Principle

Hi, everbody. I want to know, how works (principle):when you protect a PDF file against edit, copy, print etc.
I need to know a technical principle of it....can you help me?

Hi, It is a little bit helpful to me, but it is not the solution of mine problem. Can you tell me how the code of PDF document will changed when you protected it(not copy, not edit, no print), or what is the principle how does it work. How PC recognize: this file is only to read, this can be copy, this cant be print etc.
Thanks

Calculating Interest on principle amount only

Hi all
I have set up the interest calculation configuration but I can't get the interest calculation to only calculate interest on the principle amount and not calculate interest on interest.
I have been able to do this in the selection parameters excluding the document type for interest - but I want to be able to specify interest calculation on the principle in the interest indicator configuration.
Can anyone help as to whether this can be done and if so where I can specify this in the IMG.
Thanks and regards

May be I am missing something, but the descriptive formula
Payable interest = (Total interest accrued to date - Any amount already payable) x Repaid amount / Outstanding amount before repayment
Does not seem to correlate with the formulas shown in the table.
Repayment number Interest accrued Ratio of amounts Payable interest
1 r1 A1
r1 x A1
2 r2 A2
r2 x (A2-r1A1)
I expected the formula to be as below.
Repayment number Interest accrued Ratio of amounts Payable interest
1 r1 A1
r1 x A1
2 r2 A2
(r2 - r1A1) x A2
Again, if you can provide a file with some sample values and expected results, that would clear things up.

How do you apply Single Responsibility principle to a repository

I am trying to apply "SOLID" whenever I can and try to use common sense and avoid a pattern when I see that a pattern is creating more problems than it's trying to solve. I don't want to apply a pattern and make life difficult for somebody else using
my code just for the sake "I write patterns" if you see what I mean.
Now I am struggling with one of the principles that I thought was the easiest to grasp: "SRP".
How do you practically apply this principle to repositories?
Let's suppose I have a
IEmployeeRepository
IUserRepository
IProductRepository
and commonly they will have methods like these:
public interface IUserRepository
User GetUser(int id);
IEnumerable<User> GetAllUser();
void DeleteUser(int id);
same for employees and products.
Are we saying that each of these method should be a class on it's own? even though at times we are talking a single line of code?

Hello,
"Are we saying that each of these method should be a class on it's own? even though at times we are talking a single line of code?"
interface is not a method. It has its own definition and you can refer to here:
http://msdn.microsoft.com/en-us/library/87d83y5b.aspx
Any from your question I think you may still confused about the usage of interface. In this way, I will recommend you have a look at the following blog:
http://www.codeproject.com/Articles/18743/Interfaces-in-C-For-Beginners
"Interfaces in C # provide a way to achieve runtime polymorphism. Using interfaces we can invoke functions from different classes through the same Interface reference, whereas using virtual functions we can invoke functions from different classes in
the same inheritance hierarchy through the same reference"
With the blog you can check that code to see details about how to use interface.

How to multiple/ parallel sets of books to generate more than one financial statement based on different (or the same) accounting principles.
My Client needs Parallel Ledger in SAP B1 similar like SAP ECC. Is this functionality available ?

Dear Mr. Nagrajan,
Thank you for your response. I have already gone through documents but not able to understand. Is there any setup for this ? or its just work around i.e. using template and special field in JV i.e. Ref. 1 /2
My doubts :
I understand that Chart of Account structure is one and common for IFRS and other accounting method. We need to create only those account separately ( 2 times with prefix like IFRS revenue account, GAAP Revenue account).
Now at time of entry, Assume some entries / adjustment are specifically for IFRS and not for other ledger. In this case, What need to do ?
You have mentioned about DTW approach but do we need to insert all JV's again with other ledger ?
Someone suggested that if any entry which are specific to IFRS Ledger, We need to user Ref.1 /2 column or Transcation code column and in which we can put IFRS
Based on this, Need to create 2 seperate template for IFRS and other ledger for all report.
This is my understanding of Solution in SAP B1. Please help me to clarify my though process
Please do needful.If you have done implemenation and if you can share doucment, it would be great help.

PI 7.4 Single Stack support for Principle Propagation SAML

Hi Folks,
Que: Does the single stack now support Principle Propagation using SAML?
The posts I have read so far conclude that SAML is only supported on the dual stack, not the single stack.
SAP Help gives steps for dual stack: Configuring Principal Propagation (SAML) - SAP Help Portal
This post from 2013 concludes no support for SAML in the single stack: PI 7.31 AEX - Principal Propagation
My time would better spent looking for an alternative solution for Principal Propagation rather than chasing something which is not supported (SAML on single stack).
Any help appreciated.

