Always post code and log using the "Insert [SAS] Code" functions -> running man icon! This is hardly readable mess.

The function is documented here. It seems that "30/act" is not a valid value for the third parameter.

Re: DATDIF function

Shrutibhatnagar — Wed, 20 Feb 2019 07:57:29 GMT

same error with 30/360 also .

Re: DATDIF function

Shrutibhatnagar — Wed, 20 Feb 2019 08:46:48 GMT

my answer is coming in negative values and it is saying that middle argument is invalid .

Re: DATDIF function

andreas_lds — Wed, 20 Feb 2019 08:53:04 GMT

Please check your data. Afaik the only invalid middle-argument (aka end-date) is a missing value.

Re: DATDIF function

Shrutibhatnagar — Wed, 20 Feb 2019 09:09:17 GMT

then how come it is giving an answer . the only problem is it gives a nagative integer with warning .

Re: DATDIF function

andreas_lds — Wed, 20 Feb 2019 09:13:07 GMT

Please post the log of your last run and show data.

RW9 — Wed, 20 Feb 2019 09:20:03 GMT

Post example test data in the form of a datastep:
https://communities.sas.com/t5/SAS-Communities-Library/How-to-create-a-data-step-version-of-your-data-AKA-generate/ta-p/258712

We cannot solve data issues without seeing the data!

From the log:

couponexpiry=20FEB2014

That looks like text, when you compare it to the other 'date' in your code:

day2=19996

Both values have to be valid dates.

Re: DATDIF function

Shrutibhatnagar — Wed, 20 Feb 2019 09:34:12 GMT

log and data are as follows

Re: DATDIF function

andreas_lds — Wed, 20 Feb 2019 09:39:47 GMT

Sorry, but screenshots and Excel-files are of no use. See the message of @RW9, it explains how to post data in usable form.

Re: DATDIF function

VDD — Sun, 17 Mar 2019 15:24:38 GMT

It may be that you don't have real SAS dates or that you have incorrectly used the datdif function.

data _null;
	mydate=DATDIF(19996,19779,'30/act');
	put mydate;
	mydate=datdif('01JUN1996'd,'01SEP1977'd,30/act);
	put mydate;

run;

It is hard to tell with so much noise from the code. Make a simple test dataset and get the logic to work then add back into that code all the extra stuff.
