Ml_linkage entries (two modules in one)

I have two modules that I need to incorporate into one since they have shared state. I have successfully done this by adding a second entry to the ml_linkage member of the modlinkage structure. When I run modinfo, there are two entries under the same ID number that correspond to my two modules. This does not seem uncommon: a number of network modules have two entries, and NFS even has four.
Things seem to be working as they should, however I have a few questions to make sure that this approach isn't a mistake, given that these modules are still in early development.
FAQ 4.11 [1] states that the approach I have used should not work, and recommends using a third module that each of the other modules depends on. Similarly, FAQ 3.25 [2] offers another solution in which a third module is used to export a global variable. Are these approaches preferable to the approach I have taken and, if so, why? It seems cleaner to me to embed these two modules within one, rather than create external module dependencies.
[1] http://developers.sun.com/solaris/developer/support/driver/faqs.html#QA4.11
[2] http://developers.sun.com/solaris/developer/support/driver/faqs.html#QA3.25
These FAQ entries, along with the modlinkage(9S) man page and "Writing Device Drivers" prior to Solaris 8, seem to be saying that what I'm doing shouldn't be working (or allowed).
However, "Writing Device Drivers" for Solaris 8 and beyond remove the text that says drivers only support one module and that ml_linkage[1] is required to be NULL. Furthermore, the comment before struct modlinkage in sys/modctl.h says that Sun supplied modules use up to three ml_linkage entries.
Any enlightenment (perhaps history) on this issue would be appreciated. I'm hoping to determine whether the approach I'm using is somehow broken, not recommended, or just not documented.
Thanks,
Andrew

Hi,
Don't worry, you do not need to promise kudos to get help
Did you try your first program (1 module used) with both modules? Maybe one is damaged.
Then, have you tried your second program with letting only one module plugged in the chassis?
If I'm right, both modules can run totally independant, and you don't need to synchronize clocks or whatever to have them working. (but you can if it's the behavior you need)
Just start the module at the beginning of a sequence, then read inputs in a loop (without timing VI). Think about setting the Rate before starting.
Hope this helps

Can I communicate with two different FP 1000 modules through one labview program at the same time

I am wondering could you communicate with two seperate FP 1000 modules with one labview program, using a tab control, with page 1 of the tab communicating with one FP 1000 through com port 1 and page 2 of the tab control communicating with another FP 1000 module through com port 4, using different iak files for both. Can I do it through using those wireless modems supplied by National Instruments. Sorry I dont have a name for them.

Noely,
Within a single IAK file, you can have multiple FieldPoint modules on separate COM ports. There is no need to use separate IAKs for the program you are describing. Actually, older versions of NI-FieldPoint do not support having multiple IAKs in use simultaneously (I am not sure whether it is currently supported).
As for the Radio Modems, they are called SRM-6000s and can be used simultaneouslyon different serial ports. Although, using the SRM-6000 in a single master multi slave arrangement, you could use a single serial port to talk to both FP-1000s (3 SRMs total). You will need to configure the FP-1000s to have separate addresses (DIP Switch setting).

