Why findByAltKey(String keyName, Key key, int) returns a RowIterator object
Hi All,
I was thinking that why findByAltKey(String keyName, Key key, int) returns a RowIterator object and not Row object because alternate key is a candidate key and is unique so only one record should be there for a particular alternate key.
Thanks
Puneet
findByKey (which you could also use) returns Row[]. findByAltKey is just a special version of findByKey that returns a RowIterator.
Probably it's not going to change for historical reasons.
Plus, the Key you use doesn't have to be a full key - it can be a partial one, meaning that you can match more than one row.

Primary Key Source returning improper value
Hi All,
I have a tabular updateable form.
My Primary Key field has
Primary key Source Type : Custom PL/SQL Function
Primary key Source : RETURN (EB_PACKAGE.GET_COD_NUM (:P4_CTY_TYPE));
My function is in a package and is executing properly and i have checked it.
I have an Item on that page as P4_CTY_TYPE whose value i'm passing to obtain the Primary key.
But my problem is the function does not return a proper value, i feel the value being passed for the function is always same. Why is proper value not being passed.
Hopefully I have explained my problem, if not let me know so.
Hoping for the solution.
Thanks n Regards
ArifHi Ravi,
Thanks for the reply and sorry for late reply.
The session value for P4_CTY_TYPE is ok.
P4_CTY_TYPE is a Select List with Submit.
I have a Report and there's a link which changes the value of P4_CTY_TYPE or can be changed by itself as it is a Select List.
Depending upon the value of P4_CTY_TYPE I'm displaying records in a Tabular form with Insert, Update and Delete facilities.
Now Suppose the Value for P4_CTY_TYPE is 10 at the start of the session then the function works fine and it always does for this value, when i select other value for P4_CTY_TYPE say 20. The value returned by my function is as if the parameter value being passed to the function EB_PACKAGE.GET_COD_NUM (:P4_CTY_TYPE)) is 10 and not 20. This is what i mean by function does not return a proper value.
If any more clarification required do let me know.
Thanks Once again.

Msg no.FF709 Error in account determination: table T030K key INT VS1 I0
Dear friends ,
We are trying to post a MIRO with tax code I0 for Brazil , but tax code I0 has only the AccKey VST activated in the tax code , but when we hit [Save] system is issuing the error message FF709-Error in account determination: table T030K key INT VS1 I0.
My question is: Why do we need to put the tax code I0 in the VS1 once we have only VST AccKey activated ?
We noticed that in the Main Program SAPLTAX1 and into Source code of LTAX1F02 , the system is doing a select single into T030K and issue this message.
We took a look into OSS notes but no relevant notes were found.
Best regards,
AlessandroHi,
The error message FF709 appears when for the account key and
tax code (e.g. V0) no G/L account was entered.
For account keys with the posting indicator = 2 (separate line item)
an G/L account HAS TO be maintained in OB40, also if it is a zero tax.
Only for account keys with the posting indicator = 3 (Distribute to
relevant expense/revenue items) like NVV no G/L account will be entered.
Best regards

