JTextArea mouse handling related question

Hey All,
I've been beating my head off a wall for this for too long, I'm one bug away from shipping here, and this bug has been there through the whole development cycle.
I have a JTextArea which is to be a member of a class which fits into a hierarchy of manipulatives (objects you can place on screen and manipulate). Default properties of these manipulatives that must not change are that they can be grouped (working fine), clicked on with mouse to manipulate (working fine), and clicked on with mouse to move around the screen (herein lies the problem).
I currently have a mouselistener listening to the "drawing area" (a JComponent that all manipulatives get placed onto to be interacted with). When a mouselistener is added to the JTextArea giving the drawing area's listener as the cather of events, the e.getPoint method returns varied results. Sometimes it is the point relative to the origin of the drawing area, sometimes it is the point relative to the origin of the JTextArea (it's upper left corner). I suspect I have errors with Listener overloading, but I could be completely offbase as well.
What I'm intersted in, is having it setup so that e.getPoint() returns the JTextArea's location relative to my drawing area so that I can move it around the drawing area easily enough. I've tried treating the JTextArea specially, checking to see if it is the source, but e.getSource returns an anonymous instance of the JTextArea so I can't actually get that JTextArea's location on the screen.
If anyone can offer any suggestions, I would really appreciate it. If I've worded this so that it is too confusing to understand, feel free to contact me directly and we can arrange something.

But event.getSource is returning an anonymous instance of a JTextArea. And I want to go to a JComponent I have implemented coordinate space.
I haven't had a chance to completely attempt this. I have to restructure some other aspects of that code yet. But I thought I'd ask if the anonymous class returned by event.getSource would cause a problem

I want to check all functions of PCI 6534.I have read the user manual..I have some memory related questions.Please help me for that.

I want to check all functions of PCI 6534.I have read the user manual..I have some memory related questions.Please help me for that.
1.)If i am using the continuous output mode.and the size of generated data is less than 32 MB.If i want to preload the memory,what should i do?I want that first of all i load all my data to onboard memory & then i want to make start the transfer between 6534 & peripheral.Is it possible?As per me it should be.Plz tell me how should i do this?I think that in normal procedure the transfer between 6534-peripheral & outputting data from pc buffer to onboard memory works parallely.But i don't want this.Is it poss
ible?
(2).Similarly in finite input operation(pattern I/O) is it possible to preload the memory and then i read it?Because i think that the PC memory will be loaded automatically when 6534 acquires the data and then when we use DIO read vi the pc buffer data will be transferred to application buffer.If this is true,i do not want this.Is it possible?
(3) One more question is there if i am using normal operation onboard memory will be used bydefault right?Now if i want to use DMA and if i have data of 512 bytes to acquire.How will it work and how should i do it?Please tell me the sequence of operations.As per my knowledge in normal DMA operation we have 32 Bytes FIFO is there so after acquisition of 32 bytes only i can read it.How it will known to me that 32 bytes acquisition is complete?Next,If i want to acquire each byte separately using DMA interrupts what should i do?Provide me the name of sourse from which i can get details about onboard memory & DMA process of 6534 specifically
(4).In 6534 pattern Input mode,if i want to but only 10 bits of data.and i don't want to waste any data line what should i do?