No Un-ambiguous Selection of Mapping Module (above one) for BUPA_MAIN BDocs

Hi All
I seem to have hit a snag here. I am trying to replicate customers from CRM to ERP but am getting these two errors:
Main error: Partially send, receivers have errors.
No un-ambiguous selection of mapping module (above one) for BDoc type 3932399B34D6279BE10000000A11449E.
Service that caused the error: SMW3OUTBOUNDADP_CALLADAPTERS._
I have searched on Googleand SDN but have come up with nothing as far as these errors are concerned. We have managed to replicate Business Partners, Materials and Conditions from ERP to CRM without any problems but when it cam e to replicating back, these errors started popping up.
I have used all the tools for analysis but have come up with nothing the really suggest to me what is wrong. I have monitored queues, traces and dumps. I have played around with the filter setting and all.
With regards to the process itself, i followed the C03 best practices config guide and i believe that i have everything in place. Here are the steps i followed:
1.Create an Internal number range for the CRM customer group.
2. Assigned the number range to the Customer group
3. Created a corresponding number range (External) in ERP and a corresponding CRM Customer account group as a copy of the standard 0001 Sold-to-party account group and assigned the number range to it.
4. Defined Partner functions (SP, SH, BP, and PY) for the account group
5. I mapped the CRM classification for customers (B) to the created account group (CRM Customer)
6. I synchrponized the fields for the account group created and the BP roles in CRM including changes on a per client (BUPA) basis.
7. I redowloaded all the cutomizing objects (though i only needed the DNL_CUST_KTOKD) for the sake of the mappings directly in CRM or R/3 Account group maintenance during the creation of the BP.
8. I customized the filter settings in BUPA_MAIN and included the BUT100 table for the filetring of the customers who were created as SP, BP, PY, or SHand who belonged to the Customer group we had created. (BUT000->BU_GROUP & BUT100->RLTYP) for source site CRM.
9. Activated the necessary function modules through transactions COM_BUPA_CALL_FU in ERP and CRMC_BUT_CALL_FU in CRM according to [http://help.sap.com/saphelp_crmscen70/helpdata/en/60/85b5d333f4174b8e982c1c15db35f3/frameset.htm]
10. Using transaction R3AS i sought to replicate the BUPA_MAIN object.
Because of the few customers created in CRM, it only executes within a single block so the queues would be empty by the time SMQ1 and SMQ2 are executed. R3AM1 shows it as running. SMW01 shows the above error.
When creating a BP through the tx code BP, the main error would be Technical error(Incomplete) and the two other errors as mentionme above would also be there
Is there anyone out there who has met this very same problem or knows the solution to this.
Thanks in advance.

We managed to get a solution to the problem. Here it goes:
When a new adapter object (e.g a custom one) is created, the SMOFOBJECT table is populated with the entry and, in turn, the SMOFUPLMAP is populated with the object and the mapping module for uploading to R/3. During the upload process, a search for custom mapping modules is done and if not found the standard mapping modules are used. However, and it seems weird since it seems as if it applies to the BUPA_MAIN object or the corresponding mapping module (BUPA_MWX_BDOC_UPLOAD_MAIN_R3), there has to be a one-to-one mapping between an mapping module and adapter object.
I had created a custom adapter object (Z_BUPA_MAIN) to which I wanted to put some custom filters and did not want to test with the standard object. So two objects using the same mapping module ended up existing in the SMOFUPLMAP table (one-to-many mapping). The function module in which this happens is the GET_UPL_FUNCTION_FOR_OBJ.
So the solution would be to delete the object if it is not needed or to maintain the SMOFUPLMAP table to remove the entry. When you delete the object, it sometimes does not automatically/subsequently remove the entry in SMOFUPLMAP, so manual maintenance has to be done or the same object has to be recreated and have the mapping module allocated. After this, the problem would be solved. What is weird to me is that the only one-to-one mapping is allowed. I created a custom object for the download of conditions and I did not get that error. So it means that in this case you would have to copy the mapping module and create a custom one for the custom object.

Thanks for help.

Jim,
Before starting the database A, did you set ORACLE_SID=A from command line? You can run as many instances you want from single server provided you enough memory, processing power. Also try starting your instances usign window services and check and post some lines from alert.log for database A.
tnsnames.ora entry
DATABASE_A =

    (ADDRESS = (PROTOCOL = TCP)(HOST = salesrpt.net)(PORT = 1521))

About combing two array into one

Hi all,
I post a questiona bout converting an array of integer into char (byte) array and I got a solution already http://forums.ni.com/t5/LabVIEW/how-to-display-char-code-properly/m-p/2596087#M780368
However, I enouther another problem while dealing with an array of U16 type. I would like to extract the high and low byte from numbers (U16) stored in array. I extract the high and low byte for each U16 number and convert them as char, concatenate them to a string. Repeat this process for each element in the array so to get a big string with each element is a char for high and low byte. My code is enclosed as follows
It works fine but I am concerning the speed. Is that any other way to do it fast and don't use loop (in real case, I will deal with pretty big array many times, efficiency is a problem). Note that the high and low bytes array extracted from the original array with the module Split number.vi, but how can I combine these two array in one code with data arranged as high-low-high-low ... ?