Use special string as key of DES
I want to use a special string as key of DES.
I f I want to use a string which length is more than 8 as key,what should I do?
ThanksAlthough DES has been designed for using keys composed of eight 7-bit ASCII characters with parity (i.e., plain-text passwords), you do not need to use such "weak" keys. Common passwords have almost no "entropy" (i.e., random information); so you must not use passwords directly in any algorithm (DES, AES, RC4 etc.).
Remember - keys are not passwords; keys can be derived from passwords. Cryptographic algorithms usually use keys, not passwords.
The PBE algorithm (Password-Based Encryption) use passwords for encrypting, but do not use the passwords directly. It calculates a special function than derives a key from a password.
Study the PBE algorithm instead of trying to use the password as a key directly.
I will give an example to make you understand the problem better.
There is a class of functions called "cryptographic hashes" that works "digesting" the bytes you pass to it.
They receive any quantity of bytes as input, and return a fixed-size result (160 bits = 20 bytes for SHA-1, 128 bits = 16 bytes for MD5).
Examples of cryptographic hash are the MD5 and SHA-1 functions.
I will give several words that are very near in spelling, but their hashes are completely different.
The SHA-1 of "password" is 5BAA61E4 C9B93F3F 0682250B 6CF8331B 7EE68FD8
The SHA-1 of "passwords" is A267F7DB A707256B 0B664DEE 86AB9AE8 B4941218
The SHA-1 of "passwort" is 2E2B6533 A81BC154 30CF65DE 46DC097E EB5BA70C
The SHA-1 of "Password" is 8BE3C943 B1609FFF BFC51AAD 666D0A04 ADF83C9D
If you modify a byte in the content, the value is completely altered. You can see that the SHA-1 of "password" and "Password" are completely different.
The "naive" way of deriving a key from a password is simply to calculate the SHA-1 of the password, throwing out the unneeded bits (for instance, if you use DES, you can use only the first 8 bytes - 64 bits of the SHA-1 value.)
The PBE algorithm uses a more sofisticated and secure scheme but the inspiration is that you can derive a key from a password, and use the key to encrypt your data. -
Error in account determination: table T030K key INT MWS O1
Hi ,
I created billing document. now when i am posting to accounting. I am getting an error while posting to accounting .
" Error in account determination: table T030K key INT MWS O1
Please guide me.

AKiHi Akhilesh kumar,
System is looking for GL account for Tax line item....
In the error message, INT represents your chart of accounts and MWS shows for your transaction key assigned in your tax procedure. and O1 is tax code...
Maintain in OB40 or simply go to the T code FTXP and go to the tax code O1 and maintain the tax accoutns by selecting "tax accoutns " Tab button
Thanks & Regards

On a new MacBook Air I'm using the Ukelele key layout for Devanagari to map Dvorak. But when I was on the Aluminum 3G I was able to only switch the "DELETE" key with the "RETURN" key through the system somewhere. Ukelele has maybe updated itself and I was able to switch them there. But the end result is that both keys act as a "DELETE" key. That seems to mean that the "RETURN" key was changed properly but the "DELETE" key cannot be changed.
I found "KeyRemap4MacBook" so I downloaded and Installed it. It did not offer the switch I need. So on the forum I found "DoubleCommand" and still could not make it do what I wanted.
Then the system crashed for the first time and shut itself down. On restart the keyboard didn't function. I uninstalled "KeyRemap4MacBook" and still it was not working. (try typing your password when the key layout is not functioning) Then I uninstalled "DoubleCommand" and on restart my keyboard works!
Anyone have any ideas for remapping the "DELETE" key to "RETURN" ?You cannot do that with UKELELE, because this beautiful app does not change system settings. You have two ways to deal with this:
1. Apple’s settings in System Preferences / Keyboard / Modifer Keys
2. and / or install a pretty utility called DoubleCommand, free. This one can offer many settings. I use it for changing right Enter key on my MacBook into Option key, just because I use many keybaord layouts, and also need dead keys very frequently.
Give a try, you will be satisfied. -

How do I know if I can convert a String value to an int value or not?
Hi,
I want to know how to make the judgment that if I can convert a String value to an int value or not? Assume that I don't know the String is number or letters
Thank youEncephalopathic wrote
Again, why?One of the problems (have been dued) in my codelab asks us to write a class as follow
Write a class definition of a class named 'Value' with the following:
a constructor accepting a single integer paramter
a constructor with no parameters
a method 'setVal' that accepts a single parameter,
a boolean method, 'wasModified' that returns true if setVal was ever called for the object.
a method 'getVal' that returns an integer value as follows: if setVal has ever been called, it getVal returns the last value passed to setVal. Otherwise if the "single int parameter" constructor was used to create the object, getVal returns the value passed to that constructor. Otherwise getVal returns 0.
The setVal(int y) returns nothing, so how do I know whether it has been called or not?