Message Routing Principles in PI 7.1

Hello Experts,
Please help me to understand what all message routing principle are available in PI 7.1. The one I a aware of is content based routing. Are there routing rules available??
- Rajan

Hi! Rajan,
I was little bit confused with ur question ?
Are you asking about Logical Routings ? If yes Logical Routings are nothing but Routing rules that you are defining means both Interface detmination and Receiver determination
Interface determination is rule which defines that you need to communicate via this particular XX interface and its corresponding
Receiver determination is also a rule which defines that you need to communiate with this Receiver Business System if there are more than one Business Components or SYstems based on the Rules and conditions that are giving in the editor.
Where exactly I was confused means ? I know only logica routings sicne this routing rules are for message processing only and henve are u calling this as Message routings rules ? or it is different from what I am saying correct me if I am wrong ? okay

What is principle difference between 'payment run' & 'payment lot'

Hello
what is principle difference between 'payment run' & 'payment lot' ?
by 'payment run' I understand all incoming payments and outgoing credits are settled
but doesn't payment lot also do that.
Thanks

Anshoo,
Payment Lot = Records Payments made in bulk.
Payment run = Too records Payments made in bulk
Difference
Payment lot = Usually u receive file from bank and post the items as a Lot <inbound file>
Payment run = U generate Payment run and send the file to the bank <outbound>
For Payment lot = Customer need not be on Direct Debit
For Payment run = Customer has to be on Direct Debit
For Payment lot = Payment can be thru chq/cash/cr card and Payment on account too can be posted
For Payment run = Payment is made only when the Customer is on DD and you cannot make payment unless there is either Open Invoice or BB line item
Hope this clears

BSEG-XINVE not specific to accounting principle

Hello gurus,
I need to reclassify invoices related with capital investments using the indicator BSEG-XINVE and the transaction FAGLF101.
My problem is that for some invoices there is a gap between the FR GAAP and IFRS rules:
-Case 1: Investment in both FR GAAP and IFRS (no problem)
-Case 2: Investment in only one accounting principle (problem)
I need to find a tool that will allow me reclassifying the invoice depending on the field BSEG-XINVE but also on the accounting principle.
Coukld you please help me finding a solution,
Thank you in advance for your help
Best regards
Pascal

Your problem is quite surprising
Let us go one by one...
1.what was the billing type?
2.Is it proforma--but with some configuration issues in VOFA(share the screen shot of VOFA for the problematic bill type)
3.As per you--once when you are releasing through VF02--No message/error--can you see accounting document for this Bill once after releasing(system cannot create accounting for ZERO value)
4.If you are releasing in VF02--then again why it will be visible in VFX3--update us..(RFBSK field in VBRK)
5.You are telling In case of VAT No-problem--CST is the problem--also i was confused by looking at your fourth point(if you are unable to see accounting document--how you came to know that this CST amount is actually sitting in allowed GL??)
6.Is your VAT & CST condition types using different tax codes???(additional Info)
7.do you Have the assignments of revenue account determination for your Bill type in VOFA??
Please update...

Accounting Principle role in Foreign Currency Valuation

Dear Frns,
Why do we create an Accounting Principle in Foreign Currency Valuation and assign the same to the Ledger Group.
Regards,
Venkata

Hi Venkata,
The Assignment of Accounting Principle to Ledger Group is to ensure that the system knows to which ledger group the valuation is to be done. Since we can valuate the foreign currency documents to ledger specific posting as well.
Say there is one ledger pertaining to Leading ledger 0L and another non leading ledger L1, where 0L is pertains to US GAAP and L1 pertains to IFRS. So based on requirement, during the execution of FAGL_FC_VAL, you specify valuation area which will post to those areas.
Hope this is clear.

Rithin

Accounting principle gap for fix asset

Dear all,
Our company has two accounting principle, for certain fix asset, local principle require it post to fix asset, depreciation will be posted to expense account and allocate to production order via cost center expense allocation in the month end. for group principle, it will be posted to A&D expense, not fix asset. this means that inventory cost and COGS are different.
We would like to generate two sets report for local goverment and group. does anyone has experience of this requirement? really appreciate if you share with me.
Rgds,
Ben

Hi,
For this kind of situation. you have different methods
1. Account solution
2. Ledger solution
3. Co Code solution
If you are using ECC5 or ECC6, you can have parallel ledgers (leading and non leading). If not you need to use Account solution that is you need to have diff depreciation areas and post accordingly.

HTTP_RESP_STATUS_CODE_NOT_OK when using Principle Propagation

Designing principle of auditing the DML on a specific table?

Hi All,
What is the designing principle of auditing the DML performed on a table? or a bunch of tables?
I know Oracle provides the auditing capability and there is Fine-Grained auditing available to use to keep track of row/column level changes.
However, in this case, since we want to keep all the changing history of the table, and we want to do it our own way, we don`t want to use the Oracle`s FGA.
the scenario is:
I have a table with 40 columns, and any one of them might be updated, including the primary key. (it sucks and bad)
we want to keep track of all the changes performed on this table, mainly DML.
the table structure I came up with is as below and it doesn`t look good or feel right.
So, could you share some experiences of how your design the table in this scenario? and the basic principle or rule to follow?
CREATE TABLE TBS (COL1 VARCHAR2(10), COL2 VARCHAR2(20), COL3 VARCHAR2(20), COL4 VARCHAR2(30)....., COL40 VARCHAR2(50));
CREATE TABLE tbs_audit (
SEQ_NUM NUMBER,
USER_NAME VARCHAR2(50),
UPD_DT TIMESTAMP,
OPERATION_TYPE VARCHAR2(20),
COL1_OLD_VAL VARCHAR2(10),
COL2_OLD_VAL VARCHAR2(20),
COL40_OLD_VAL VARCHAR2(50));Thanks in advance!

