All the key fields of a table must be stored together at the beginning of the table. A non-key field may not occur between two key fields.
A maximum of 16 key fields per table is permitted. The maximum length of the table key is 255.
If the key length is greater than 120, there are restrictions when transporting table entries. The key can only be specified up to a maximum of 120 places in a transport. If the key is larger than 120, table entries must be transported generically.

If you have more than one trigger that fires at the same time (for example "BEFORE INSERT OR UPDATE ... FOR EACH ROW"), ask yourself why you want or need 2 separate triggers, rather than one (which maybe calls two sparate procedures).

How many egift cards for one order?

I had emailed customer service asking how many egift cards could be used for one online order, and I was told you could use 5 per online order, and 10 in store. But then I saw this link in the customer service catagory, and it says you can use 10 gift cards per online order.

Can I use 5 or 10 gift cards for a online order? I have 7 $100 gift cards I want to use to make a online purchase. Thank you.

Hello stephanielynett,
Thank you for posting your concern on Best Buy Unboxed forum. Ready to use the e-gift cards that you have been saving from Birthdays and special occasions, and not sure on how many can be used in an order, can have an impact on how you place your order.
To the best of my knowledge, the most updated information is found on the link that you shared on this forum. You should be able to use to 10 e-gift cards per order.
Have a great day,

How many primary key fields allowed for one table?

hi,
when i creating a table , how many primary key fields are allowed for one table.
please any one give ans
thanks

Just checked it, Its 255, not 155. You can have as many key fields as you want, but you can not go over the 255 byte length for the total of all key fields. You will get a warning for over 120, as it says that there is limited functionality with a key over 120 in length.
Again, this is a total length of all key fields.

HOw many Depriciation Key we can have Maximum

HOw many Depriciation Key we can have Maximum

There is no hard and fast rule as to how many. Usually there are a number of keys that would post to FI/GL from depreciation area 01. Then there are other keys for tax/reporting purposes. Many are dependent on country specific requirements/laws.
The country specific charts of depreciation that are supplied by SAP contain the more common depreciation keys that are used. If you need to modify them, you should make a copy of the standard delivered key and then make your changes.

I have Final Cut Studio V1 - the PPC/Intel V5/5.1 cross-grade version, which would suit your requirements perfectly. (I have it for sale at present down here).
If you keep looking, you're sure to find a similar second hand copy in your area, without the need to upgrade your graphics card.
I'd go for Final Cut Pro as above over any version of Express. FCP has the full version of LiveType - not the truncated version that was released later on.

How many registration keys come with the new Final Cut Studio

Hi I'm thinking of buying the new final cut studio and am trying to find out how many registration keys come with the box. I have 2 others in the family that would use it on their comps as well, and my friend had gotten the previous version of final cut studio 2 (final cut pro 6) and said it came with 3 keys inside, which would be great for me. So I'm just making sure that's true. Thanks.
Also you can bring final cut pro 6 files from another computer onto a computer with final cut pro 7 and still work on them right?

Hello Gibbs,
Welcome to the forum.
Re: your question.
Your friend is a pathological lier (or delusional - sometimes it's hard to tell the difference).
FCP is licensed for one laptop and one desktop as long as:
1. Both machines are owned by YOU (your inlaws don't count as you)
and
2. They are not used at the same time.
If your family wants FCS, time for them to purchase their own copies. (Apple has dropped the price so low that even Junior High School students can afford their own copies now.)
Yes, FCP6 files will open without issue on FCP7. The reverse is not true.
Have fun.

How many mac-addresses a single port can store ?

How many mac-addresses a single port can store ?
And also what is the max limit for mac-addresses on a switch ?
Regards,
Chandu

Hi,
I don't think there is a limit per port.
The limit is the max number of entries in the CAM table so if for example the CAM table limit is 8000 and you already got 7200 entries you can have the 800 enties on different ports or on one port.

What is authorization object and how to create it for a table

Hi All,
What is authorization object and how to create it for a table?
Thanks

Hi
Authorization
For authorization checks, there are many ways of linking authorization objects with user actions in an SAP system. The following discusses three possibilities in the context of ABAP programming.
Authorization Check for Transactions
You can directly link authorization objects with transaction codes. You can enter values for the fields of an authorization object in the transaction maintenance. Before the transaction is executed, the system compares these values with the values in the user master record and only starts the transaction if the appropriate authorization exists.
Authorization Check for ABAP Programs
For ABAP programs, the two objects S_DEVELOP (program development and program execution) and S_PROGRAM (program maintenance) exist. They contains a field P_GROUP that is connected with the program attribute authorization group. Thus, you can assign users program-specific authorizations for individual ABAP programs.
Authorization Check in ABAP Programs
A more sophisticated, user-programmed authorization check is possible using the Authority-Check statement. It allows you to check the entries in the user master record for specific authorization objects against any other values. Therefore, if a transaction or program is not sufficiently protected or not every user that is authorized to use the program can also execute all the actions, this statement must be used.
AUTHORITY-CHECK OBJECT object
                        ID name1 FIELD f1
                        ID name2 FIELD f2
                        ID namen FIELD fn.
object is the name of an authorization object. With name1, name2 ... , and so on, you must list all fields of the authorization object object. With f1, f2 ... , and so on, you must specify the values that the system is to check against the entries in the relevant authorization of the user master record. The AUTHORITY-CHECK statement searches for the specified object in the user profile and checks the useru2019s authorizations for all values of f1, f2 ... . You can avoid checking a field name1, name2 ... by replacing FIELD f1 FIELD f2 with DUMMY.
After the FIELD addition, you can only specify an elementary field, not a selection table. However, there are function modules available that execute the AUTHORITY-CHECK statement for all values of selection tables. The AUTHORITY-CHECK statement is supported by a statement pattern.
Only if the user has all authorizations, is the return value sy-subrc of the AUTHORITY-CHECK statement set to 0. The most important return values are:
·        0: The user has an authorization for all specified values.
·        4: The user does not have the authorization.
·        8: The number of specified fields is incorrect.
·        12: The specified authorization object does not exist.
A list of all possible return values is available in the ABAP keyword documentation. The content of sy-subrc has to be closely examined to ascertain the result of the authorization check and react accordingly.
REPORT demo_authorithy_check.
PARAMETERS pa_carr LIKE sflight-carrid.
DATA wa_flights LIKE demo_focc.
AT SELECTION-SCREEN.
AUTHORITY-CHECK OBJECT 'S_CARRID'
                  ID 'CARRID' FIELD pa_carr
                  ID 'ACTVT' FIELD '03'.
IF sy-subrc = 4.
    MESSAGE e045(sabapdocu) WITH pa_carr.
ELSEIF sy-subrc <> 0.
    MESSAGE e184(sabapdocu) WITH text-010.
ENDIF.
START-OF-SELECTION.
SELECT carrid connid fldate seatsmax seatsocc
    FROM sflight
    INTO CORRESPONDING FIELDS OF wa_flights
    WHERE carrid = pa_carr.
    WRITE: / wa_flights-carrid,
             wa_flights-connid,
             wa_flights-fldate,
             wa_flights-seatsmax,
