How to avoid same entry in numbers

I am using a numbers file to organize my client. However, I entered one client more than one time. How can I avoid making the same entry / alert for entering the same entry?
Is there any solution?
Thanks for mac fans support

Assuming your list is in column B, then in a cell in another column, enter this formula:
=IFERROR(VLOOKUP(INDEX(B,COUNTA(B)+ROW(B)-1),OFFSET(INDIRECT(ADDRESS(ROW(B),COLU MN(B))),0,0,COUNTA(B)-1),1,FALSE),"No Duplicate")
This formula alerts you if the last item in the list was already entered. Note, it only checks the last item in the list, so if the list has 10 entries and 2 and 3 are duplicates, this formula will not alert you.
I also added a Conditional Format to make it more apparent when the value of the formula cell changed.

I didn't know how many header rows you had, so this formula is slightly more complicated to account for any number of header rows. If this formula doesn't help, just post more info. I'm sure someone can help.

How to avoid duplicate BOM Item Numbers?

Hello,
is there a way to avoid duplicate BOM Item Numbers (STPO-POSNR) within one BOM?
For Routings I could avoid duplicate Operation/Activity Numbers with transaction OP46 by setting T412-FLG_CHK = 'X' for Task List Check. Is there an aquivalent for BOMs?

I see people from different ages at my work and every month I need to count how many people from each age I've seen that month. How can I do to give the entries to numbers in a single cell and make numbers count them for me?

I see people from different ages at my work and every month I need to count how many people from each age I've seen that month. How can I do to give the entries to numbers in a single cell and make numbers count them for me? The final result would be a spreadsheet telling there were 8 people from 20 to 39 years old, 14 peolple from 40 to 59 and so on...

This appears to be an 'input form' using 'Radio Buttons' to select the category. Neither of these features are supported in Numbers '09.
You can input the data on one table and summarize it on a second table, but the input table will continue to hold data for each event.
And by using the Reorganize button, you can hide all but two rows of that table to approximate the appearance and performance of an input form.
Here are the two tables, Data on the left and Summary on the right. Notes below.
The grey-filled columns in both tables are 'working' columns, and may be hidden (as shown in the image below).
Data table:
D1 contains the word "TRUE" (in capital letters). (This row is always shown.)
D2 is empty, or may contain any value except "TRUE" (This row is always hidden under the Reorganize rule.)The rest of Row 2 of this table requires the data shown: a number outside the range to be counted (999), and two checkboxes, both checked.
D3 (and filled down the rest of column D): =AND(OR(B2,C2),NOT(OR(B3,C3)))
The formula returns TRUE only for the first unused row in the table (ie. the first row for which neither checkbox has been checked)
Summary table:
Column A contains labels for the age ranges to be counted.
Column B contains the same information in the form necessary for the formulas in columns C and D. They need a numeric value, and that value must be the largest acceptable value in the range to be counted.
C2 (and filled right to column D, then both filled down to row 5):
=COUNTIFS(Data :: $A,"<="&$B,Data :: B,TRUE)-SUM(C$1:C1)
Two changes from the previous example:
COUNTIFS is used to separate the Native and Foreign counts as well as the age range to be counted.
The amount subtracted from each result is the SUM of the earlier results, and includes the text value in the first cell of the column (which is interpreted by SUM as a zero).
See note below regarding my earlier formula.
When the greyed columns are hidden and the checkbox in the Reorganize pane is checked, the two tables will appear as shown below:
Close the reorganize pane, and the 'data entry form' is ready to use.
To use, enter the age first, then check one of the boxes.
As soon as one box is checked, the row will be hidden, and the next (unused) row will be shown.
Regards,
Barry
Note regarding formula in my earlier post:
The earlier formula will give erroneous results as it subtracts only the count directly above it from its count of persons in the age range 0-n.
In E2 of that table, replace "-E1" with "-SUM(E1:E$1)
Fill down to E8.
Ignore the instructions (in that post) following "Fill down to E8."

How do I edit or enter values on multiple sheets at the same time in Numbers? I can do it in Excel but I don't the procedure in Numbers. Thank you!