I would definitely put the auditing records into another table.
What I am struggling with is:
whether should I record the changed columns only or the whole row? to me, the first one is better. it saves space, and it comes easy when I want to display the changed history of certain columns.
And for the first one, should I use table structure like 1) or 2)? which one is better? why?
1)
CREATE TABLE tbs_audit (
SEQ_NUM NUMBER,
USER_NAME VARCHAR2(50),
UPD_DT TIMESTAMP,
OPERATION_TYPE VARCHAR2(20),
COL1_OLD_VAL VARCHAR2(10),
COL2_OLD_VAL VARCHAR2(20),
COL40_OLD_VAL VARCHAR2(50));
2)
CREATE TABLE tbs_audit (
SEQ_NUM NUMBER,
USER_NAME VARCHAR2(50),
UPD_DT TIMESTAMP,
OPERATION_TYPE VARCHAR2(20),
COL_name VARCHAR2(10),
COL_OLD_VAL VARCHAR2(20)
);

Basic Socket Server Principles

Hi - new to java, programming a socket server (working-ish) but not sure if the principles I am applying are appropriate.
Basically, during the course of development I decoupled the socket server application logic from the socket server itself so that I could develop them independently. To that ends I have two abstract classes; Server and Service (posted below).from which I derive concrete subclasses (SampleServer and SampleService). The basic idea is that the server handles connections and initializes a service instance. The service obtains the client socket connection, and proceeds to read/write as needed. When the service stops (for whatever reason, error or by accomplishing a goal), the server is supposed to close connections, and wait again for another client.
Thing is, I have no idea how efficient it is, or what best practice is. Of most concern is Server.run method (questions commented). Of almost equal concern is SampleService.doService(); In my experience, the client (I've been using a flash movie) seems to rarely recieve the entire stream of numbers.before the socket closes. I'd appreciate comments / criticisms / warnings / alternatives etc..
Thanks in advance.

Yeah, I've also used jpcap too...same problem because it wraps around WinPCap dll just like Wireshark/Ethereal. No lucks. I even tried Windump, same deal. It seems like so many of these sniffers are built as a wrapper around WinPCap dll so that might be the limiting factor.
However, I know this this is doable because I have had lucks using:
http://www.sstinc.com/winsock.html
But this product is only limited toward Windows OS. I would like to implement this into java so I can operate my application under windows, linux, unix, and mac.
Would you have any ideas how
SSTINC built their Winsock analyzer? I'm sure there has got to be a way to work around this....
Does anyone know if there is a Unix/Linux socket shim/analyzer out there? I'll have my boss buy it if java can not answer our problem.

What are the main COPA principles in manufacturing you need to know?

Hello
What are the main COPA principles in manufacturing you need to know?
thanks

Mr Comandante,
Which exactly is the information that you are looking for ?
It does not matter which strategy of manufacturing you are using. At the end of the period, the differences between the comparison of the planning costs with the actual costs can be taken to COPA, to be reflected as Inefficiency or differences in Production.
If you are using discrete (Make to order) or Process Manufacturing, you need to configure in the profile of the settlement of the order a profile for COPA.
If you are using repetitive manufacturing in the collector of cost.
Please feel free to ask for any further information that you want, mi estimado amigo

BI 4.0 Unable to Add principles to Users

Dear Experts,
We have a strange error with Business Objects 4.0 SP2 patch 6. when i am trying to Add users to any groups like Universe groups or Administrator group for adding the same i am getting into user security and add principles
when add principles page opened then i am able to see all the users in the list.
i select the user in Available users/Groups and if i need to add these users to selected users/groups pane, i am not able to see the Arrow mark to add the users to selected users/group Pane.
This is really giving lot of problem from past few days and unable to move further. we have also added latest service pack 6 on top of sp2. Did any of you faced this problem or know the solution for the same.

Hi,
no...never heared that case. I would recommend you open an OSS Message with the SAP Support. That sounds to strange!

Hi Alan,
You have three options when creating a Web page with the "Web Publishing Tool"; Snapshot, Monitor and Embedded. Snapshot and Monitor are simply including an image of the front panel in the HTML document, whereas Embedded actually embeds a VI front panel (not block diagram/code) with all its functionality in the HTML document to remote control the actual VI on the server. The technology used for the remote control communication is provided by the LabVIEW Runtime Engine. That is why the Runtime Engine has to be installed on the client machines to be able to see the Remote Panel.
When accessing the HTML document the first time, the front panel will be downloaded. After that point, only data that goes to and from the controls and indicators will be transferred. Since the image of the front panel is not repeatedly being transferred, you will get a much better result. One thing you have to take into account though, is that ALL data to and from the controls and indicators is being transferred through the TCP/IP connection, so if you are transferring a lot of data (for example one million points every second on a graph), your network connection can get flooded. Therefore, don't update the indicators with an amount of data that exceeds what can be shown on the indicator.
Does this make sense?
