Hi Marc,
Thanks for your support and great help for the problems we are facing in IP. Now we are able to get the browser screen for selecting the file, but we are facing new issue, When we are uploading file, the system is giving dump saying "THE ASSERT CONDITION was violated" in the below source code:
LOOP AT n_t_charsel INTO l_s_charsel WHERE sign = 'I' AND opt = 'EQ'. 
  ASSIGN COMPONENT l_s_charsel-iobjnm OF STRUCTURE <l_s_data> TO <f>. 
  ASSERT sy-subrc = 0.                                                                               
IF <f> IS INITIAL.                                                  
    <f> = l_s_charsel-low.                                            
  ENDIF.                                                              
ENDLOOP.                                                              
(We are unable to open the Blog, it is showing us "No Authorization" message)
Thanks,

  • *** Question How to load a file into BI-Integrated Planning and use WAD 7.0

    Hi, I created an manual DTP upload to my planning infocube and it works fine.  The transformation rules convert 0CALMONTH into the relevant Calendar and Fiscal characteristics.   So all of my Time Characteristics are fine, both Calendar and Fiscal.
    However, When using the "How to load a file into BI-Integrated Planning and use WAD 7.0" solution, only the Calendar Characteristics are populated and not the Fiscal.   The upload application somehow knows to populate the 0CALMONTH2, 0CALQUART1, 0CALQUARTER, and 0CALYEAR.  
    How can I get the upload to populate my Fiscal Period Characteristics?
    Would it be best to modify the "Upload Application, or can I write a planning function to update the fiscal characteristics, or some other way?
    Thanks!

    My planning data is being uploaded via the SDN Planning File Upload Solution. What I did was end up modifiying the upload class ZCL_RSPLF_FILE_UPLOAD Method EXECUTE.
    I added the following code if anyone is interested.

  • MISALIGNMENT PROBLEMS USING "LOAD FILES INTO PHOTOSHOP LAYERS" FROM BRIDGE CC

    I'm having a persistent problem which technical support was unable to resolve after being on the phone with them for 1.5 hrs. I was told the issue would be escalated... That was five days ago, and I've heard nothing.
    Here is the problem: In ACR working on a bracketed group of five images shot from a solid tripod in Bridge CC. I carefully synchronize all parameters incl. crop, transform, exposure, etc. Then I go to Tools / Photoshop / Load files into Photoshop layers, and the images open in photoshop in a layered file..., BUT some are knocked out of alignment. Actually they have been cropped slightly smaller than the original file, always by the same number of pixels. Sometimes all layers are affected, sometimes not.
    Photoshop CC & Bridge CC are both up to date, as is the camera raw plugin. I’m on a new iMac i7 4-core, OSX 10.9.4. All software was newly downloaded from Adobe two weeks ago. I have reset preferences, reset tools in Photoshop, even uninstalled and reinstalled Bridge CC 6.1.0.115 all to no avail. Any suggestions? I am desperate for some help.

    I run Windows 7 Ultimate, I have 2.00GB of RAM with 1.74 usable, and I selected 40 images, each about 2MB.

    Hi JJMack - I just re-read your post. For some reason I thought you were suggesting to make sure "Open documents in Tabs" was selected, it was. Now I realize you were suggesting to turn it off! As another attemp to solve this problem I did de-select it today. Seemed to work for a good while. I was getting very excited, then, on the last set of images I had to do it displayed the same problem. But, it did go for quite a while without failing, and when it did I was thrashing about trying to make another app active. When loading documents like this - with "Open documents in Tabs" de-selected, Photoshop wants to put the loading images as the front-most window, no matter what other apps (Bridge, email, web etc) I click on in the dock. I think it is related to the bug you described effecting the "load files to stack" command.
    Hopefully Adobe is looking at this - mind you, I have read reports of people having this problem in CS5! Looks like that was never resolved sadly.
    I'll keep testing and post back.
    I am looking to upgrade my video card to see if it's a video memory thing.
    What is very weird though is the fact that this problem didn't present itself until after several weeks of working with this command with no problem. No additional apps installed, nothing changed. Why would it start happening only after a while?
    Thanks again for your suggestion.