Hi Vishal,
I'll try to answer your questions as best I can.
1) It is definitely possible to preload data to the 32MB memory (per group) and start the acquisition after you have preloaded the memory. There are example programs on ni.com/support under Example Code for pattern generation and the 6534 that demonstrate which functions to use for this. Also, if your PC memory buffer is less than 32MB, it will automatically be loaded to the card. If you are in continuous mode however, you can choose to loop using the on-board memory or you can constantly be reading the PC memory buffer as you update it with your application environment.
2) Yes, your data will automatically be loaded into the card's onboard memory. It will however be transferred as quickly as possible to the DMA FIFO on the card and then transferred to the PC memory buffer through DMA. It is not going to wait until the whole onboard memory is filled before it transfers. It will transfer throughout the acquisition process.
3) Vishal, searching the example programs will give you many of the details of programming this type of application. I don't know you application software so I can't give you the exact functions but it is easiest to look at the examples on the net (or the shipping examples with your software). Now if you are acquiring 512 bytes of data, you will start to fill your onboard memory and at the same time, data will be sent to the DMA FIFO. When the FIFO is ready to send data to the PC memory buffer, it will (the exact algorithm is dependent on many things regarding how large the DMA packet is etc.).
4) If I understand you correctly, you want to know if you waste the other 6 bits if you only need to acquire on 10 lines. The answer to this is Yes. Although you are only acquiring 10 bits, it is acquired as a complete word (16bits) and packed and sent using DMA. You application software (NI-DAQ driver) will filter out the last 6 bits of non-data.
Hope that answers your questions. Once again, the example code on the NI site is a great place to start this type of project. Have a good day.

Two related questions: ColdFusion 10/Java applications and J2EE supported servers

I have two related questions:
1. CF10 and integration with Java Web applications
We have a couple of Java applications running on JRun and interfacing with CF9 applications. The JRun clusters were created through the JRun Admin and, apart from lack of Axis 2.0 support, have served us well for years now. And, as would be the case, the ColdFusion9/Java/Flash application is a critical public-facing application that the business uses for bidding on projects.
It appears that with ColdFusion 10 on Tomcat, we will not be able to run those Java applications on a Tomcat-CF10 JVM cluster. Is this correct? IF so, what are our options?
2. J2EE Application Servers supported by Adobe for CF10
Which of these is correct?
A. This URL (http://www.adobe.com/products/coldfusion-enterprise/faq.html) states "ColdFusion 10 supports IBM® WebSphere, Oracle® WebLogic, Adobe JRun, Apache Tomcat, and JBoss."
B. This URL (http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/products/coldfusion/pdfs/cf1 0/coldfusion10-support-matrix.pdf) states:
"J2EE application servers: WebLogic Server 10.3, 11.1, WebSphere Application Server 7, ND 7 JBoss 5.1, 6.0, 7.1.0"
I *think* "A" above is wrong re. support for Adobe JRun. It does not specify a version of Apache Tomcat unless it is simply referring to the custom version the comes with CF10.
Option "B" above shows no support of Adobe JRun or 'standard' Apache Tomcat.
Thanks,
Scott

Question 1 above was answered: "No support for Java web applications under CF10's custom version of Tomcat"
Question 2: No answer yet: Is Apache Tomcat (NOT Adobe's customized version) supported for CF10 J2EE deployment? I do not see any installation instructions on how to install CF10 on Apache Tomcat 6 or 7.
Is anybody using Apache Tomcat as their J2EE app servers and, again, NOT Adobe's customized/limited version?
Thanks,
Scott

Hi,
I was going through some of the threads available in PLM forum, but to my surprise, most of the threads posted are related to PM, which should have been posted in EAM forum.

Despite the clear instructions given my the moderator, PM related questions are still posted to PLM forum and some of the active participant of EAM forum answers these questions in PLM forum. It would be nice if those threads are moved to appropriate forum, so that the relevant informations are available under one forum, also, PLM forum should be monitored regularly and inappropriate threads are to be moved to their respective forum.

I hate to say this, but I often see the same thing, and I've never been able to figure out exactly what triggers selectability vs. non-selectability, but I suspect some of it has to do with tranparency flattening in particular, and possibly text wrap in cases where that comes into play. ID optimizes the PDF it creates, I think, and that might cause text, or even images, to be broken into chunks in funny ways. It occurs to me that turning off optimzing for fast web view might help in this regard.

