SAS Pipe gives error in batch after uncertain time period

[SirRolin]

Hi, I have had some mysterious behaviours in SAS,
I have 4 different SAS Codes, that is getting used in a batch run,
Each of them use the same pipe code, but the 3rd and 4th Pipes fail.
I have tried to Clear the name after I am done with the pipes, didn't help.
I tried to make different names for all the pipes, didn't help.
but it is only when run in batch that they fail, if I run them manually they do work. all of them.
Here's the Pipe.
filename FlistCB4 pipe "dir /s/b/a-d ""I:\Dat\4841CPM\28 Kredit\15 Green Loans\*.xlsx""";

Hi and welcome to the communities!

Please post the whole log of such a failed call to the pipe (including the FILENAME statement and the data/procedure step where the file reference is used).

Sorry for the long wait.
Here's the Log:

NOTE: The infile FLISTCB4 is:

      PROCESS=dir /s/b/a-d "I:\Dat\4841CPM\28 Kredit\15 Green Loans\*.xlsx",
      RECFM=V,LRECL=500

Stderr output:
Invalid Signature.
NOTE: 0 records were read from the infile FLISTCB4.
NOTE: The data set WORK.FLISTIOME has 0 observations and 7 variables.

[Kurt_Bremser]

The "Invalid Signature" is a Windows response connected to a problem in the SMB protocol. It usually happens when connecting to older NAS boxes that do not support a certain security feature introduced with Windows Server 2012. A Google search for "windows dir invalid signature" will reveal more.

@SirRolin If it's a samba authentication issue, you need be fix that.

On the other hand, maybe this issue will not be triggered if you don't use a pipe.

Try listing the files using another logic such as this one: https://communities.sas.com/t5/SAS-Programming/listing-all-files-within-a-levelectory-and-sublevelec...

Sorry for the huge delay, had lots going on.
Finally got around to test this, and it worked perfectly. Thx

Is the content of the pipe expected to change between uses? If not then I would suggest a method to capture the result one time (the first??) and place the result in a data set in a library that all of the code can access.

[SirRolin]

yes it's supposed to change.