The only I way I can think of to modify a single value and have that value change in multipl locations is to have all "the other places" reference a single cell. There is not way without a referene to modify a set of cells simulateously.
This may be something like what you want:
Enter a value in the table "Original Data" cell A1 and the A1 cells of tables Ref1, Ref2 and Ref2-1 will change

Hi,

Thanks,

If you disconnect the cable going to the serial device, do you still get the echo? If so you have something going on in the port setup. If disconnecting the cable stops the echo then the device you're talking to is doing it - which would be my bet. One thing to check is whether this might not be normal operation. I have seen devices that if a command was successful, it simply echo'd back the command string you had sent. Also many serial devices have setting for specifying whether they are to echo commands.

Address book has same entries multiple times how can I go back to original cesium

Address book has same entries multiple times how can I go back to original cesium

After a couple of days, I'm noticing that the repeat(ing) offenders have more than 10 episodes, and seem to keep repeating them every time I sync.
They only show once in my phone and in the iTunes Podcasts, but through iTunes and looking at what's in my phone is when I see the repeats.
Even after I've marked a podcast as played, and deleted it from within my phone, as well as telling iTunes to delete the played episodes, it still shows multiples of the played episodes.
There doesn't seem to be any rhyme or reason to it either. They aren't the newest ones either.

How to avoid multiple listing for same artist?

How to avoid multiple listing for same artist?

Sounds like there might be blanks in the artist name.
For instance "Lou Reed" and "Lou Reed_" will not match.
(Pretend the underscore _ is a blank).
Select all the Lou Reed songs, Get Info, and type "Lou Reed" in the artist field. That should fix it.

Order entry cut off time to avoide same day line itme confirmation

Hello Friends,
We have a very unique requirement as below u2013
Business want SAP System to automatically determine the Order entry cut off time to avoid same day line item confirmation. I.e. If an order is entered after a specific time in a day (For example if order is entered after 2 PM local time) system should not confirm that order on the same day. In such cases system should confirm the schedule line for that line item on the next day.
Requesting you kindly guide us if there is something we can do in SAP to achieve this.
Thanks and Best Regards,
Amol Wadekar.

Hi,
check the Rounding Work days in the shipping point customizing.
"Rounding-up period for delivery scheduling (in days)

How to avoid the message in the dashboard report

Hi,
I am developing Dashboard reports(graphs) using WAD. Query and WAD are working fine. I need to put a variable for Calendar Month or Year in the graph .I am populating the Variable with default value initially and I am getting the correct result . But if I change the Variable value second time, I am getting a message (type I(information) ) in the same screen which says that 'You cannot change variable ZCALYEAR_WT01 for charact. 0CALYEAR during query navigation' . And below is the detailed information about the error message.
The Can be changed in query navigation property has been set for variable ZCALYEAR_WT01, characteristic 0CALYEAR. However, the variable is used in the query in such a way, that the system is unable to apply this change-option.
This can, for example, occur under the following conditions:
Characteristic 0CALYEAR is filtered by additional restrictions (the restrictions must be joined using an OR-connection)
A second characteristic, which is restricted by a variable, is compounded to charcteristic 0CALYEAR.
Variable ZCALYEAR_WT01 is a hierarchy node variable, but the hierarchy has not been determined uniquely.
A variable can be changed during query navigation only if it is used exclusively in a drilldown-characteristic, and there are no further restrictions to the characteristic other than this variable. There must be no additional characteristics with variables compounded to the characteristic you are working with. For variables for hierarchy nodes, the hierarchy must be determined uniquely and agree with the set display hierarchy.
Also, if the characteristic value is moved, for example (ZCALYEAR_WT01 - 1), the variable is no longer able to be changed when navigating queries.
System Response
The entry ZCALYEAR_WT01 Can be changed during query navigation is not applied.
Procedure
I checked the query definition and it is not having any offset or any other restrictions for Calendar Year
It is used for finding the total quantity by country for the year .Hence Quantity keyfigure is added in the Keyfigures and Country is in the Rows and Calendar Year is restricted with Variable in the global filter .There are no other fields and no other restrictions .
I am still trying to figure out why the warning apprears in the DashBoard. Since this Dashboard report will be used by the Power users and this warning message will be annoying to them .Hence I need to find how to avoid this message.
Kindly do let me if anyone has faced this and solved earlier.
Thanks for your time.
Thanks & Regards,
Raja

Hi Nick,
Thanks for your suggestion and it worked for me I added the 'System message' web item and set the visibility to 'Hidden' .Now I am not getting any message. Thank you for both.