I just got a call today that I reached my 300GB limit for the month. I called and got a pretty rude response from the security and data usage department. The guy told me in so many words that if I do not like or agree with the policy that I should feel free to find another service provider.!!! I tried to explain that we watch Netflix and XFinity on-demand alot and I was told that that can not be anywhere close to the data usage. I checked my router and watching a "super HD, dolby 5.1" TV show on Netflix will average about 5-6 GB per hour (1.6MB/s) ... sp this means that I can only watch no more than 1-2 Super HD TV shows a day via Netflix before I run out of my data usage. This seems a bit redicilous doesn't it? Maybe the TV ads about the higher speed than the competition should be accompanied with "as long as you don't use it too often" Not a good experience ...

Ok, I’ve been developing Windows apps since Win 3.1 (yeah, a long time) and have always admired the Microsoft attitude towards Developers and it’s desire to educate and empower R&D.
So, I’m wondering what’s going on? Why am I being asked to have an account to develop anything for MY own PC? Why am I being asked for my Microsoft account password, repeatedly, when I’m just looking up documentation on UserControl or C3 keywords…
repeatedly? This is nothing short of annoying and it gives me pause and concern about the ecosystem. Is the plan to lock down programmer’s capabilities, knowledge and tools?
I’m involved in the TAP program for Windows 10 and have voiced concerns in the same category with regard to installation and deployment of Universal Apps. Security is not a reasonable excuse. Some of us love to program and actually
control their PCs. We are not planning to sell everything we write on the Windows Store. What happened to programming something cool for your home network or just for friends? We need, and used to have, Microsoft’s support in doing
this sort of thing. Documentation and tools are more important now than ever. I’m saddened to see the direction things are heading…
If there is a sane reason I’m being badgered to ‘log in’ to read .NET documentation every hour, please share. If not, please consider lobbying to get things back on track.

Button, or other panel related question

so, if any of you have read my previous topic about painting rectangles in a panel, that worked great, but now i need to mkae those rectangles components so that when someone hovers over it or clicks on it it displays information at a certain area. I know how to make listeners and how to add buttons in a panel, BUT how do I add buttons at a specific coordinate. This program graphs data on a specific scale and therefore adding a button in the approximate area using a grid layout will not be good enough. Is there anyway for me to place the the button/component/object at the extact location that I want?
thanks in advance

In future GUI related questions should be posted in the appropriate GUI forum (likely Swing).

