesting output if your duration value does not divide nicely in the number of months between start and end months.
Please note that I provide a way to create actual data for testing code in the form of a data step. That is the preferred manner of providing example data as then there is no need to ask questions about data types.

First, are all of your year_mo start_mo and end_mo variables actual SAS date values, i.e. numeric with an apparent format of YYMMD7.?
Yes, all the variables (year_mo start_mo and end_mo) are SAS date values. I'm looking for logic to fit this requirement via SAS program.
