Hi,
I need to split the record based on a group of date ranges.
In picture 2 ATRT='TENOFOVIR ALAFENAMIDE (TAF)' record ASTDT and AENDT dates fall into two phases from picture 1 ,
so i need to make new records as in picture 3.
Picture 1
Picture 2
Picture 3
please let me know ho to do it.
Thank you,
Raja.
Please provide data as working SAS data step code, as you did in a previous thread.
Hi,
Below is the CSV data;
Picture1 data:
USUBJID,APHASE1,APHASE2,APHASE3,APHASE4,PH1SDT,PH1EDT,PH2SDT,PH2EDT,PH3SDT,PH3EDT,PH4SDT,PH4EDT

Picture2 data:
USUBJID,EXLNKID,AOCCUR,ATRT,ADOSE,ASTDT,AENDT,AVISITN,APHASE,APHASEN
73763989HPB2003-100004,NA-20211102T1040,Y,TENOFOVIR ALAFENAMIDE (TAF),25,02NOV2021,16FEB2023,28,Open-label,2

We need data as SAS data step code, as in the other thread you wrote that I linked to.
Hi ,
Please let me know how i can create sas code with data values by using
CSV file data.
Thank you,
Raja.
You already have the data in SAS, I know this because you showed us screen captures of data in SAS. You work from the SAS data set, not from a CSV file. Here are examples of what SAS data step code looks like and instructions on how to create such code.
Hi,
Thank you for code.
Here is the data.

Ok, very good. But now I don't understand the logic, how do you know that the ASTDT = 02NOV2021 and AENDT=16FEB2023 in picture 2 is split in the output into two rows with the dates shown, one row being 02NOV2021 to 21MAR2022 and the next row being 22MAR2022 to 16FEB2023?

You really need to make sure that your question makes some sense in terms of provided "data". You picuter 1 does not show any variable named ASTDT or AENDT. So there is no way we can interpret that request clearly. You actually don't even mention how Picture 1 comes into the process at all.
Provide rules, not pictures. Computers run on rules and without a clearly defined set of rules on how to do something then a proposed solution that works ONLY for the shown data maybe provided but would not work for more of a caste.