MDM 5.5 related questions

Dear Roman,
We have been reading all of your blogs and articles on SDN.
We have many questions related to SAP MDM 5.5, few of which are listed below:
Q1. Whether cross compatibility for different ERPs will be provided or not? (for Siebel, PeopleSoft etc)
In case of MDM 3.0, it was supposed to be developed on Project Basis.
[Rytov, Roman] Since MDM is an SAP's product I don't know (and don't think) any transformation vehicle will be provided for 3-d party products out of the box. On the other hand, anyone can get all necessary knowledge to bring external data into MDM and back. I've been working with several customers placing MDM as a data hub (a scenario that for some reason hasn't gotten a separate bullet in the MDM scenarios diagram but widely adopted by customers). So you can bring data from external systems to MDM (by either the APIs or with help of the ImportManager) and distribute it back to the same (or other) systems leveraging the Syndicator or the APIs again.
     [Satyen] With the help of APIs/ Import manager, we can get the data from external systems into the SAP MDM but then <b>we need to have functional knowledge</b> to do mapping manually between MDM business objects and different business objects as Material from CRM, Business Partner from CRM, Business partner Relationships from CRM. In one of the blogs by Kevin Isaacson , its mentioned that SAP MDM is packaged with predefined repository and import maps for the supported objects like material, vendor, customer.
     1. So whats the exact scenario for cross-client support? Do these import maps provided by SAP support external systems like PeopleSoft, Siebel?
     2. In the SAP MDM 5.5 Import Manager document provided by SAP, its not talking about client connectivity but only about how import can be done? Where can we find this information?
     3. Is XI completely removed from IT scenarios? If yes, then how is it going to take care of data transfer with different data sources?
     4. Can you please elaborate more about DATA HUB scenario? I believe, Oracle is also coming with similar technology to SAP MDM which supports only Central Master Data Management scenario. In Oracle terminology, they call it Central Data Hub (CDH).
Q2. Can we build a legacy system on top of Central Repository? If yes, how? Is Reverse Engineering possible?
[Rytov, Roman] I'm not sure I understood the question but you may probably treat your MDM system similar to a RDBMS with an additional intelligent layer. In this light you can build on top of MDM whatever you want by using either the APIs only or by leveraging the ImportManager and the Syndicator. I tell you that one of the customers that uses MDM as a data hub at the same time in another MDM repository stores exceptions and other technical messages occurring during integration workflow with external systems. So they have a workflow module which uses MDM as a persistence (MDM itself) and a presentation layer (the client) for managing exception handling. Only your fantasy and the common sense limit applicability of MDM.
     [Satyen] I understand that by using APIs, we can access the underlying RDBMS tables of MDM repository but then
       1. how can we link the complex relationships maintained between Main Table & various Lookup tables, main table & special tables?
       2. I believe the data in the MDM repository is maintained in a very complex way (Delimiter separated) and is manipulated on the fly by the C++ code using pointers & rich/efficient string operations. So how can we access it directly and make use of data from the repository?
       3. In case of WorkFlow module, since it is quite independent of Main table and lookup table linkages, we can make use of it for persistence but then for other modules, it must be quite complex thing to do so.
Q3. Will there be separate repositories for IT scenarios, GDS & Catalog publishing?
[Rytov, Roman] GDS is a separate application although built upon MDM. It has its own repository which can be accessed from the client. I don't know if there are any limitation on such concurrent usage. I have to check it and will come back to you.
     [Satyen] We attended the Webinar hosted by Klaus David on GDS 1.0, as per that GDS maintains its own repository which can co-exist along with MDM repository on the same DBMS server but then in MDME, which mainly covers business scenarios only, does not really talk about Master Data harmonization, central master data management.
     1. If it is the case, then dont you think itll be duplication of efforts for maintaining various repositories for GDS, MDME & IT scenarios?
Can we have an illustrated difference between Qualified field, Qualifiers, Product families & Data Groups?
[Rytov, Roman] It's a big topic but in a few words the answer is: Qualified fields and qualifiers are means and tools of qualifier lookup tables. I'm writing now a set of articles talking about it and update you when it's ready. Product families are similar to virtual taxonomy. So you create an additional level of your taxonomy but virtually, choosing attributes to classify it. No additional branches are created. Data group is just an hierarchical structure for storing binary objects (PDF, TextBlocs, Images and others). It helps organize not structured binary data and link it later to your catalog's objects.
     [Satyen] We understood about the product group.
     1. Can you provide the exact definition of Qualifier? Whether is it a part of Main table or Qualified Lookup table?
     2. Whats the exact difference between Sub-category and Product family? As per SAP document, the product family is a kind of taxonomy with some common Fields AND/OR Attributes. Can you provide some example about it?
How data is harmonized in SAP MDM 5.5? What is the difference between Syndicator, GDS & SCM?
(Don't they have overlapping functionality?)
[Rytov, Roman] Let's see. The Syndicator is a tool opposite to the ImportManger - to export data from MDM to flat or XML file (currently implemented formats). GDS is an application for retail market built upon MDM. SCM - isn't it a SAP-based (ABAP) application? I'm not from the ABAP world so I don't know it. But there are few SAPBased applications having master-data module built in. Depending on business needs and technical requirements such modules can keep on serving their roles with or without integration with an external MDM. I'm trying to say again that there are no predefined MDM scenarios and some customer may wish use it as a central point of truth but others as a cleansing gate or a translator hub. An architect team should understand capability and cost of every module and in every concrete case make appropriate decisions.
     [Satyen] According to the SAP documents, we can use Syndicator to syndicate data with UCCNet, Transora (both of which are now going to merge).
     1. If its the case then why GDS is separately required in whole MDM scenario? Is it not overlapping the functionality of each other? Then how GDS can become a separate Business Scenario for SAP MDM 5.5?
Let me ask you a few questions. Did you take the basic standard 4-day course about MDM5.5? It's mandatory to kick off MDM learning and understanding.
[Satyen] Now in second week of August, we are going to attend the 5 days workshop conducted by SAP at Bangalore, India which can help us in understanding SAP MDM 5.5 in a much better way!
To understand how MDM fits to a system landscape I advise you to listen to my e-Book if you haven't yet found it:
https://www.sdn.sap.com/sdn/url.sdn?res=/irj/servlet/prt/portal/prtroot/com.sap.sdn.wcm.compound.docs/library/events/webinars/mdme in your it landscape/mdme 5.5 in your it landscape
[Satyen] Thanks for providing the URL. Its really useful! Is there any way by which we can download this presentation with audio?
We're developing a 2-day workshop for advancing MDM data modeling which will mostly be comprised of hands-on experience and brainstorming discussions. It's planned somewhere in October but for now it's not clear when and where it will be given.
[Satyen] Its definitely going to be very helpful to everyone as in SAP MDM 5.5, you can design the repository in various ways. So these discussions/brain storming sessions will be really useful to everyone. Please let us also know about it.
Good luck with MDM!
[Satyen] Once again thanks for everything!!
Roman
Thanks in advance.

