I have been analysing Ntdll file system functions from the total ntdll function list.
First, I obtain the total function list from ntdlls export directory.
Next, I seperated the file management set from the total function list and tried hooking the entire file management set.
However, I miss to hook a function, which i dint know. Hence I could not catch an API which takes Path as an input and performing a directory management functionality.
Is there anywhere you find/Know related information having the complete set of file management functions in NTDLL.
Probably you should implement an File System Filter Drivers (see http://www.microsoft.com/whdc/driver/filterdrv/default.mspx) instead of hooking of all possible undocumented file management functions from ntdll.dll

One customer wants to access a SAP report via RFC.
Steps:
Third party application connects to SAP via RFC
RFC call gets transmitted
SAP runs the report
SAP returns the report.
How can this be implement the part inside SAP?
I am using PyRFC as client library. But AFAIK this does not matter at all for this question. This question is only about the server part inside SAP.
In this case it is the report RM07MLBS which should be made available via RFC.
You need an ABAPer to make a function to you, I think there's no way without it.
If you have a ABAPer just do something like this:
SUBMIT <REPORT_NAME> ... EXPORTING LIST TO MEMORY AND RETURN.
CALL FUNCTION 'LIST_FROM_MEMORY'
TABLES
listobject = t_listobj.
CALL FUNCTION 'LIST_TO_ASCI'
TABLES
listasci = t_ascilist
listobject = t_listobj.
Now you have the list in ASCII format, you can convert it to what you want.
Another way is send the report result to spool, get the spool and convert it to HTML/PDF.
To convert Spool you can use this functions:
RSPO_RETURN_ABAP_SPOOLJOB
RSPO_RETURN_SPOOLJOB_DAT
RSPO_RETURN_SPOOLJOB_HTML
In a perfect world, you'd have the report logic encapsulated in an abap class or a dedicated function module and use that as the basis for both your report and the RFC calls. But if this is a standard SAP report and SAP themselves weren't nice enough to provide said function module, you may not have this option.
I don't think this is the best solution for your request, but just to add another option to the ones already mentioned in other answers: the commercial product Theobald Xtract Universal can execute reports and return the results using several available destination types. Xtract is a windows service that offers connectivity to several target database types as well as a http based result stream. It isn't cheap though, and it essentially only can connect to SAP Netweaver based systems as its data source (at least S/4 is already supported). Target destinations have to be purchased extra, but at least not per system, only per destination type (Oracle, MySQL, MSSQL...).
https://theobald-software.com/en/xtract-universal/
Xtract Universal uses a number of customer function modules to execute the report in the target system, catch the output and return it, essentially as a wall of text. You'll have to parse that result yourself, you won't get a nice pre-parsed table with data in it.
Just to make sure there's no misunderstanding about a possible conflict of interest: I don't work for Theobald, but we are a paying customer and use Xtract for our own data extractions. It is very simple to use, can be executed in scripts, but as said, just does that one job.
As far as I know there is a limited possibility to trigger a report via a rfc-enabled function module. Otherwise try triggering a transaction (based on your report) via function module.

I dont think that you are able to respond the report result to your third party system.
From consulting perspective I would recommend running the report periodically, write results in a table, fetch data from table (from third party system) via RFC-enabled function module.
The best way to do this would be to wrap your report in a bespoke Function Module that is RFC Enabled, then give them access to run that RFC Function Module.
I'm currently working on a project were am at the stage of figuring out what the current implementation is doing. Have been putting in a lot of time (A LOT) searching connections between queues declared as global variables.
Is there a way to get a listing of were a specific global variable is being used, or do I actually need to go through all processes, as I´m doing atm?
Thank you :)
in Tibco Designer 5.8 you can find where global variable is used using "Tools->Find Global Variable usages" menu item.
