RFC function and SAP logon window

Hi experts,
i created the report which uses RFC function ( returns some info from dev. system ). Long time it worked without problem, but before several days ( maybe SAP basis did some changes ), when i run the report and is called RFC function, system ask me to log on into the system.
Do you have any idea ?
Thanks in advance

Error found in RFC (target) and respective logon\logons are disabled.

Hi All,
So we have a requirement to use trusted connections for our EAM configuration and after setting up FFUser when the user login in to the system and execute GRAC_SPM we automatically get the message "Error found in RFC (Plugin System) and respective logon\logons are disabled." We saw note 1777094 that suggest to update validity and password of RFC user, but because this is a trusted connection there is no "RFC User" or in other words the user is the "Current user" of the session and note 1652880 is suggested as a possible fix for Non trusted RFC. Can anyone point me in the direction of what the issue is here?
we automatically get the message

Hi Santosh,
Our problem was a mixture of not understanding correctly RFC objects and also when to use trusted vs standard connections. As shown in this link http://help.sap.com/saphelp_nw70/helpdata/en/6b/af429b12e9214d9a2d6cba921b162f/content.htm auth objects related to RFC are actually not included on the SAP profile (that was one of our problems) so our configuration for S_RFC was incorrect. Also using trusted connections is not mandatory any more to use EAM so at the end using Standard connections was a better approach. Hope that helps.

PDF document not open and SAP logon closed by CV04N,

Hello,
When I try to open the PDF document by transaction CV03N/CV04N, it's crash the SAP login.
Please give anybody solution for this issue to fix
Thank
Surya

Hi Surya,
is it the same with CV03 as well?
Is it the same crash using Display Document WebUI? (if you have EhP5+)
You can uninstall your Adobe Reader from your computer and download the latest version from here:

AWS HANA ABAP and sap logon pad

I am looking to consume HANA views with ABAP (as demostrated here SAP HANA Academy - ABAP: How to consume HANA procedures in ABAP - YouTube )
I have an AWS account with a HANA installation running with which I have connected with HANA Studio (rev 80) successfully.
The SAP GUI 730 (Patch 4 Hotfix 2) is installed and I have also successfully installed Eclipse Kepler (in accordance with this guide Step-by-step Guide to setup ABAP on HANA with E... | SCN )
When I try to create an ABAP project I am asked to either use the connection details in the SAP logon pad or connect manually. I have not maintained the logon pad details and hence wish to connect manually.
Here is where it gets fuzzy to me. In order to connect with my HANA instance what do I enter as:
- Application server? The IP-address of the HANA instance, right?
- Instance number?
- System-Id?
- SAP router string?
I assume that this is all information that is available with my AWS instance, but I dont know where to find it. Furthermore, I am assuming that no additional components are required in my set-up. If this assumption is wrong please indicate what is missing.
I greatly appreciate any support.
Thanx

WebSAPConsole , telnet serever ,RF terminal and SAP logon screen

What would be the easiest way to connect RF terminal(character based) to an SAP system.
Of course it is via WebSAPconsole. As far as I red WebSAPconsole guide if I want to use it to connect character based RF terminal is the same as preaviously SAPconsole(under e.g.SAP enterprise 4.7 ext2.)
1.st install telnet server (best SLnet 2.6RF from Seattle LABS) and then configure In SAP console administrator in Control panel entered corresponding system ip,sysnr and transaction code(from saplogon)
However on RF terminal SAP logon screen does not appear. But only telnet prompt.
What to do? Should the telnet server and SAP console be on an other machine than SAP server(ECC6)?

Hi Thomas Kremer,
Can you help me to solve this issue!?
I´m facing with same error then you. I did a homogenous system copy and after I finish this SAPINST I install the saplogon and of course I try to accede to SAP system and the first thing that display in system is that short dump --> dynpro_itab_error
What´s this?! How you solve this issue... can you remmember? (I know that already was a two years ago but even so if you remember this can you share with me!?).