Some Kernel and optimization related questions

Last monday I asked about what was the best way to compile a kernel to apply a patch ( solving an hibernation resuming problem). Using the ABS turned to be an easy solution with a shiny patched kernel that works GREAT. Yestertay, I tried e4rat in order to speed up my boot process, wich now takes 1 min or so from burg to kde4 with Chrome, Eclipse, Spideroak and Dropbox all full loaded and functional on my laptop when before using E4rat that took nearly 3-4 minutes.
Laptop specs: Fujitsu Esprimo Mobile V6535 --> Intel T4300, 4 GB 800MHz DDR2 RAM, Intel GMA 4500M, atheros wifi chipset. Non-laptop related hardware (if needed to have in mind) Microsoft Natural Ergonomic Keyboard 4000 and Lifechat LX3000 headset, Logitech G5 mouse.
Currently the laptop is my main computer and used to internet-browsing, programming and sometimes to watch movies. No games.
I really enjoyed all the tweaking involved on the last week with the kernel patching and e4rat, so I want more.
Ok then, I was going to try readahead ( https://wiki.archlinux.org/index.php/Readahead ) and then I see that on the AUR there are some packages related to it, and this is the point when the questions come:
1) The article on the wiki points out to readahead-list, but there what seems to me another implementation, readahead-fedora. To me it seems obvious that the implementation may be different, but, what are the differences betweent the two?
2) what has to do ureadahead with the two said before? Plus, what is the point with the package description? "ureadahead is used during boot to read files in advance. readahead-list and sreadahead are out-of-date. Needs patched kernel!" The last part has not problem to me as kernel26-yi 2.6.38.2-2 seems to patch the kernel to support ureadahead, but is the first sentence, the one that talks about readahead-{list,fedora} being outdated. Could someone clarify this?
3) About kernel26-yi 2.6.38.2-2. ¿Does only a kernel install or a full compilation? ¿What kind of patches does it ship with? (Aside from ureadahead support)
4) https://wiki.archlinux.org/index.php/Im … tom_Kernel . Aside from the warning about the possible trouble with modules, is there any kind of common incidence with that options? Any kind of suggestion about more config options related to performance or to have in mind?
5) Any other kind of suggestion?
Feel free to suggest any option that trades RAM for performance, currently only a third of my RAM is used (or said in other words, more than half of my RAM is being unused (therefore useless)) and only gets to half or 2/3 when virtualbox is launched (twice everyday, during 5 mins or so)
Thank you all in advance for your help.
EDIT: I forgot to say, I like KDE and changing it is not an option, but feel fre to comment options on that way if you consider it would be a big deal.

