Function and formula

Hello Gurus,
         for crystal report,  what is the difference between formula and custom function for returning value?
Many thanks,

I formula is developed within a report generally for one time use in a specific report. However, you can of course copy a formula from one report to another.
A Custom function effectively allows you to wrap up a commonly used formula into a function and then via a repository share it across multiple reports. However, you still need to use the custom function within a formula in a specific report.

  • Numbers' Functions and Formulas in Multiple Cells, Tables, and Sheets

    Hello,
    I'm stuck with specifics that center around usage, and I get the funny feeling I'm overlooking a simple detail or two.
    If I may, here goes.
    I'm working with a single spreadsheet that has several sheets within it, and each sheet has an identical table. Each table is used to record various data, and I use an additional table in a separate sheet to consolidate some of the information, so that I can track results, at a glimpse, by looking at averages, totals, etc.
    Each data table is organized for consolidation by tracking wins, ties, or losses. It is important to know that each data table only records a single win, tie, or loss along with its other applicable data. And on the actual consolidation table I am trying to tally specific data fields by the use of Numbers' functions and formulas, yet I wish to keep these tallied results organized by the determining factor of whether or not they were gathered from a table that recorded a win, a table that recorded a tie, or a table with a loss.
    To illustrate, each table contains data fields that record start time, finish time, elapsed time, the day of the week, etc. Let's say I have eight tables, and the first two are winning tables, three more are tables that record a tie, and the last three are losing tables. For example, on my consolidated data table I wish to enter a function and formula capturing which of the eight tables are wins, ties, and losses so that I can, at a glance, see how much time elapsed to obtain the wins, ties, and losses. So then, in this example, for wins I want to determine which of those wins took 20 minutes, or which of them took 15 minutes, etc. So then, out of the two wins, let's say both of them took 20 minutes each. I need the numeral 2 to be counted and recorded on the consolidation table since only two tables match the criteria. And I would do the same for all remaining data fields (e.g., start time, finish time, etc.). Just so long as everything is determined by wins, ties, and losses, and then organized by the respective data fields. Simply put, this example determines a total of two wins that meet the data field requirement of 20 minutes. Out of the eight tables (one table per sheet) any other wins would then be organized according to the specific data in the elapsed time data field on it's data table (e.g., 5 minutes, 15 minutes, etc.).
    The exact syntax structure of the functions and formula I'm unsuccessfully using follows below. It only seems to return a result of 1, and I think it is returning this value from the IF Statements. By the way, the Win, Tie, or Loss cell in each data table is cell formatted as a pop-up so I can either select None or 1. But in this example I'm basing this on the time period of 20 minutes, and out of the eight data tables I have two wins which also record the time period as 20 minutes, so I should see 2 and not 1 in the 20 minutes column of the consolidated data table. Also, I tried changing the syntax where I would type "=1" in the IF Statements, but it returned a result of =1, and if I don't include the equals sign and quotation marks the result just shows up as 1.
    My Syntax:
    IF(Trade 1::'Data Recorded (1)' '* Win', 1, IF(Trade 2::'Data Recorded (1)' '* Win',1, IF(Trade 3::'Data Recorded (1)' '* Win',1, IF(Trade 4::'Data Recorded (1)' '* Win',1, IF(Trade 5::'Data Recorded (1)' '* Win',1, IF(Trade 6::'Data Recorded (1)' '* Win',1, IF(Trade 7::'Data Recorded (1)' '* Win',1, IF(Trade 8::'Data Recorded (1)' '* Win',1, IF(COUNTIFS(Trade 1::'Data Recorded (1)' '* Time in Trade (in minutes)', "=20m")+COUNTIFS(Trade 2::'Data Recorded (1)' '* Time in Trade (in minutes)', "=20m")+COUNTIFS(Trade 3::'Data Recorded (1)' '* Time in Trade (in minutes)', "=20m")+COUNTIFS(Trade 4::'Data Recorded (1)' '* Time in Trade (in minutes)', "=20m")+COUNTIFS(Trade 5::'Data Recorded (1)' '* Time in Trade (in minutes)', "=20m")+COUNTIFS(Trade 6::'Data Recorded (1)' '* Time in Trade (in minutes)', "=20m")+COUNTIFS(Trade 7::'Data Recorded (1)' '* Time in Trade (in minutes)', "=20m")+COUNTIFS(Trade 8::'Data Recorded (1)' '* Time in Trade (in minutes)'))))))))))
    Please bear in mind that the COUNTIFS portion of the above syntax structure is something I'm already successfully using to count the totals of other things not mentioned above, and I'm hesitant to delete it since it already works to my satisfaction when I want to, for example, determine the total number of overall wins. So, just for illustration purposes, I might have an overall wins column in my consolidation table that records how many wins there are, regardless of organization by elapsed time, or any other data field. In other words, the COUNTIFS syntax structure already works to my satisfaction. I'm not sure if it's possible to alter it so that it isn't so long, but what's there does work just when counting total numbers, as just mentioned.
    In summary, I'm wondering which function I can use with the COUNTIFS function to determine which of my eight data tables are winning tables, but break those wins down further based on criteria like elapsed time, and in the above example the time elapsed is 20 minutes. As you may see above, I'm unsuccessfully using the IF function. Finally, I've looked at the function browser descriptions of things like LOOKUP, HLOOKUP, VLOOKUP, INTERSECT.RANGES, and a few others. And so far I haven't made good use of any of them the way I've done when I use the COUNTIFS function by itself when only counting overall totals. But now I must determine totals that meet certain criteria, as explained above.
    Please help if you dare (smile). This is a huge project I'm undertaking, and so as not to cause confusion I have not included all of the details. But rather, I've taken a small sampling and set it to the side for experimentation. If this small sample works out to my satisfaction I can simply copy and paste the syntax in all other respective cells in the consolidation table, changing only reference locations, and perhaps conditions or values. One thing is certain, I don't intend on giving up on it.
    Thank you for your time and advice.
    Blessings!