You need to be more clear.
Looking at the code, you are dealing with I16, not U16. Also your index array primitives could be replaced by autoindexing. Your use of the feedback node only makes sense if you want to append strings forever with stale data, thus growing data structures without limits. If you only want to convert the current data, remove the feedback mode and use a "concatenate strings" with a single input. A for loop is one of the most efficient data structures and using it is not a problem. One way or another the code needs top oerate on all data.
All that said, I agree with Tim that most likely all you need to do is insert a typecast after the "to I16" and eliminate all other code.

Hi,
You only have to consider 2 things :
1. SAPTRANSHOST entry in hosts file will be the same for both systems
this mean that both systems will share the same transport directory
Regards,
Wojtek
This is not true. Your SAPTRANSHOST will remain the same, but you can (and should) specify independent trans directories with the DIR_TRANS and and EPS profile parameters to designate where the instance trans files should be located (i.e. /usr/sap/trans_SID). I recommend you make this change in the existing host first, and then clear out the trans directory. Let the 2nd instance install into it and then alter that one too (thereby moving the files to the new /usr/sap/trans_SID2).

SAP XI - Combine Two files as one in File Adapter

Experts,
I want to combine two files as one in File adapter itself. I am using a simple scenario of File-to-File where i am just sending the file from sender to receiver as it is , EXCEPT, i want to add one line at the end of the file .
I was thinking of doing this in File adapter , avoiding any mapping program in Integration Repository ..
ANY INDEA's ??
Regards,
Ashutosh

Hey
You have 3 options,first one can be to execute a OS command before message processing or use adapter modules to append the new line in the sender adapter.
the second option(and better one) is to do this via message mapping.
third option is to write a OS script and execute it after message processing on receiver file adapter.
one thing you need to make sure is that since OS scripts run on XI server itself(not on FTP server) so in case you are picking file from FTP server and delivering to FTP ,then you can't use option 1 or 3,you can only use option 2
Thanx

TWO CURRENCIES IN ONE Purchase Orders Release Procedure.

TWO CURRENCIES IN ONE Purchase Orders Release Procedure.
Please provide a solution if a release strategy is maintained for two currencies like USD and SGD for more clarification please Read the below Requirement.
Requirement for Singapore:
u2022          COMPANY Asia (Singapore) wants its own Purchase order release strategy is based on their local currency (SGD)
u2022          Whereas COMPANY is using only USD as currency in Purchase order release strategy.
u2022          Standard SAP works based on Character currency which is defining in Class of Purchase release strategy and converts with Local currency to compare with Character Currency.
Required analysis:
u2022          The value assigned in classification is based on Conversion from SGD to USD, Due to Exchange rate fluctuations the assigned value is differ by large amounts and hence system is either determining the higher release strategy or Lower release strategy
u2022          But during Release Strategy Configuration the Net order Value is assigned as 3600 USD considering the Exchange as 1.388889.
u2022          As per the exchange rate in the purchase order 1.3799 the system is calculation the PO Net order Value but the Strategy is Determined based on the value maintained according to exchange Rate 1.388889
In the Purchase Order the system is
Ex: Total Purchase Order Value is 4765.21 SGD and 3453.30 in USD
      For Level 1 the value limit is 5000 SGD if it exceeds 5000 SGD it has to go to his manager (Level 2) Exchange rate on 01.04.2008 is 1.3799.
System Considerations:
Possible Solution:
1.        Create a new Class with Characteristic with Currency Value SGD System should determine the class based on the combination of Plant 6000 and Document Category F Purchase Order.
2.        By using Enhancement spot with Function Module ME_RELEASE_STRATEGIE/ ME_RELEASE_STRATEGIE_EKKO
Logic:
1.        System will determine the class PUR_RELEASE from table T16FG if the system finds Plant as 6000 and Document Category as F Then replace PUR_RELEASE with New class as ZPUR _6000.
2.        Maintain Z table for the combination of Plant and Class for future requirement

Hi Mohamed,
You can create separate characteristics far all check points and assign those to class.

