Observations does not show

[mayasak]

Hi, 

I'm trying to combine two datasets, two from the prelimenary network drive (P) and one from the final network drive (Q, the backend server drive).

I prepared and cleaned the 2 datasets from P and merged them with the Q data set (which was not touched) then I saved the merged set in the P drive. What happened is that all the datasets related to the merged data set do not show up (I mean the data observations, only variables show up) when I opened them in SAS. But when I tried to read them in SAS, all proc contents, proq freqs work, also all the queries still work perfectly on the related website. This means the data is still there but it doesn't show up. Yesterday, I had the same problem and I'm not sure what I did and it showed the obseravations back. Today when I was still manipulating the data and saved  the merged data set I had the same problem again. I have no clue on what's happening, I concatenated two other datasets before and didn't have any problem, could it be the merging the datasets and if that is the case, how should I solve it.

Thank you.

It's hard to say without seeing your code. My best guess is you are not viewing what you think you are viewing (perhaps a local data set rather than a permanent one?). I suggest using Proc Datasets to delete any local data once you are done with it, and see if that clears up the problem.

Thank you  for your reply, here's the code I used.

I've already deleted the merge dataset file that was saved from the P drive and not by using SAS code. Yesterday like I said I had the same problem but it suddenly worked (don't have any clue how) and today I had the problem again.

(FYI by not seeing the data, I mean when I double click on it from the P or Q drive; the proc print works just fine)

[EastwoodDC]

I don't see anything in the code that would cause what you describe.

In the last data step though:

merge brfss1 brfss5;

Is brfss5 what you mean to merge, or should it be brfss6?

This might cause unexpected results if same-name variables in brfss1 are overwritten.

[mayasak]

The variable names are different though.

So the data sets are there but seems to have no observations?
What does proc contents tell you?
What SAS client are you using?

[mayasak]

Thank you LinusH. Yes the data sets are there and every thing seems fine but the tmp data ( when I just click on the data file from the P and Q driver) shows only the variable row and no observations. Proc contents, proc print, and proc freq all are working fine. Attached is the proc content.

And as I said yesterday I had the same problem but it worked at some point (I was deleting all dat sets that I saved recently on driver P when data showed again on both drives P and Q; I have no clue how and why) . Today I had the same problem again after I was manipulating, merging and saving the merged dataset on P.  I deleted the new file but still have no data there.

What SAS client / user interface are you using, and version?

[mayasak]

SAS 9.4 version, I'm not sure about SAS client.