LD_ASSUME_KERNEL does not work in recent distros. How to avoid?

LD_ASSUME_KERNEL=2.4.XX does not work in all recent distros.
$ export LD_ASSUME_KERNEL=2.4.20
$ ls
ls: error while loading shared libraries: librt.so.1: cannot open shared object
EBS contains very old cmponents like MWA wich not compiled without this setting. How to avoid errors?

You can unset LD_ASSUME_KERNEL and EBS 11i (11.5.9 and 11.5.10) will work fine on 2.6.16 kernels (SLES-10 and RH 5.0).
The following instructions should get you going:
1) Setup the environment as you would for running Applications on RH 4 or SLES9
I.E. follow Oracle Applications Installation Update Notes, Release 11i (11.5.10.2)
http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=316806.1
2) Remove any LD_ASSUME_KERNEL references in O/S /etc/profile.d files
3) Comment out LD_ASSUME_KERNEL entries in $ORACLE_HOME/appsutil/bin/adgetlnxver.sh and $AD_TOP/bin/adgetlnxver.sh
if [ ${setflag}x = "x" -a $os = "Suse" ]; then
# LD_ASSUME_KERNEL="2.4.21"
# export LD_ASSUME_KERNEL
     os="Suse"
fi
if [ ${setflag}x = "x" -a $os = "RH" ]; then
# LD_ASSUME_KERNEL="2.4.19"
# export LD_ASSUME_KERNEL
     os = "RH"
fi
If doing a rapid install, the database startup will fail and rapidwiz will prompt to ignore or retry. At this point, edit $ORACLE_HOME/appsutil/bin/adgetlnxver.sh as shown above and click on retry. It will then run to the autoconfig step at the end and error out. Just hit cancel, edit $AD_TOP/bin/adgetlnxver.sh and run autoconfig.
On Suse, one needs compat-gdbm for libgdbm.so.2
rpm -Uhv compat-gdbm-1.8.0-7.i586.rpm
Preparing... ########################################### [100%]
1:compat-gdbm ########################################### [100%]
Also in /usr/lib run ln -s libdb.so.2 libdb.so.3
Ref:
Note:300807.1 for Suse
create symbolic link called libdb.so.2 pointing to libdb.so.3, as follows:
$ cd /usr/lib
$ ln -s libdb.so.3 libdb.so.2 (or install db1-1.85-85.1 which does the same)
Note:294043.1 for Red Hat
As per an internal Bug 4045349, this is an issue with O/S side installation of compat-db rpm.
libdb.so.3 gets installed when compat-db rpm is installed.
- The O/S installation CD would contain compat-db
e.g compat-db-4.1.25-6.i386.rpm ( may change as per your version ).
- Manually install the compat-db rpm
e..g "rpm -ivh compat-db-4.1.25-6.i386.rpm"
OR
Note:345172.1
A library is missing: libdb.so.2 is from gnome-libs-1.4.1.2.90-34.1.i386.
This error also occurs in SLES9, same cause, slightly different resolution. SLES9 comes with libdb.so.3 and libdb.so.4 but not libdb.so.2 - need to install db1-1.85-85.1 to get libdb.so.2.
4) In order to relink cplex library executables (MSC, MSO, MSR, MST, WIP, etc), edit $AD_TOP/bin/adrelinknew.sh and add the following LD option (-Wl,--noinhibit-exec) in the LINUX section:

LDFLAGS='-s -L$(ORACLE_HOME)/lib -L$(ORACLE_HOME)/lib/stubs -ldl'

After this chance, you can apply any MRP, ASCP patch and all executables will relink correctly. You can also use adadmin to relink all executables and it completes without error.