Please note that all tibco processes source code are text files. So, you also can search inside project folder using file text search from any utility that allowing you to search inside text files. For windows I prefer Far Manager
In the "Far manager" you can navigate to project folder then ALt+F7 and search for
%%GLOBAL_VARIABLE_NAME%%
Please also note that even if you don't have tibco project source code you can get it from tibco BW server. example path
tibco\tra\domain\tibco\datafiles\YOUR_PROJECT_NAME
Is there any function module aside from GUI_DOWNLOAD to download the ABAP report output?
When you say "ABAP report output", I am guessing you mean the list output.
You can use function module DOWNLOAD_LIST from within an ABAP report program to download the list, or any of the current lists in the stack.
Alternatively, use function module LIST_TO_ASCI to get the list into an internal table, then download it with CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD (GUI_DOWNLOAD will work, but it is recommended you use CL_GUI_FRONTEND_SERVICES instead). (Look at function group SLST for some other interesting list processing functions).
If you didn't mean the list output, then in general use CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD for downloading internal tables.
That is of course, if you are looking to download to the client PC. If you want to create a file on the application server, look at the keyword help for OPEN DATASET and related commands.
Can file operations, like creation of a file, be done in ABAP?
Yes it can be done.
You can code in ABAP by using 'open dataset' / 'transfer' / 'close dataset' statements to create files on the Application Server.
You can also create your file directly to a certain application for e.g. MS Excel like so.
Also there are several function modules and classes that can simplify certain tasks like gathering your report output, putting your file on the AS (such as 'GUI_UPLOAD' / 'GUI_DOWNLOAD' / 'WS_DOWNLOAD' / 'SAP_CONVERT_TO_CSV_FORMAT' / etc.) ...
Bear in mind that certain functions modules were built for foreground tasks so they won't work in background job scheduling ...
Yes, it's possible, as nict said before. You should start reading here - that's the official documentation, it covers pretty much everything, including working with files on both the application and the presentation server. It also explains how to use platform-independent filenames - always remember, someday you might encounter an application server running on OS/400 that will not let you write stuff to C:\Temp\MyExport.csv. One more hint: Be careful about the function modules nict mentioned, some of them are not safe to use when unicode content is involved. Always use the methods of class CL_GUI_FRONTEND_SERVICES to be on the safe side.
You can use CL_GUI_FRONTEND_SERVICES class or GUI_DOWNLOAD function. Here is a link
You may use CL_GUI_FRONTEND_SERVICES class. But this services only work on front end. Or you can use some function modules like GUI_DOWNLOAD, GUI_UPLOAD etc.
we can create a flat file with data entered into it, with tabs-separated.
Now, that dota corresponds to the sap tables-fields, where the tables are related to an application, like say, material master.
Now we can use the standard FMs to upload the data to the internal tables of the program and followed by updating the database.
So, uploading flat-file data can be done.
I am interested in creating a routine that would query the currently running cache processes and then write this information to a file. How could this be done in Cache 2008.2?
PERFMON might be what you're looking for. That's app with it's own UI, but you can call it's functions directly too, as an API.
Check the Cache docs for "Cache Monitoring Guide". That will give you links to PERFMON docs, as well as docs for other system monitoring tools.
You might find something useful in the Class Reference, under packages %SYSTEM, %SYS, and %Monitor.
For some process info you might need to shell out to the OS. In that case check into the $ZF function. That will let you invoke os-level commands from within Cache.
Oh, and you might want to consider saving the process data within the Cache DB, rather than dumping it out to a file. That is, create a Persistent Class with Properties corresponding to each process attribute that you want to capture, then write code to create, populate, and save instances of that class, taking the data from PERFMON or whatever other source you choose.
If you do that you can use Cache SQL to generate whatever kind of report you need. (Cache will automatically generate a SQL Table corresponding to your Persistent Class.) Cache supports ODBC, so you can use an external tool like Crystal Reports or Access for that part.
Obviously that will be more work than just echoing data to a file, but some kind of structure will be needed if you're going to do anything interesting with the information.
