Distinguishing actually date in lots of missing values

[iksawffej]

HI, 

I'm currently bothered by a task. 

For the following dataset containing ID and birthday to confirm unique information for each subject. I have to check the actually first bleeding date for each patient, which was defined by

1) bleedingday-14<= gastroscopyday <=bleedingday+14 and

2) bleedingday<=gidrugday<=bleedingday+30.

For instance, the first bleeding date of ID 7000XXXXX should be recognized as Day 15292. 

Can anyone give me some hints to work on or any codes to fix it?

thanks!

Please post your data in reusable form. The following link contains a macro that will do it for you: https://blogs.sas.com/content/sastraining/2016/03/11/jedi-sas-tricks-data-to-data-step-macro/

Also, please ensure that any identifying information is not posted. If you need to create a pseudo ID, please do so beforehand. Someone recently posted identifying information on another post, so double-check before you post. Thanks.

Hi, thanks for your remind, the reusable example has been posted.

I don't understand the desired output, can you explain further and actually show us a small portion of the desired output?

Also, we can't write code to work on data in screen captures. Please provide the code according to these instructions https://blogs.sas.com/content/sastraining/2016/03/11/jedi-sas-tricks-data-to-data-step-macro/ and not as a file attachment or screen capture.

The final output contains  ID birthday and the correct bleeding date matched the criteria above will be good.