How to avoid XVBPA line item values while creating sales order

Hi Friends
I am creating Sales order using function module IDOC_INPUT_ORDERS, for that I am passing partner details through segment E1EDKA1.If I pass the same partner details(Partner number, name1,name4,city,postel code) which is same like customer master,
I can able to book the order and entries are coming only one time in VBPA table(Header Item level).But if I change any value for the particular partner in the Input(For example Name4, there is no value in customer master but I added through program).Now its creating an order but its showing the entered partner informations in header level.When I checked the same in line item level, its not picking the values from header, its picking the values from customer master for that particular partner.
So this line item also coming in VBPA table, because its different from header data.
Anyone guide me, how to avoid this problem while booking order through program.
Thanks
Gowrishankar

I am updating Ship-To-Party value in segment E1EDKA1 and calling IDOC_INPUT_ORDERS function module to create the sales order.
In this case for the particular partner there is no NAME4 value in KNA1, I am passing some value through this segment E1EDKA1.
So its creating an order with this new addresses , so its generating new ADRNR in VBPA header level.Thats fine.But the same time
its not copying the same value from header to line item.
In Line item level again its picking the address details from KNA1 for the particular partner number.So its showing Blank value in NAME4 field of line items.Its creating and spllitting issue, while creating delivery.
Thanks
Gowrishankar

