Coverage profile and Stime period profile in MRP

Can anyone explain what is the importance of coverage profile and safety time period profile in MRP2 view and what is their implication in MRP and SOP ?

Hi,
Coverage profile is used in Material Requirements Planning for calculation of dynamic safety stock. This dynamic safety stock is calculated by using formula: Average daily req*range of coverage.
Average daily req is calculated by considering requirements in specific periods and no of days for the total period length.
You can find all the setting in
MRP--> Planning-> MRP Calculation---->Define range of coverage profile.
e.g.
You have maintained in coverage profile:
Period indicator: W(week)
Number of periods to be considered for ADR: 2
Period length: Standard days (5 days)
Range of coverage: 5 days
Req for 1st week: 1000
Req for 2nd week: 1000
then Ave daily req.= (1000+1000)/(5 period length*2 no. of periods)=200
then Dynamic safety stock= 200 (ADR)*  5(range of coverage)=1000
Hope you got it.

  • How to use Device Profiles and Viewing Conditions Profile in Photoshop Elements 11?

    In trying to get to grips with the Colour management aspects of PSE11, I have encountered the following problems:
    Having selected "Display" a sequence of clicks (Change display settings -> Advanced settings -> Colour Management -> Colour Management tab -> Colour Management)
    gives a screen which includes the headings:
    Device Profile  and Viewing Conditions Profile.
    1. Device Profile. Besides sRGB and ARGB, the profile list includes the profiles for all of the Epson papers. (I have an Epson Stylus Photo PX810FW).
    I changed the Profile to an Epson Grayscale, this was accepted within the menu, but there are no changes from normal when I viewed the image on the Windows screen or within
    PSE11. ("normal" is sRGB or ARGB).
    I thought it worth a try to test that, if I wanted the display image to closely represent what I would get on a particular Epson paper, this may be a way to do it.(I suspected this approach because I have never
    seen it in the literature!).
    So what is the purpose of all of the paper Profiles appearing in the Display listing?
    2. The Viewing Conditions Profile has also several options. I have tried to find the criteria for choosing one rather than the other, but failed to find any information. Can anyone help? I seek general guidance
    rather than the details of the Profiles.
    As a seperate question:
    Selecting Image on the PSE11 menu across the top of the displayed image, and then Convert Colour Profile, I tried this process on an image, converting tiff to sRGB. When saved there was an extra asterisk in the saved title but in this case,
    the file was still labelled tiff and there was no change in the number of Mbs. If a conversion has taken place, how is one to know?  Does saving a tiff file as jpeg change its colour profile? When is it useful to use this feature?
    Many thanks to all responders! 

    Addressing your second question, you are confusing two different things.
    tiff is an image file format, as is jpeg, as is psd, as is png, as are dozens (if not hundreds, http://en.wikipedia.org/wiki/Image_file_formats) of other formats.
    A colour profile represents the colour characteristics of devices so that, for example, displays know how to display the colours, printers know how to print them.
    Image files MAY, but do not have to, contain colour profiles.

  • PS CC Converting to profile and embedding a profile

    Hi,
    I just started using PS CC 2014. I have a number of variables that have changed, such as a new iMac, secondary monitor etc. I am working in aRGB when processing and I go to print via the Canon plug-in for Photoshop. I convert to profile using the ICC profile I want to use for the media and ink set that I am using. I had custom profiles made for these papers. When I save the file after printing it, it embeds the ICC profile, example Epson Premium Luster etc. instead of keeping it in the aRGB working space. I do not recall ever seeing this done automatically in prior versions and years that I have used PS. I would like to save the changes etc. but I do not want the paper profile embedded because I may want to use another paper with that file next time. When I open the file the next time and I want to print it I get the message that there is a mis-match between working profile and embedded profile, or something similar to that ( I do not have the message in front of me ). That means I have to convert the file to the working space at that point and it is an extra step that I did not have to do before.
    Is there a box I need to check or uncheck somewhere to keep the file in the aRGB space or am I just loosing my mind here?
    Thank you,
    Jim

    I'm not a Color Management expert, but converting and then saving from Adobe RGB to a Printer Profile tags and saves that file with that profile.
    Your file space, Adobe RGB, no longer matches Photoshop's Adobe RGB working space and that's why you get the warning.
    If you are printing from Photoshop, you do not convert to that profile and save, otherwise it is embedded.
    That would only make sense if the printer was somewhere else, and you would then make a copy of that file with that specific printer profile embedded.
    What you do is use the Print dialog and check "let Photoshop manage colors" and you pick your profile from the list.
    Your file stays tagged as Adobe RGB.
    You can turn off mismatch warnings in CC 2014  But be sure you are not "hiding a problem".