Two billing for one sales order for same customer

Dear All ,
I have a requirement of posting a two billings for one sales order.
One is for Sales and another is for commission...
Entry could be
Sales Entry - Db Customer
Cr Sales
Commission entry could be
Db - Cusomter
Cr- Sales commission income account (P/L)
We are having third party sales scenario , In this case billing is MIRO dependent.
Once the miro is done then only billing is possible ...
Could you please advise on that ..
Regards,
Sukh

Dear Ratish,
Thanks for yr reply.
I already did that but it is not serving business purpose.
Comm payment - comes diff time than sales payment.
so ,I will post one entry customer will get hit with total amount Sales + commission
like below
Let say 10, 000 is the sales value and 500 is the commission
So , This entry will get posted
Customer Db- 10,500
Sales Cr- 10,000
Comm Income Cr- 500
But, As I said sales amt will be paid before so We need to clear it partially and some time customer pays also diff amount due to some defect.
So, We wont be knowing for which case we have or havnet received the payment against commission.
As , Customer account is got hit with total amount( Sales+ Comm..value).
Pls advise how to solve this.

Sukh

Currently when a device, say a router goes offline we receive two Active 'Unresponsive' alarms for the router and then when it comes back online we receive two Cleared 'Unresponsive' alarms. All have their own unique Event ID. (shown below)
I was wondering if anyone could help me to config LMS to send only one Active 'Unresponsive' notification when a device is offline and then one Cleared 'Unresponsive' when the device is back online.

so please , How can I make two Canvas in one Window only ?
and thanks in advance

this code work with me :-

How to link two modules of data when querying the data ?

Hi ,
I am using Designer editor to create a form .
I am having two modules with the tables EMPLOYEE and department .
In my form ,I want to display the data of each employee with the department data .
How to link the two tables data in the designer ?
How to View the generated triggers in the designer ?
Thanks
Sai

Two modules means two forms. These are unrelated.
Or do you mean that you have one form with two blocks (master-detail)?
How to link the two tables data in the designer ?You have to define the foreign key on the tables. Based on this FK Forms Generator will generate the code if you create two Module Components (master-detail) in the module. Don't forget to define the Key Based Link on the master block.
How to View the generated triggers in the designer ?You can't. You have tom open the generated FMB file in Forms Builder to see what code is generated.

Data entry in module pool screen

Hi all,
I have created a module pool program. on the screen of the program, i have entered a dictionary field KNA1-KUNNR. On the second field on the screen, i have coded a search help to generate the F4 help based on the entries in the first field. Now the problem is that the entry made in the first screen is not available in the code, i.e. when i have entered a value in the first screen, in the debugger it shows the field as empty. i tried declaring a variable of the same name as the field, but it gives me error that the variable is already declared. any help will be appreciated.

Two FQDN on one machine.

I am trying to consolidate services on to as few machines as possible. Since you can setup multiple IP addresses, is it possible to have two FQDNs on one machine? I want to use a server to host files on my private network but also provide a public website. I already have the entries in DNS. I just don’t know if I can have two FQDNs on the same machine. It is as simple as just adding the new address?

If you are just talking about web hosting for two fqdn, then add another site in ServerAdmin:Web
Apache suppport virtual hosts. You could have hundreds of FQDN running under a single IP address.
In your case, you don't even need two IPs, but you could use them- or at least use them transitionally until you modify DNS and then just use on public IP.
If you want to add a second IP to the machine, you duplicate the port in SystemPrefs:Network. Show Network Port Configurations, then duplicate the ethernet interface and give that interface it's new settings.