  • Load files into Stack Problems

    So what happen was this. I make GIFs as a hobby. But what happen was that 3 days ago, I opened my Photoshop CS5.1 Extended version 12.1 (x64) and did the usual thing.
    I went to Scripts and to Load Files into Stacks. I loaded my files and pressed OK. So here's the funny part, usually, the pictures will load by itself and eveyrthing will be in order. But what happen was that the layers load to around 6 to 7 layers and everything just disappear. Literally disappear. Like I didn't even load anything. No canvas, no images, nothing. I thought it was a bug or something so I reinstalled my CS5 but the problem remains.
    So I try with my CS6 Extended version 13.0 x64. (That I barely use because I'm still more comfortable with CS5.) And the same thing happens.
    I decided to Google it and nothing comes up. I do not know whether is it my laptop or something went wrong somewhere. This has never happen before for the amount of time I have CS5.
    I even change my scratch disc space. Last time it was on (C) with around 20GB space and nothing happens. So I changed it to my D drive and it has atleast 150GB space. I even tried closing every applications I have to test whether is it something related to my ram. But nothing happens. The problem remains.
    So I require some help because I asked around and it appears that none of my friends knows whats wrong.
    Here's my system information:
    Window 7 Ultimate Service Pack 1
    Intel (R) Pentium (R) CPU B970 @ 2.30GHZ
    6.00 GB Ram
    Running on 64-bit OS
    Graphics:
    Intel(R) HD Graphics Family

    When you start having problems with Photoshop.  Most of the time its because of something external to Photoshop or your user id Photoshop preferences.   Reinstalling Photoshop seldom fixes these problem. For User preferences survive across the reinstall. Third party plug-in may as well. Since you have the problem with both CS5 and CS6 it may have to do with the files your loading into the stack. For that something both version are trying to process.  CS5 and CS6 haves separate Preferences and third party add on must be installed into each though they may share plug-in if you use Photoshop Preferences to and a additional plug-in path and you use the same path for CS5 and CS6.

  • Loading file into BI

    Hi,
       I am trying to load file into BI using GUI. 
       When I tried an upload for cost centers to BI, but I got a message that it was locked by some other User.  Is there any functionality in BI that checks, if other users were in BI before it would perform the upload.
       If there is any such Locking concept in BI,  where can I get the documentation of the same.
    Thanks,
    Arshad

    Hi Arshad
    Try tcodes: RSPLSE for Lock Management.
    You could use process chains to check and delete locks and then perform the upload.
    Also check this blog of Marc's. It might give you some ideas.

  • "Load files into Photoshop layers" fails to complete CS6

    Hi all,
    Hoping someone can help with the folling problem with Photoshop & Bridge CS6
    When in Bridge, after selecting 6 images (CR2) using the command TOOLS>LOAD FILES INTO PHOTOSHOP LAYERS the first file will load into Photoshop, Photoshop will then generate a second blank layer and then read the second file. At this point the "script" will stop. I am left with a document with 2 layers. The top layer has my first image, the bottom layer is empty.
    At this point when I quit Photoshop I am prompted to save this open document which appears to be the only open document. I choose not to save this as a file. I then get a dialogue box prompting to save another open document. Photoshop has loaded the second file to place as a layer but as the "script" has aborted I am left with an open, but invisible file.
    When I first loaded CS6 on Snow Leopard, it would demonstrate this behaviour every time I attempted to run this command from Bridge.
    I did a clean install on a blank HDD of OSX Lion. Installed CS6. The command worked without fail for about a month.
    Then I would get the command aborting occasionally. Restarting Photoshop would let me continue for a few hours before this aborted script problem would happen again.
    Over the last week it has become more frequent, to a point where this workflow is unusable.
    A restart of Photoshop may fix the problem for the next batch of images, only to fail again soon after, or fail on the first attempt after a relaunch of Photoshop.
    A reboot of my computer will allow my to load one or two sets of files before again failing to complete the command.
    I have tried the following:
    In Photoshop preferences:
    disabling the "Use graphics Processor"
    Increasing or decreasing the amount of RAM available to Photoshop
    Changing the cache levels or changing the cache tile size
    changing the scratch disk
    Trashing the Photoshop preferences file (Photoshop Settings.psp)
    In Bridge
    Purging the cache
    Increasing or decreasing the cache size
    Resetting Bridge preferences (holding Command on launch) and deleting all cache files.
    In general system
    Quitting extra programs (Safari, Thunderbird, iTunes)
    Sometimes this will seem to then allow Photoshop to load a full set of images, only to abort again after a few sets.
    Rebooting the computer - again will work for a few images sets before again failing.
    Now the fact that it worked fine for several weeks without presenting a problem would indicate that it is not a bug.
    The fact that is slowly started happening then became more frequent would indicate something changing slowly over time - a larger cache folder perhaps, although purging known Bridge cache folders has not filed the problem.
    Really at the end of my tether here. Even considering downgrading to CS5 - but don't want to have to use the older Adobe Camera Raw.
    System is as follows:
    Mac Pro 2 x 2.66 Quad Core
    24GB RAM
    ATI Radeon HD 4870 512
    OSX Lion 10.7.4
    I have seen a couple of others have posted having a the same problem, both with CS5 and CS6.
    Hoping someone has an answer.
    Thanks.