    Uncheck these boxes:

  • Installation of camera profiles and x-rite Profiles show up only in a certain folder of a catalogue

    Dear all,
    I'm working in a Maverics environment on which LR 5 is running. I've tried to install the camera profiles for the Nikon D800 by copying them to the users Library/Applicaton Support/Adobe/CameraRaw/Camera Profiles. After re-starting LR the profiles didn't show up. In a second attempt I tried to impoprt them with the extention manager which didn't work.
    The second problem I'm facing is, that I've created camera profiles with x-rite. The profiles show up only in a certain folder in LR in the same catalogue. This means in this certain folder named shootings i can choose the x-rite porfiles. When I go -without leaving the catalogue- to an other folder ie. named sports, I can not see the profiles.
    It would be great if somebody has a useful idea
    Thank you very much in advance.
    Cheers Stefan

    See the instruction below for the location where your profiles should be placed. If they are placed in the same folder where Lightroom install package places the profiles created by Adobe they will not be recognized.
    Your custom Camera Raw & Lens Profiles should be installed to the User folders…
    Lightroom 5 no longer uses the shared ProgramData (Windows) / Application Support (Mac) folders for Camera or Lens Profiles. Instead, it stores the built-in profiles with its program files.
    When you create camera or lens profiles, they must be stored in the user locations listed below. If you previously stored custom profiles in other locations, you’ll need to move them to these user folders, otherwise Lightroom won’t be able to find them.
    Windows—C: \ Users \ [your username] \ AppData \ Roaming \ Adobe \ CameraRaw \ CameraProfiles \
    Mac—Macintosh HD / Users / [your username] / Library / Application Support / Adobe / CameraRaw / CameraProfiles /
    For the lens profiles, substitute the LensProfiles folder for the CameraProfiles folder.
    The camera and lens profile file extensions are:
    .dcpr—camera profile recipe file used for creating/editing a profile in the DNG Profile Editor
    .dcp—camera profile
    .lcp—lens profile

  • REM profile and reduction period

    Dear SAP consultant,
    In REM profile setting, what the meaning of Reduction period (days) ? If i set to 30 days, can i backflush plan order earlier than 30 days ahead ?
    Rejoice

    Dear,
    Reduction period at OSP2 we define time for planned orders to be reduced.
    If you  enter the number of daysas 30 then system is to take into account when reducing the production quantities after 30 days. The period of reduction is calculated by adding the number of days you enter here to the backflush date.
    The 30 days will be taken as working days from the factory calendar and these days will be added to the backflushing date (means 30 working days in future).
    Hope clear to you.

  • How to use ICC profiles and soft proofing profiles?

    Hi,
    I got an Epson Stylus Pro 3880 and Epson Hot Press paper which, upon investigation, received great profeesional reviews and, having never printed digitally before, I don't know how to use profiles for soft proofing or printing.
    I don't know where to go in Aperture or what to do. My driver is up to date and I downloaded the paper profile - not sure where it ended up. What's next?
    So far as I know, soft proofing is about calibrating the monitor to the paper - am I correct?
    Thanks guys,
    Raphael

    Raphael,
    A good reply is going to require a full-size keyboard, which I don't have access to just now.  Here are some starter pages:
    http://www.cambridgeincolour.com/tutorials/soft-proofing.htm
    http://www.luminous-landscape.com/tutorials/soft-proofing.shtml (a bit grumpy and out-dated)
    Fwiw, I print to Epson Hot Press using a 3880.  Imho, it's a _great_ printer, and that combination of printer and paper produced state-of-the-art results.  (Not suitable in all cases, but if that is a look you like, the only thing that I've seen that surpasses it is the Epson 9900, and without looking at prints side by side you can not tell them apart.)
    Your profile ended up wherever you have told your browser to save downloaded files.  The Epson site should provide instructions on where to move the file.  Once it is in the right Finder folder, when you next Aperture it should show in your list of profiles.
    Keep in mind, though, that soft-proofing is useless without a well (read: hardware-calibrated) calibrated display.
    HTH,