RFC function is called with null paremeters on SAP side

I used the new version of .Net Connector 2.0.1.
I created a simple client called RFC function with one table parameter and simple RFC function inserts record to simple table on SAP side.
If I call this RFC function from SAP side the record is inserted to my table with correct value.
If I call this RFC function from NET side the record is inserted with null value.
What's wrong ?
Could anybody help me ?
Code :
SAP side
FUNCTION ZRVFRFCNV.
*" TABLES
*" ITDATA STRUCTURE ZRVNAMEVALUE
insert into ZRVNAMEVALUE values ITDATA.
ENDFUNCTION.
Net side
ZRVNAMEVALUE nam_val2 = new ZRVNAMEVALUE();
nam_val2.Name = "100";
nam_val2.Value = "NORD";
ZRVNAMEVALUETable tblTest = new ZRVNAMEVALUETable();
tblTest.Add(nam_val2);
// for testing : dataGrid show correct values
dataGrid1.SetDataBinding(tblTest, "");
this.sapProxy11.Zrvfrfcnv(ref tblTest);

The problem was in insert statement. I changed insert to modify on SAP side and solved it.

SAP GUI with SNC logon and Hummingbird Exceed - SAP GUI window size issue

We have discovered an issue when SAP GUI 7.10 is used to logon via SNC and Hummingbird Exceed is used on the same workstation to logon to a UNIX system either via x-windows or telnet.
When the user logs onto a UNIX system using Hummingbird Exceed, then uses SAP GUI to logon to a SAP system with SNC authentication, the SAP GUI authentication works, but the favourites list is not fully displayed and has to be resized before any of the entries are available.
Has anybody else seen this issue, and do they know if there is a fix available ? We wondered if there might be an issue with fonts or some other sort of conflict between Exceed and SAP GUI, but it is strange that the problem only occurs if SNC authentication is being used, and when userid+password is used to logon to SAP the problem does not occur.
Cheers,
Tim

Hello Tim and Wolfgang,
I was curious too as I found it interesting... so I tested a few combinations, but could not reproduce what Tim has described, at least not before my CPU reached 100% and the applications stopped responding (~2GHz processor, 1GB RAM, 48 kbps connection, latency ~ 2 x width of the Pacific Ocean, but Backend 7.00!).
However I did notice some indications which might be a help (based on 7.00!):
Back in 4.?? there was a problem in that large menus could not be searched(!). Sorry, I don't have access to SAP now, but from memory the note # was 444043 (or very similar) and introduced a form routine for large menus - from a printscreen I still have the message number which led me to the note - 'I476(S#)'.
The system certainly distinguishes between MENU_TYPEs and the above note corrections could be found in several locations relating to the SAP menu 'S', the role menu 'A' etc, but I could only see that for favourites 'F' this is implemented for the menu search (when searching, not when loading).
@ Tim: Ask you customer to create a favourites menu which only has 1 node or max 2 (certainly not more than 4!) and ~ 20 executable objects in it (not more than 30!)? Can they under any conditions achieve the described problem with such a menu?
If not possible to reproduce, then the closest I could guess is a maximum limit of 4 nodes and max 30 objects for a 'F'avourite menu, before it is a minimum candidate for "performance problems" and consideration to be converted to a role ('A'ctivity group) menu instead.
Sorry that I can only help by speculating, because I could not reproduce what you have described.
Hopefully this problem will not happen to me in the New Year, and hope you will solve it for the rest of the year
Cheers,
Julius

How to create RFC function module and how to call this function module

Hi,
i want to know step for creating RFC function module and then How to use this function module from some other sap system.
Thnaks,
jigar