Yes, I forgot to mention that, but already using fastboot parameter (if that is the fastboot on my burg linux line, then i'm using it). As said, I'm very happy with my current status about booting and performance, no complains, only that something inside me wants to keep pushing on this.
I read a bit about BFS and the CK patches today, maybe I'll give it a try, maybe not now, but someday sure.

3) All requests are loaded for day,monthly and yearly also.
4) Also to note down time taken for loading of critical infocubes which are used for reporting.
5) Is there any break in any schedules from your process chains.
It's totally a client specific tool.
The common features here can be
A ticket Id,
Priority,
Consultant ID/Name,
User ID/Name,
Date of Post,
Resolving Time etc.
There ideally is also a knowledge repositary to search for a similar problem and solutions given if it had occured earlier.
You can also have traning manuals (with screen shots) for simple transactions like viewing a query, saving a workbook etc so that such queried can be addressed by using them.
When the problem is logged on to you as a consultant, you need to analyse the problem, check if you have a smilar problm occured earlier and use ready solutions, find out the exact server on which this has occured etc.
you have to solve the problem(assuming you will have access to the dev sytem) and post the solution and ask the user to test after the preliminary testing from your side.
Get it transported to production once tested and post it as closed i.e the ticket has to be closed.
---If there is a dataload failure, what steps/checks do i need to follow. etc.
it means thats depends upon the failure we need to monitor and take corrective action ..
generally we do in load failures...
ST22 for any shortdumps
sm21 for log entries and
TRF entries
sm12 for any locks
we need to analyze from these t-codes.
changing query/object
-change ticket from open to working.
-get additional details if any required.
-create transport request in dev.
-make the change and save in transport.
-check that transport goes through OK.
-do testing in QA system.
-after testing is OK,get change transported to prod.
-update ticket and resolve it.
-usually helpdesk closes ticket after confirmation with user who raised ticket.
data load failure
-regularly check rsmo(monitor) for data load failures.
-if load fails,get details from details tab of monitor.
-usual errors are:master data missing,special characters in data,datasource not replicated,delta load issues etc.
-get root cause of error,and fix data load manually.
-check that manually updated data is GREEN and available for reporting in data target.
-update ticket and resolve it.

1. Why there is frequent load failures during extractions? and how to analyse them?
If these failures are related to Data, there might be data inconsistency in source system. Though we are handling properly in transfer rules. We can monitor these issues in T-code -> RSMO and PSA (failed records) and update.
If we are talking about whole extraction process, there might be issues of work process scheduling and IDoc transfer to target system from source system. These issues can be re-initiated by canceling that specific data load and ( usually by changing Request color from Yellow - > Red in RSMO). and restart the extraction.
2. Explain briefly about 0record modes in ODS?
ORECORDMODE is SAP Delivered object and will be added to ODS object while activating. Using this ODS will be updated during DELTA loads.. This has three possible values ( X D R).. D & R is for deleting and removing records and X is for skipping records during delta load.
3. What is reconciliation in bw? What the procedure to do reconciliation?
Reconcilation is the process of comparing the data after it is transferred to the BW system with the source system. The procedure to do reconcilation is either you can check the data from the SE16 if the data is coming from a particular table only or if the datasource is any std datasource then the data is coming from the many tables in that scenario what I used to do ask the R/3 consultant to report on that particular selections and used to get the data in the excel sheet and then used to reconcile with the data in BW . If you are familiar with the reports of R/3 then you are good to go meaning you need not be dependant on the R/3 consultant ( its better to know which reports to run to check the data ).
4. What is the daily task we do in production support.How many times we will extract the data at what times.
It depends... Data load timings are in the range of 30 mins to 8 hrs. This time is depends in number of records and kind of transfer rules you have provided. If transfer rules have some kind of round about transfer rules and updates rules has calculations for customized key figures... long times are expected..
Usually You need to work on RSMO and see what records are failing.. and update from PSA.
5. What are some of the frequent failures and errors?
As the frequent failures and errors , there is no fixed reason for the load to be fail , if you want it for the interview perspective I would answer it in this way.
a) Loads can be failed due to the invalid characters
b) Can be because of the deadlock in the system
c) Can be becuase of previuos load failure , if the load is dependant on other loads
d) Can be because of erreneous records
e) Can be because of RFC connections
These are some of the reasons for the load failures.