    Added image.

    I'd like to edit the last paragraph of my second posting, but for some reason an entirely new posting is being created when I attempt to do this. So when reading this post, please use it to replace only the last paragraph of my second post containing the four inserted images.
    Last paragraph begins:
    In closing, I need each cell in each column of each row in my consolidation table to remain as is. I have my reasons for doing this, and they all serve a specific purpose. The only exception would be the formatting of the last three rows as footer rows. Most importantly, and I should have made this abundantly clear earlier, my apologies, I need a single function and formula in cell E7 of my consolidation table that will firstly determine which data tables are winning tables while secondly and simultaneously counting which of those winning tables have elapsed times of 20 minutes. Perhaps, now this better explains why my syntax is written the way it is written. In the example I provided, if the proper function and formula were written it would result as 2 in cell E7 in my consolidation table. If there is anything else specific you need of me in order to assist me, please request it. Thank you.
    Last paragraph ends:
    Additionally, to t quinn:
    First off, thank you for returning to assist me. I really do appreciate your efforts. Please be aware that I'm avoiding going into details about each and every portion of my spreadsheet because I wish to avoid discussion that is off topic. As I stated earlier, I'm new to using these features of Numbers. My spreadsheet encompasses a much larger amount of data than I'm referring to in the example in my first post. But in my example I'm isolating just the information concerning what I'm now trying to accomplish to finish my spreadsheet project. Moreover, most of what I've done up to this point I was able to figure out on my own, or get help from watching videos on YouTube, or simply using the application help menu. Please be aware that I consulted all of these, repeatedly. I even contacted AppleCare, and was told this sort of support is not available. In spite of this, I've accomplished a great deal in my first large spreadsheet project. Please be aware that when I wrote my second post and specifically responded to you, I didn't want to be rude or ungrateful, and I still don't, but maybe the suggestions you and Hiroto made about gathering the count of wins, ties, and losses are something I've already done. I think I've done that separately. These counts are already in separate cells, and they are working fine. In my first post where I inserted only one image you can see examples of this in my consolidation table image, in cells B3 and E6. I apologize for not making this abundantly clear earlier. Furthermore, the portion of my syntax that shows the COUNTIFS is the exact way I accomplished this, and it is written the way it is written because I need separate sheets, each with their own data tables. Again, in cell E7 I need to determine which of the eight data tables that record wins are also recording 20 minutes, but I need this in a single function and formula with the result appearing only in cell E7. Once this is figured out I will adjust the syntax to do the same thing with every column (these are not shown but they exist) in my consolidation table for the last three footer rows, named Win Column Totals, Tie Column Totals, and Loss Column Totals. The last three rows being footer rows may not be necessary, and if so, I can convert them back to normal rows. Nonetheless, my consolidation table is counting the totals of all data in all data tables. This much I've already accomplished. Now I have one last function and formula I'm working on in order to determine which of the eight data tables record wins, ties, or losses while it simultaneously counts which of the wins, ties, or losses fall within certain categories like elapsed time, and this will be shown on my consolidation table only in the last three rows. Yes, I've gotten the total wins counted, and separately counted the total number of times 20 minutes was the elapsed time used, but so far, just looking at my consolidation table I don't know if the total number of times 20 minutes was used was with a win, tie, or loss. That's what I need to know now. Everything else is already accomplished. So then my consolidation table will show the totals for all data fields in my eight data tables as illustrated in cells B3 and E6. The last three rows of my consolidation table will break this down in a single function and formula with one row for wins, a second for ties, and a third for losses. And each of these respective last three rows will in the same function and formula determine if the win, tie, or loss also is one of the data fields in my eight data tables. How? By the use of columns in my consolidation table. Remember, each of my eight data tables are identical. In the example in my first post I only used one data field, elapsed time (Time in Trade), to illustrate in one column on my consolidation table what I'm trying to accomplish with all of the columns not shown in my consolidation table. Once this is figured out I can adjust it to complete the remainder of the consolidation table. Thank you, t quinn.
    To all reading this and attempting to offer assistance, if for any reason I'm still not explaining myself clearly, please continue to ask me more specific questions. I realize it's hard to communicate this way, and if Apple allowed us to upload the actual spreadsheet it would make this entire forum a better place to communicate. But that's going off topic, so let's simply focus on the matter at hand. Thank you.
    Blessings!