Hi
these are the performance tips
Instead of using nested Select loops it is often better to use subqueries.
SELECT * FROM SPFLI
INTO TABLE T_SPFLI
WHERE CITYFROM = 'FRANKFURT'
    AND CITYTO = 'NEW YORK'.
SELECT * FROM SFLIGHT AS F
    INTO SFLIGHT_WA
    FOR ALL ENTRIES IN T_SPFLI
    WHERE SEATSOCC < F~SEATSMAX
      AND CARRID = T_SPFLI-CARRID
      AND CONNID = T_SPFLI-CONNID
      AND FLDATE BETWEEN '19990101' AND '19990331'.
ENDSELECT.
The above mentioned code can be even more optimized by using subqueries instead of for all entries.
SELECT * FROM SFLIGHT AS F INTO SFLIGHT_WA
    WHERE SEATSOCC < F~SEATSMAX
      AND EXISTS ( SELECT * FROM SPFLI
                     WHERE CARRID = F~CARRID
                       AND CONNID = F~CONNID
                       AND CITYFROM = 'FRANKFURT'
                       AND CITYTO = 'NEW YORK' )
      AND FLDATE BETWEEN '19990101' AND '19990331'.
ENDSELECT.
<b>Internal Tables</b>
1.     Table operations should be done using explicit work areas rather than via header lines.
2.     Always try to use binary search instead of linear search. But dont forget to sort your internal table before that.
3.     A dynamic key access is slower than a static one, since the key specification must be evaluated at runtime.
4.     A binary search using secondary index takes considerably less time.
5.     LOOP ... WHERE is faster than LOOP/CHECK because LOOP ... WHERE evaluates the specified condition internally.
6.     Modifying selected components using MODIFY itab TRANSPORTING f1 f2.. accelerates the task of updating a line of an internal table.
Point # 2
READ TABLE ITAB INTO WA WITH KEY K = 'X BINARY SEARCH.
IS MUCH FASTER THAN USING
READ TABLE ITAB INTO WA WITH KEY K = 'X'.
If TAB has n entries, linear search runs in O( n ) time, whereas binary search takes only O( log2( n ) ).
Point # 3
READ TABLE ITAB INTO WA WITH KEY K = 'X'. IS FASTER THAN USING
READ TABLE ITAB INTO WA WITH KEY (NAME) = 'X'.
Point # 5
LOOP AT ITAB INTO WA WHERE K = 'X'.
ENDLOOP.
The above code is much faster than using
LOOP AT ITAB INTO WA.
CHECK WA-K = 'X'.
ENDLOOP.
Point # 6
WA-DATE = SY-DATUM.
MODIFY ITAB FROM WA INDEX 1 TRANSPORTING DATE.
The above code is more optimized as compared to
WA-DATE = SY-DATUM.
MODIFY ITAB FROM WA INDEX 1.
7.     Accessing the table entries directly in a "LOOP ... ASSIGNING ..." accelerates the task of updating a set of lines of an internal table considerably
8.    If collect semantics is required, it is always better to use to COLLECT rather than READ BINARY and then ADD.
9.    "APPEND LINES OF itab1 TO itab2" accelerates the task of appending a table to another table considerably as compared to LOOP-APPEND-ENDLOOP.
10.   DELETE ADJACENT DUPLICATES accelerates the task of deleting duplicate entries considerably as compared to READ-LOOP-DELETE-ENDLOOP.
11.   "DELETE itab FROM ... TO ..." accelerates the task of deleting a sequence of lines considerably as compared to DO -DELETE-ENDDO.
Point # 7
Modifying selected components only makes the program faster as compared to Modifying all lines completely.
e.g,
LOOP AT ITAB ASSIGNING <WA>.
I = SY-TABIX MOD 2.
IF I = 0.
    <WA>-FLAG = 'X'.
ENDIF.
ENDLOOP.
The above code works faster as compared to
LOOP AT ITAB INTO WA.
I = SY-TABIX MOD 2.
IF I = 0.
    WA-FLAG = 'X'.
    MODIFY ITAB FROM WA.
ENDIF.
ENDLOOP.
Point # 8
LOOP AT ITAB1 INTO WA1.
READ TABLE ITAB2 INTO WA2 WITH KEY K = WA1-K BINARY SEARCH.
IF SY-SUBRC = 0.
    ADD: WA1-VAL1 TO WA2-VAL1,
         WA1-VAL2 TO WA2-VAL2.
    MODIFY ITAB2 FROM WA2 INDEX SY-TABIX TRANSPORTING VAL1 VAL2.
ELSE.
    INSERT WA1 INTO ITAB2 INDEX SY-TABIX.
ENDIF.
ENDLOOP.
The above code uses BINARY SEARCH for collect semantics. READ BINARY runs in O( log2(n) ) time. The above piece of code can be more optimized by
LOOP AT ITAB1 INTO WA.
COLLECT WA INTO ITAB2.
ENDLOOP.
SORT ITAB2 BY K.
COLLECT, however, uses a hash algorithm and is therefore independent
of the number of entries (i.e. O(1)) .
Point # 9
APPEND LINES OF ITAB1 TO ITAB2.
This is more optimized as compared to
LOOP AT ITAB1 INTO WA.
APPEND WA TO ITAB2.
ENDLOOP.
Point # 10
DELETE ADJACENT DUPLICATES FROM ITAB COMPARING K.
This is much more optimized as compared to
READ TABLE ITAB INDEX 1 INTO PREV_LINE.
LOOP AT ITAB FROM 2 INTO WA.
IF WA = PREV_LINE.
    DELETE ITAB.
ELSE.
    PREV_LINE = WA.
ENDIF.
ENDLOOP.
Point # 11
DELETE ITAB FROM 450 TO 550.
This is much more optimized as compared to
DO 101 TIMES.
DELETE ITAB INDEX 450.
ENDDO.
12.   Copying internal tables by using ITAB2[ ] = ITAB1[ ] as compared to LOOP-APPEND-ENDLOOP.
13.   Specify the sort key as restrictively as possible to run the program faster.
Point # 12
ITAB2[] = ITAB1[].
This is much more optimized as compared to
REFRESH ITAB2.
LOOP AT ITAB1 INTO WA.
APPEND WA TO ITAB2.
ENDLOOP.
Point # 13
SORT ITAB BY K. makes the program runs faster as compared to SORT ITAB.
Internal Tables         contd
Hashed and Sorted tables
1.     For single read access hashed tables are more optimized as compared to sorted tables.
2.      For partial sequential access sorted tables are more optimized as compared to hashed tables
Hashed And Sorted Tables
Point # 1
Consider the following example where HTAB is a hashed table and STAB is a sorted table
DO 250 TIMES.
N = 4 * SY-INDEX.
READ TABLE HTAB INTO WA WITH TABLE KEY K = N.
IF SY-SUBRC = 0.
ENDIF.
ENDDO.
This runs faster for single read access as compared to the following same code for sorted table
DO 250 TIMES.
N = 4 * SY-INDEX.
READ TABLE STAB INTO WA WITH TABLE KEY K = N.
IF SY-SUBRC = 0.
ENDIF.
ENDDO.
Point # 2
Similarly for Partial Sequential access the STAB runs faster as compared to HTAB
LOOP AT STAB INTO WA WHERE K = SUBKEY.
ENDLOOP.
This runs faster as compared to
LOOP AT HTAB INTO WA WHERE K = SUBKEY.
ENDLOOP.