  • Display profiles and soft proofing Windows RGB / Monitor RGB

    This might have asked before, but I did not find any definite answer for this. Sorry this gets a bit long.
    Short question:
    What's the difference between softproofing with Windows RGB and Monitor RGB targets? I see differences in my image between these targets.
    Long question(s):
    Here's some reasoning.. let me know when I go wrong.
    I have hardware calibrated my display Spyder 3 elite to sRGB standard. I have understood that the generated display profile contains a LUT table that affects gamma values for each RGB component, so that affects both gamma and color temperature. That table is loaded into video card when Windows starts. In addition to the LUT table, the display profile contains what? Probably information on what color space the display has been calibrated to. Does that matches directly with the LUT table information, but may deviate from sRGB in the case my monitor cannot reproduce sRGB 100%?
    Now if I have image that that is in sRGB, but the embedded sRGB profile has been stripped away, should any non color management aware image viewer show the colors properly, if it is assumed that 1) my monitor can handle full sRGB space and 2) my monitor was succesfully calibrated to sRGB and the LUT table has been loaded into video card?
    Or does it still require a color management aware program to show the image, which implies that the LUT table information alone is not enough and the display profile contains some extra information that is needed to show the image correctly? I would think this is true, as I needed to turn on color management in Canon Zoom Browser to see images in it the same way as in Photoshop.
    Now to the original question, what's the difference in Photoshop when soft proofing with Windows RGB and Monitor RGB targets
    I read from www.gballard.net that
    Photoshop can effectively "SoftProof" our web browser color:
    Photoshop: View> Proof SetUp> Windows RGB
    Photoshop's Soft Proof screen preview here simulates how unmanaged applications, web browsers, will display the file on 2.2 gamma monitors, based on the sRGB profile. If the file is based on sRGB and our monitor gamma is 2.2 and D/65 6500 degrees Kelvin, we should see very little shift here, which is the goal.
    Photoshop: View> Proof SetUp> Monitor RGB
    THIS IS WHERE the color-brightness-saturation problem will repeat consistantly.
    Soft Proofing Monitor RGB here strips-ignores the embedded ICC profile and Assigns-Assumes-Applies the Monitor profile or color space.
    The color and density changes seen here show the difference between the monitor profile and the source profile sRGB.
    I'm not sure how to read that. Assume here that my monitor has been calibrated to sRGB and the PS working space sRGB. Do in both cases photoshop strip away color profile from the image at first? What happens after that? Does in Windows RGB case Photoshop pass the color values as they are to display? What does it do in "Monitor RGB" case then? Does it assign my monitor profile to the image? If it does, does there also happen conversion from one color space to another? In either one conversion there must happen as the soft proofing results are different. Does either one cause "double profiling" to the image as the monitor is already calibrated?
    Thanks

    Windows defaults to sRGB if you don't calibrate your monitor so untagged sRGB files should display (more or less) correctly in applications that don't know about color management on systems with uncalibrated monitors.
    When proofing against Windows RGB you're proofing against sRGB, it will show you how applications that don't know about color management on an uncalibrated monitor will show the image. This is what you proof against if you want to see how the image will display in web browsers.
    When you proof against Monitor RGB, Photoshop will assign your monitor's icc profile to the image which tends to be utterly useless most of the time.

  • PNG colour profiles - and this format for print

    I know it's taboo to talk about PNG for printing.
    But I can't find and I've searched the forums - there was a post made about embedding colour profiles a while ago.
    I know PNG is a RGB only format, but I'm 36.8% sure I read something about embedding either RGB or ... wait for it CMYK profiles into PNG files.
    If anyone can shed any light on this - and how about PNG for print - I've been against it for a long time - but it is a lossless format, it can carry 64 bit data.
    I know I know - but I thought I'd ask anyway - see what people think.

    You can't save a PNG with a profile out of Photoshop, but it looks like you can embed one via the image events scripts that ship with OSX (/Library/Scripts/ColorSync/embed). Unfortunately ID ignores the embedded profile and uses the document's assigned profile instead. PNGs do respond to ID's RGB profile and the RGB profile will have an effect on the CMYK separation when it happens.
    Here's ProPhoto and sRGB:
    From your ID document you can also assign a profile, which conflicts with the doc's profile, by selecting the png and choosing Image Color Settings.... So, you could assign AdobeRGB as your doc's profile and assign sRGB to all your pngs.

    If you have CS4, you should update to ACR 5.2. If you install 4.6, you will break your CS4 install. Either just run the Adobe updater app, or go to http://www.adobe.com/support/downloads/new.jsp to download it. DNG converter is a separate download. Both camera RAW and NDG converter contain the final release version of the new profiles. DNG profile editor can still be downloaded from Adobe Labs: http://labs.adobe.com/wiki/index.php/DNG_Profiles.

  • Sort Profile and field LAGP-SORLP

    Dear fellow warehousers,
    In our storage bins we use the field REIHF for sorting our picks. After assigning it to a profile and assigning this profile to our movement this works very well.

    Populating the field I can do in various ways, manual, CATT, using the Cross-line placement config, but I want to be able to sort it in a different direction.
    Does anyone have experience with this challenge?

  • Denying removal of Trust Profile and RemoteManagement Profile

    We are a healthcare environment that is slowly rolling out iPads for certain areas to use internally. I have been working on setting up the Profile Manager via a Mac Mini with Lion OS. I can lock down the profiles that are pushed to the devices, via Profile settings on the devices, but I have not found a way to prevent the removal of the Trust Profile, or the Remote Management profile.
    My concern is that some of our...'savvy' physicians may stumble around in the General settings, see the Profiles section, and go manually uninstall either/both of the Trust Profile or Remote Management Profile. The other Profiles, they can not remove.
    Is the inability to lock those 2 profiles down, purposeful?

    You certainly can (and should) password protect your settings profile(s) with a unique removal passcode. Your students would not be able to remove the settings profile since they wouldn't know the removal passcode that you defined.  The issue being discussed in this thread involves the Trust Profile and Remote Management profiles which currently do not have the same level of protection as the settings profile. Removing the Remote Management profile renders the device or Lion computer unmanageable by Profile Manager. However, the settings profile(s) would remain safe from end-user removal if you protected them with a removal passcode. I'm not sure what you lose if your users remove the Trust Profile. My understanding is that it's only used during the enrollment process.