  • Function or formula to display the desired color in report

    Hi,
    I am using Web I rich client in BO XI R3.1 version and would like to know if there is any function or formula to display the desired color in report.
    I've used aleters but not getting the desired output. I need to display the color of some regions percentage wise based on a condition in a box i've created alerters for individual colors but they are not working.
    I came to know in crystal it is available just want to know if it is available in BO too.
    For more information about the issue am facing which had already posted in this forum please have a look in the below post.

    Posted: Mar 15, 2010 1:29 PM  Eswar Rao
    I am desperately looking for solution and trying to resolve this issue. I would really appreciate for your ideas or solutions.
    Thanks,
    Eswar

    Or just make one alerter. Make sure you are in the cell and open Alerters. Create one that says "Filtered Object or cell" = "Cell Contents"  "Less than" and enter the lowest number, like 0.6. Then click format and change to the color text or background you want. Say ok to all of that and make sure it works.
    Then edit the same alerter, click add sub-alerter. Make this one "Filtered Object or cell" = "Cell Contents" again, and put Operator of "Greater than or Equal" to 0.7. Then click on the plus sign button to the right and it should give you an "And" option. Make that one "Cell Contents" "Less than" 0.8. Again go into Format and change to the next color you want. Click OK all the way out and check.
    Then edit it again, and add another sub-alerter and make this one "Cell Contents" "Greater than or equal to" 0.9. and again format the color, and save.
    Does that not work?

  • Gamma function in formula node

    I am running LabView V.6.1 and try to use the gamma function in a formula node.
    According to the HELP text ''Formula Node and Expression Node Functions'', the syntax for the Gamma funtion is gamma(x), but this leads to the block diagram error ''Formula node: Undefined variable''.
    Other functions (like exp(x), sqrt(x) etc.) work.
    Thanks for helping.

    Hi,
    we ran into this one a little while ago. The help is a little misleading. The Gamma function actually only works with the Expression Nodes, and not the Formula nodes.
    Go to the labview help file, and search for "Differences Between the Parser in the Mathematics VIs and the Formula Node "
    Also refer to the following link for a bit more information :

  • Formula function in formula of type Rate Value Calculation does not work

    Hi,
    We are trying to prorate eligible salary based on some business rules.
    We have defined Standard rates with calculation method as 'Calculate for Enrollment Rule' and attached a formula in the 'Value Rule' field.
    Now inside the formula, if i directly return a value like 'Return 9000' , it works correctly. However, if i have a fomrula function and return the value as follows,
    l_value = CUSTOM_FF_FUNCTION()
    retunr l_value
    it does not return value.
    I have attached a package function that simply returns 4000 just for debugging.
    Even this does not return the value back to the formula
    Any pointers will be useful
    Thanks,
    LN

    Sorry. I had not checked this post earlier.
    We had 2 functions with same name and same contexts on the same database. Each of the functions called a separate package function and had its own logic.
    So sometimes the first function was called.At some other times, the second function was called.
    We deleted one of the functions and the formula worked well.