Ironport Whitelist and related questions

Hi all,
I have recently started at a new position for a company that is utilising ironport as the email spam filtering/virus checking appliance.
Almost immediately after starting in my position issues were being discussed, where the senderbase reputation scoring was marking a sister companies mail as spam - obviously due to a bad reputation.
It was important that these mails were delivered and the obvious answer seemed to be to whitelist the domains, which was implemented by another support person. After the whitelist setting was applied though the mails were still be rejected due to being suspected spam - there is no quarantine setup.
Today I logged into the boxes to see if I could syslog the mail logs to a seperate linux server and suddenly got wrapped up in this problem. I had a look and could see the domains in the whitelist section within the HAT, after doing some reading I can confirm the whitelist section was ordered as being number 1 in the list and by looking further it looks like the whitelist domains were via the 'add to sender group' button within the monitoring overview screens (this is assumed as both .sistercompany.com and sistercompany.com were appended to the whitelist).
After a few hours of reading up I couldn't understand why the whitelist wasn't working, I even did a lookup of the domain in the monitoring overview search section for mail recieved by sistercompany.com and could see that it belonged in the whitelist group. I got further confused when reading the help and support guide - it had screenshots that looked very similar to our setup [within the HAT overview and Mail Policies], however it had an sbrs for the whitelist set between 6 and 10, where as that was blank on our system, nowhere in the document would it describe why this sbrs value was set. Bearing in mind I have only had a few hours of experience with this product, so these maybe silly questions but:
Why would you add an sbrs value to the whitelist - I would have thought whitelists would ignore any score presented.
If number 1 has nothing to do with why these domains were still being flagged as spam, has anyone got any suggestions as to what the issue maybe?
For a small bit of information we have the C660 appliances installed.
Any help would be much appreciated

I'm taking a wild guess here since there are a lot of missing details. Forgive me if I'm covering ground you've already trod.
Remember that the HAT controls how incoming SMTP connections are handled, so entries in the HAT must correspond to the remote SMTP servers that are connecting to you. You don't put the "domain" part of "user@domain" in the HAT ("sistercompany.com" in your case), you put in the the domain names of the actual remote SMTP servers or a wildcard that matches them all. In your case, this might be ".sistercompay.com" (note the leading "." indicating that this will match any domain name ending with ".sistercompany.com"), but only if their SMTP servers have host names in that domain.
Whitlisting by domain name requires that the IP addresses of those remote SMTP servers have correct rDNS. If they don't, you'll have to list them in the HAT by IP address. FYI, we never put anything in the HAT by IP address unless it is unavoidable. Using domain names and requiring correct rDNS forces good DNS hygiene, and also provides a layer of abstraction. The server's address can change, but so long as the DNS is kept up to date we don't have to change our HAT entries.
You can see from the mail logs what sender group is being applied on each SMTP connection. Find one of the rejected messages in the log and see what sender group its connection landed in. If it didn't land in the whitelist (which will almost certainly be the case, given that the message was not in fact whitelisted), then you know the HAT entry is wrong. You can also use the log to determine the actual domain name of the remote server, assuming the rDNS for its IP address is correct.
The example screenshot in the manual showing SBRS between 6 and 10 being whitelisted is demonstrating that you can whitelist by SBRS as well as by explicit listing in the sender group. Your whitelist simply isn't doing this, which is fine. In this age of rampant spamming from stolen accounts on reputable servers, whitelisting by SBRS can let spam in. We raised the lower limit from 6 to 8 several years ago after getting hit in this exact way.