  • PS CS3 extended "load files into stack" question

    Hi,
    I've been trying to use the "Load files into stack" script in PS CS3 extended but the problem is that if for example I have files with these names:
    File_1
    File_2
    File_3
    when I use the script it puts them together but in the wrong order so in my layers they are like this:
    File_1
    File_2
    File_3
    which would be wrong because the File_1 is my first image but it's the last layer so if I make this into a gif file and watch it, it would play backwards.
    I was wondering if there is away to fix this. thanks in advance.
    PS: If there is anything I need to provide to make it easier for you to help me, please ask.

    Thank you jugenjury for your fast replay, but let me explain what exactly I'm doing maybe it helps, I'm not very familiar with PS so I'm kinda confused about what you just said.
    I'm trying to make a .gif from an .avi file. I tried using the File>Import>Video Frames to Layers but I get all blank layers so I used another program to take mass screen shots. so I have 133 images which I want to make into a .gif file. I use the Load files into stack script then in the animation tool I select the "make frames from Layers". It all works out so far but the problem is that the video plays backwards because of the problem I explained in first post.

  • " Load files into stack" Crach photoshop CC since the last update

  • Adobe Bridge CC 'Tools Load Files Into Photoshop Layers' missing from menu.

    Hi,
    After updated to bridge CC the 'Tools > Load Files Into Photoshop Layers' has simply disappeared from the menu! Is there a plug in that I'm missing or is this something similar to how the Output module works, where you have to install the files manually?
    Thank You

    I uninstalled all Adobe products -> reboot -> reinstall; which didn't work.
    So I had to uninstall all Adobe products again, then use the Adobe Creative Cloud Cleaner, reboot & reinstall everything again; then it finally worked.
    This seems to be a regular thing since the introduction of Adobe CC, almost every new update or new versions breaks functionality & requires a complete uninstall -> reinstall process.

  • Why while in Bridge Load Files into photoshop Layers does not work?

    In Bridge, Tools>Photoshop>Load Files into Photoshop Layers does not work.  I have two images selected and when I execute that comman in Bridge nothing happens.  I exited and restarted both PS and Bridge and still nothing.  I am working in Windows 7 and Photoshop cs6.

    No I tried File/scripts/load file into stack and still did not work.
    There was an update to bridge and now it works.  Thanks so much.

  • Load Files into Photoshop Layers hanging...

    I have both Bridge CS5 4.0.4.2 and Photoshop CS5 12.0.2 x64 open and running on a MacBookPro... when I highlight a few files inside of Bridge CS5, then go to Tools, Photoshop, Load Files Into Photoshop Layers, when those files start opening in Photoshop and stacking as Layers, the process just hangs and stops processing after the first Layer is placed - any ideas why this happens, or just a bug? Thank you!

    any ideas why this happens, or just a bug?
    As I can’t reproduce the issue so I would assume it’s not a bug per se.
    Have you tried trashing prefs for Photoshop (after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved and making a note of the Preferences you’ve changed)?

  • Can I modify 'Load Files into Stack.jsx' for custom white balance?

    I've been wondering whether its possible to change Adobe's 'Load Layers in Stack' script so that it loads RAW files with the white balance adjustments I have made in Camera Raw ('ACR').
    At present, the script loads the files as layers with the default ACR (or Lightroom) settings. This means that any white balance adjustments to the file in ACR are ignored and the RAW file is loaded with the WB 'As Shot'.
    It IS possible to save new ACR default settings, but this doesn't really help because I don't want the WB to be a constant value. The changes I make in ACR are usually subtle and 'by eye'.
    I would like the script to be mindful of these changes when opening the RAW file.. does anyone have any suggestions?

    This is part of the script looks interesting - is there a reference where can I find more hooks? Perhaps there is one that relates to WB?
    // LoadLayers is less restrictive than MergeToHDR
    loadLayers.mustBeSameSize                              = false;          // Images' height & width don't need to match
    loadLayers.mustBeUnmodifiedRaw                    = false;          // Exposure adjustements in Camera raw are allowed
    loadLayers.mustNotBe32Bit                              = false;          // 32 bit images
    loadLayers.createSmartObject                    = false;          // If true, option to create smart object is checked.
    // Add hooks to read the value of the "Create Smart Object" checkbox
    loadLayers.customDialogSetup = function( w )