Jigar,
To implement a remote function module in ABAP, perform the following steps:
Register the module as remotely callable in the RFC server system.
In the function module Administration screen (transaction code SE37), set the field Can be called via REMOTE CALL. Registering a module as remote causes an RFC stub to be generated for it.
Write the code for the function module.
Create the destinations.....................
Displaying, Maintaining and Testing Destinations
To display, create or modify destinations, choose Tools ® Administration ® Administration ® Network ® RFC destinations or enter transaction code SM59.
Remote Destinations are stored in table RFCDES. The RFCDES table describes logical destinations for remote function calls.
It is not possible to maintain the RFCDES table directly.
You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® AcceleratedSAP ® Customizing ® Execute Project ® SAP Reference IMG.
In the Implementation Guide, expand the following hierarchy structure:
Basis
Application Link Enabling (ALE)
Sending and Receiving Systems
Systems in Network
Define Target Systems for RFC Calls
Displaying Destinations
The initial screen for this transaction displays a tree:
Different connection types (i.e. partner systems or programs) are possible. For further information, see Types of Destinations.
To display all information for a given destination, double-click it, or place the cursor on it and press F2 .
To search for a destination, press the Find button and specify your selection. You get a list of all entries matching your selection. Place the cursor on the one you want, and press F2 or simply double-click the destination. All information for the given entry appears.
Creating Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
All available connection types are explained in Types of Destinations.
To create a new RFC destination, press the Create button. A new screen is displayed with empty fields for you to fill in.
If you want to create a new destination
As you create a remote destination, you can specify a particular application server or a group of servers for a balanced distribution of system load.
For details of the destination parameters, see Entering Destination Parameters.
Changing Existing Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
You can display all information for a given destination by double-clicking it or pressing F2 on it.
To change an existing destination, double-click it, or place the cursor on it and press the Change button.
For details of the destination parameters, see Entering Destination Parameters.
Testing Destinations
To test a destination, choose the appropriate function from the Test menu.
Connection (also available via the Test connection pushbutton)
Authorization (checks logon data)
Local network (provides a list of application servers)
You can use the CALL FUNCTION statement to call remote functions, just as you would call local function modules. However, you must include an additional DESTINATION clause to define where the function should run:
CALL FUNCTION RemoteFunction
DESTINATION Dest
EXPORTING
f1 =...
f2 =...
IMPORTING
f3 =...
TABLES
t1 =...
EXCEPTIONS......
The field Dest can be either a literal or a variable: its value is a logical destination (for example, "hw1071_53") known to the local SAP System. Logical destinations are defined in the RFCDES table (or the TRFCD table in R/2 Systems) via transaction sm59 or the following menu path: Tools ® Administration, Administration ® Network ® RFC destinations. You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® Customizing ® Enterprise IMG. In the Implementation Guide, you can then choose Cross-application components ® ALE ® Communication ® Define RFC destination.
The remote function call concept, for example, allows you to access a function module in an R/2 System from an ABAP program in an R/3 System. If you want to read a customer record from your R/2 Systems database, create a remotely callable function module in the R/2 environment which retrieves customer records. Call this function from your R/3 System using a remote function call and listing the destination for the target R/2 System:

Call RFC Function Module and return 1000 records at a time

I would like to call a Remote Enabled Function Module from a non SAP system. This function module will select data from the database and return it to the calling program.
Suppose there are 100,000 records that need to be returned, but the calling module would like the data in chunks of 1000 records. Therefore the calling program would call the FM 100 times.
How do I code the function module to know on each subsequent call to grab the next chunk of 1000 records?
Let me know if additional information is needed.
Thanks,
Aaron

Hello,
Here is how you can go for this issue:
1. Create one RFC function module with following parameter. These parameters are with respective of chunking logic.
     Import: Package Size
     Export: Total number of records
     Changing: chunk count
Implement following logic:
1. First of you need to know how many chunks you need to fetch for that get the count of total number of records. This is one
    time activity so you better maintain one flag import parameter will be set to 'X' only first call.
2. Get the number of chunk using total number of records / chunk size for e.g. 1000 / 100 so chunk count = 10.
3. Define internal chunk counter in function module which will be used to locate the correct chunk depending on the chunk
    counter value sent from calling program.
4. Send first call with package size 100 and chunk count = 1, execute select statement and increment internal
    chunk count check if chunk count = internal chunk count in current case chunk count = 1 so exit select statement and return
    with first chunk.
5. Send second call with package size 100 and chunk count = 2. Execute select statement and check chunk count with internal
    chunk counter, in current case it will be 1 so skip that data and go for next chunk of 100 records increment internal chunk
    counter. In this case it will match with external chunk count = 2. load output table with that data and return to calling program.
6. Repeat step 4 until you reach last chunk.
You need to use SELECT...ENDSELECT with PACKAGE SIZE addition so for every loop it will return number of records mentioned in package size.
Hope this helps.
Thanks,
Augustin.
