I am trying to detect data errors that occur outside the accptable range. I have 193 variables. I want to keep the ID, Obs, Var(one specifiec var - not all 193) to 193 datasets. Then set them into one.... How whould I apply each cirterial to the apporopirate variable and get it all the erros back into one dataset? Thank you.

Data Errors;

set coverbtch;

where p0001 not in (.,1,2,3,4,5,6,7); keep id obx p0001;

For starters the number of unique error checks is a lot less than 193. For example the check not in (.,1,2) is applied to over 20 variables but can be considered just one check. I suggest you dedup your checks down do a unique list, then figure out which variables they apply to.

For doing one check on multiple variables an array is the way to go. I would also create a binary flag for each check also using an array. Here is a simple example for the not in (.,1,2) check:

```
data want;
set have;
array pvars (*) p0001 - p0193;
array checks (*) check1 - check193;
do i = 65, 66, 69, 74, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86;
checks(i) = (pvars(i) not in (.,1,2));
end;
if sum(of check1 - check193) > 0;
run;
```

Thank you SA Skiwi. I have revised the code to use if statements. Im not understanding the array... I can look into it... Where there are multiple errors per ID, can the array create multiple flags per ID? The way this is written, there is only one output for one error per ID.

Data Errors;

set coverbtch;

if p0001 notin (.,1,2,3,4,5,6,7) then do; Flag='p0001'; pval=p0001; end;

if p0002 notin (.,1,2) then do; Flag='p0002'; pval=p0002; end;

if p0003 notin (.) and p0003>40 then do; Flag='p0003'; pval=p0003; end;

if p0004 notin (.) and (p0004<2005 or p0004>2015) then do; Flag='p0004'; pval=p0004; end;

if p0005 notin (.) and p0005>3000 then do; Flag='p0005'; pval=p0005; end;

if p0006 notin &countylist then do; Flag='p0006'; pval=p0006; end;

if p0007 notin (.,1,2,3,4,5,6,7,8,9,10,11,12,13) then do; Flag='p0007'; pval=p0007; end;

if p0008 notin (.) and p0008>999 then do; Flag='p0008'; pval=p0008; end;

The simplest answer is that you would never do this. Consider what you would end up with. Your final data set after putting the 193 data sets together again would contain all the variables. But it would contain fewer observations ... those with something out of range. And the variable values would change: anything that was originally in range would now contain a missing value. All of that can be accomplished in a single DATA step, without creating 193 separate data sets along the way. For example:

if p0003 > 40 then p0003 = .;

Then at the end, something like:

]

if n(of p0001 - p0193) = 0;

When I say "something like" it's because I can't tell whether COUNTY is numeric or character. And I can't tell whether there are other numeri variables (not being checked) that need to be accounted for when selecting.

First, you will need to fix many of your checks. They are not all valid SAS code. And you will need to consider whether a missing value is going to be considered something that needs to be checked. Some of your checks flag missing values. But the general objective should be to create one data set, without separating into 193 data sets.

Hi:

And, in addition to all the other good suggestions you've received, I'd like to point out that stringing your WHERE statements like that is not a good practice, as shown below. Did you notice the messages in the log about the WHERE clause being replaced???

Is the purpose of this exercise to varify that values are within expected ranges for the variables?

If that is the case you may want to consider going back to where your read in the data and use custom informats that check the valid ranges. I use this for several projects to check the data before going on to the next steps. If your "error" rate is low this may be viable solution.

If you want a record of the log results use Proc Printto to create file of all of the error messages.

proc format library=work; invalue p0001in .,1,2,3,4,5,6,7 = _same_ other = _error_; run; data example; informat id best5. p0001 p0001in.; input id p0001; datalines; 1 . 2 1 3 2 4 3 5 4 6 5 7 6 8 7 9 0 10 1.5 11 444 ; run;

which generates a log like:

55 data example; 56 informat id best5. p0001 p0001in.; 57 input id p0001; 58 datalines; NOTE: Invalid data for p0001 in line 67 3-3. RULE: ----+----1----+----2----+----3----+----4----+----5----+----6----+----7----+----8----+-- 67 9 0 id=9 p0001=. _ERROR_=1 _N_=9 NOTE: Invalid data for p0001 in line 68 4-6. 68 10 1.5 id=10 p0001=. _ERROR_=1 _N_=10 NOTE: Invalid data for p0001 in line 69 4-6. 69 11 444 id=11 p0001=. _ERROR_=1 _N_=11 NOTE: The data set USER.EXAMPLE has 11 observations and 2 variables. NOTE: DATA statement used (Total process time): real time 0.03 seconds cpu time 0.00 seconds

The informat approach has a couple of advantages:

1) variable with identical data limits can share the same informat

2) the resulting data set will not have any erroneous values (except missing if that is an error)

3) records with multiple errors will all be together in the log. If I had 100+ variables and variable p0001 and p0100 had errors

the log would show something like:

NOTE: Invalid data for p0001 in line 68 4-6. Invalid data for p0100 in line 68 245-247

so I wouldn't be looking all over for where multiple errors occur on the same line.

4) sometimes this yields enough information that you find out the file format is not as expected

Ranges in Proc format can be done with

20 - 40 =

or

0 < 1, 50>high

The Errors are printed by Batch#, pval, and ID/Obs then given to someone to open the key entry-text datafile, find the error, correct it and save.

The above does show the P variable and line number in the file. Id will be one of the many variables with a value in the diagnostics. This can produce a lot of text if you have errors on many rows.

You did not mention "batch#" or show how that would be know in your first post. So I'm not sure how to include that information.