    Since installing LTR 5.4, which I've now upgraded to 5.6, I've encountered repeated slowness and malfunctions in operations, especially when using the Compare View function and the Tab key to open and close the right and left side panels.  Such problems never arose during two years of using LTR-4 and nothing else has changed on my computer.  I have a pretty simple system with only a few plug-ins, which are usually not in operation.  I have 12GB of RAM in my Windows 7 PC.  I could illustrate these problems with screen shots if you would tell me how to submit screen shots.  Otherwise I will try to describe the problems in words.
    The problem is clearly cumulative, growing worse as usage time passes.  Compare View feature gradually slows down and eventually seems to choke as my work session proceeds. If I Exit LTR and re-enter and start all over, things will work normally for maybe 30 minutes, but then the Compare View feature begins to become very slow to respond.   In a recent example with my screen full of thumbnails in Library mode I highlighted two images to compare. LTR started to open the Compare View screen by first having the top row of thumbnails disappear to be replaced by the "SELECT" and "CANDIDATE" words in their spaces  (but no images), but Compare View never succeeded in gaining control of the screen. After some seconds the top row of thumbnails reasserted its position and the Compare View windows disappeared. But LTR kept trying to bring them back. Again the top row of thumbnails would go away, Select and candidate would reappear, try again, and give up. This went on for at least 2-3 minutes before I tried to choose File and Exit, but even that did not initially want to respond. It doesn't like to accept other commands when it's trying to open Compare View. Finally it allowed me to exit.
    To experiment I created a new catalog of 1100 images.  After 30-40 minutes, the Compare View function began to operate very slowly. With left and right side panels visible and two thumbnails highlighted, hitting Compare View can take half a minute before the two mid-size  images open in their respective SELECT and CANDIDATE windows. When the side panels are open and two images are in the Select/Candidate spaces, hitting the Tab button to close the side panels produces a very delayed response--25-30 seconds to close them, a few more seconds to enlarge the two images to full size. To reverse the process (i.e., to recall the two side panels), hitting Tab would make the two sides of the screen go black for up to a minute, with no words visible. Eventually the info fields in the panels would open up.
    I also created a new user account and imported a folder of 160 images. After half an hour Compare View began mis-placing data.  (I have a screen shot to show this.)  CANDIDATE appears on the left side of SELECT, whereas it should be on the right. The accompanying camera exposure data appears almost entirely to the left of the mid-screen dividing line. Although the Candidate and Select headings were transposed, the image exposure data was not, but the data for the image on the right was almost entirely to the left of the line dividing the screen in two.
    Gurus in The Lightroom Forum have examined Task Manager data showing Processes running and Performance indicators and they see nothing wrong.  I could also send screen shots of this data.
    At this point, the only way I can process my images is to work 30-40 minutes and then shut down everything, exit, and re-start LTR.  This is not normal.  I hope you can find the cause, and then the solution.  If you would like to see my screen shots, tell me how to submit them.

    To experiment I created a new catalog of 1100 images.  After 30-40 minutes, the Compare View function began to operate very slowly. With left and right side panels visible and two thumbnails highlighted, hitting Compare View can take half a minute before the two mid-size  images open in their respective SELECT and CANDIDATE windows. When the side panels are open and two images are in the Select/Candidate spaces, hitting the Tab button to close the side panels produces a very delayed response--25-30 seconds to close them, a few more seconds to enlarge the two images to full size. To reverse the process (i.e., to recall the two side panels), hitting Tab would make the two sides of the screen go black for up to a minute, with no words visible. Eventually the info fields in the panels would open up.
    I also created a new user account and imported a folder of 160 images. After half an hour Compare View began mis-placing data.  (I have a screen shot to show this.)  CANDIDATE appears on the left side of SELECT, whereas it should be on the right. The accompanying camera exposure data appears almost entirely to the left of the mid-screen dividing line. Although the Candidate and Select headings were transposed, the image exposure data was not, but the data for the image on the right was almost entirely to the left of the line dividing the screen in two.
    Gurus in The Lightroom Forum have examined Task Manager data showing Processes running and Performance indicators and they see nothing wrong.  I could also send screen shots of this data.
    At this point, the only way I can process my images is to work 30-40 minutes and then shut down everything, exit, and re-start LTR.  This is not normal.  I hope you can find the cause, and then the solution.  If you would like to see my screen shots, tell me how to submit them.
