Full up the missing value with zero value in dateset

[asch1234]

Hi, I have changed the dateset into montly frequency.

I want to full the missing value into zero.

For example, for ID=14593,

I like to obtatin the zero value from 2002M06 to 2018M05.

for ID=21020,

I like to obtain the zero value from 2002M06 to 2015M04.

I know I should use proc timesiries.

But, I can not figure out the problem.

Here is my code.

proc timeseries data=return
out =return1;
by ID day;
id month;
interval=month align=end format=MONTH. start="2002M06"Y end="Endday"M setmissing=0;

var RET;
run;

ID	day	Price	enday
14593	20160429	-0.00213	20180503
14593	20160531	-0.00116	20180503
14593	20160606	0.001148	20180503
21020	20140226	0.088704	20150412
21020	20140331	-0.03789	20150412
21020	20140430	0.111164	20150412

So what you've shown is what you have? Based on that, can you show what you expect as the output? Does your code run with errors? Can you include the log too?

This is the log file

LINE and COLUMN where the error has occurred.

And my other questions?

Is the data posted what you're starting out with? What do you expect as output?

Your code definitely has errors, for one it references variables not shown in your data set, such as RET, MONTH.

It is just a part of my dataset.

The log file show the error.

I like to obtain the data like this:

ID day Price

14593 201601 0
14593 201602 0
