I need to get a listing of a server-side directory inside SAP. How do I achieve this in ABAP? Are there any built-in SAP functions I can call?
Ideally I want a function which I can pass a path as input, and which will return a list of filenames in an internal table.
EPS2_GET_DIRECTORY_LISTING does the same thing as EPS_GET_DIRECTORY_LISTING BUT retunrs the file names up to 200 chars!
Call function RZL_READ_DIR_LOCAL:
FUNCTION RZL_READ_DIR_LOCAL.
*"----------------------------------------------------------------------
*"Lokale Schnittstelle:
*" IMPORTING
*" NAME LIKE SALFILE-LONGNAME
*" TABLES
*" FILE_TBL STRUCTURE SALFLDIR
*" EXCEPTIONS
*" ARGUMENT_ERROR
*" NOT_FOUND
*"----------------------------------------------------------------------
Place the path in the NAME import parameter, and then read the directory listing from FILE_TBL after it returns.
RZL_READ_DIR_LOCAL can handle normal local paths as well as UNC paths.
The only downside is it only gives you access to the first 32 chars of each filename. However, you can easily create a new function based on the RZL_READ_DIR_LOCAL code, and change the way the C program output is read, as the first 187 characters of each filename are actually available.
After reading the answers of Chris Carrthers and tomdemuyt I would say:
1) Use RZL_READ_DIR_LOCAL if you need simple list of filenames.
2) EPS_GET_DIRECTORY_LISTING is more powerfull - it can also list subdirectories.
Thanks You both!

the answer is calling function module EPS_GET_DIRECTORY_LISTING.
DIR_NAME -> Name of directory
FILE_MASK -> Pass '*' to get all files.
Note: This does not deal with really large file names (80 characters+), it truncates the name.
Take a look at transaction AL11 source code: RSWATCH0 form fill_file_list
There you can get all information about files.
Hope this helps!

I have an SFTP directory that contains several files in this format
19328D_T001045863113302101909_20220721_103898.txt
1932A8_T001045863113302101909_20220721_103802.txt
The part starting with T i have saved as a dynamic variable vars.transaction (e.g. vars.transaction == "T001045863113302101909"). I want to do a check if I have any files in this directory that contain my vars.transaction in the filename.
So I think I need to use sftp list connector, edit inline and use filename pattern. But as there is numbers before and after the Transaction part I am not sure what to put in the filename pattern. Something like [#vars.transaction]
Thanks in advance
You can use the wildcard * along with your variable. Like *#[vars.transaction]* that will match all the files which has the vars.transaction in their name
We are trying to read file from directory based on pattern from azure blob srorage.We are using
pathGlobFilter option to select files. The directory contains following files
Sales_51820_14529409_T_7a3cc7d1d17261fd17e7e1fabd3.csv
Sales_51820_14529409_7a3cc7d1d17261fd17e7e1fabd3.csv
Sales_61820_17529409_7a3cc7d1d17261fd17e7e1fabd3.csv
Sales_61820_17529409_T_7a3cc7d1d17261fd17e7e1fabd3.csv
We need to process only those files which does not have "T" in file name .We need to process only these two files
Sales_51820_14529409_7a3cc7d1d17261fd17e7e1fabd3.csv
Sales_61820_17529409_7a3cc7d1d17261fd17e7e1fabd3.csv
But we are not able to read only these two files.
Here is the code,
df = spark.read.format("csv").schema(structSchema).options(header=False,inferSchema=True,sep='|',pathGlobFilter= "Sales_\d{5} _ \d{8}_[a-z0-9]+.csv$").load("wasbs://abc#xxxxx.blob.core.windows.net/abc/2022/02/11/"

Glob is not a standard regular expression, there is differences between them.
For example glob doesn't match the number of times.
For details, see:here
Back to this question, a relatively stupid way, looking forward to the perfect solution of the giant.
pathGlobFilter="Sales_[0-9][0-9][0-9][0-9][0-9]_[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]_[a-z0-9]*.csv"
When using Snakemake, I store the values for my variables as part of the filenames (ex. "processed/count_{project}.tsv"). Recently, I've started using R formulas with many covariates as a variable. Now I get an error because the the filename is too long for the operating system. Has anyone else run into this issue and have any suggestions? Is there a canonical Snakemake approach for this problem?
Personally, I don't think it is a good idea to store information into the filename.
Rather, I would create a temp file in tabular or yaml format linking the file in question to covariates or other data. Then read this file in R or else to extract the relevant information.
One idea is to use paths instead since paths allowed to be longer.
I thought for sure there would be an SO question on this, but I haven't been able to find one.
I have 2 SQL files, myFile1.sql and myFile2.sql. myFile1.sql calls myFile2.sql like so:
-- In myFile1.sql:
#scripts/myFile2
This works with no problem, but now I'd like to pass an argument to the file. I've tried doing the following, with no success (results in a File Not Found exception):
#scripts/myFile2 'ImAnArgument'
Does anyone know what the syntax would be to do this?
I'm guessing your problem is that scripts/myFile2.sql is a relative path from the script it is located in. If that is so, then it is following that path from the directory where SQL*Plus was started (the current working directory). If this is the problem, then it's not the parameter that is the issue, but rather that SQL*Plus can't find the file. In this case, you should use ##, which invokes the path relative to the file it's located in.
The parameter should work just as you proposed (documentation). Parameters provided when invoking a file are placed into substitution variables (rather than bind variables) and can be referenced by using an ampersand followed by the argument number. In your example, 'ImAnArgument' would be &1.
After many attempts, I wasn't able to pass a parameter in (and I still don't understand why not). But here is what I did to get the same affect:
-- In myFile1.sql:
DEFINE my_arg = 'ImAnArgument';
#scripts/myFile2
Then
-- In myFile2.sql
-- Do stuff using the variable my_arg, such as
SELECT my_arg FROM my_table;
By default AutoCAD installs a text based file called acad2010.lsp at the set location below
Dim FILE_NAME As String = "C:\Program Files\AutoCAD 2010\Support\acad2010.lsp"
However it my be that the user/ administrator/ or third party has changed the location of this file. Is it possible to then locate it using the following
Dim FILE_NAME As String = "C:\*\acad2010.lsp"
In other words search the entire c:\ drive for file acad2010.lsp?
If this doesn't work can you please let me know what would?
You could search for it with an FSO. It's not going to be fast however you do it but this is the fastest way I can think of.
http://www.microbion.co.uk/developers/fso.htm should give you a rough idea of how it's done.
Your solution will not work. Is not possible to locate it using *. (BTW is possible in ms-builds scripts). The only way of doing it is:
1- Create a FindFile function (check for example
http://xlvba.3.forumer.com/index.php?showtopic=125)
2- Use it to locate the exact path of the file. (It could be really time
consuming)
3- From this point your code is the same...
Unfortunately, you can't use wildcards in a filepath. You have two options:
Prompt the user for the file location using the "Open File" dialog. The code to do this varies based on which Office product you are using. In Excel, you would use the Application.FindFile method (more info here).
Write your own function to search the filesystem for the file. Microsoft provides an example here.
If that file is used by internal functions of the application, the installer will have recorded a registry key for the file's location.
Open regedit.exe and search for the file name and path.
You can read a registry entry using this VBA one-liner:
CreateObject("WScript.Shell").RegRead(strRegPath)
You may need a terminating backslash on the key address, but that's a safe and simple registry access method. More details on the MSDN site:
