Passing a default value to the master block and do the auto query

Hi
My problem is i have a MD FORM to which i have to pass a default value and do an auto query so that when i run the form the form should open with this default value and do the query and get the details.
I tried many things like trying to set the value of the column using p_session.set_value and then calling the same form using wwa_app_module_link by using the value in the condition but every time unless i press the query button i did not get the values.
Now i don't know what to do.
My portal version is 3.0.7.6.2
Some body please help me
thanks

I don't think this works for 3 parameters, but I know it will work for 1. Maybe you can do something with it.
1. Create a link to the destination component (YourProvider.YourLink)
2. Use the code below to use that link to pass the value of a form field to the destination component. 'FieldName' is the field on the destination component you want to query, and '_FieldName_cond' is the condition. This creates the destination URL.
3. wwa_app_module.set_target(l_url) will send you to the URL you generated.
l_url := PORTAL.wwv_user_utilities.get_url('YourProvider.YourLink', 'FieldName', v_YourParameterValue, '_FieldName_cond', '=');
portal.wwa_app_module.set_target(l_url);
I'm not the best at this, but this works for me in most cases.

  • HOWTO: Avoid go to detail block without fullfill the master block?

    Hi:
    I have a master detail form with 2 blocks. When the user open the form the focus is on the first text item (required = yes) of the master block. If the user tries to get out of that item with keyboard (tab or enter), it gets the correct message saying that the item is required and must be filled. But the problem starts when the user click with the mouse on another item of the detail block. Here, I will have 8 or 9 messages saying that is impossible to create records without a master record. This is really annoying. This message has no ID (FRM-XXXXX), and I really must get a way to forbide users to go to the detail block without filling required items in the master.
    Anyone?
    Best Regards
    Joao

    Hello,
    if there is a relation between the two blocks double click on that rel.and mark the check box property:prevent Masterless operation try this option and tell me what's ur feed back..?

    I didn't really have time to dig in and understand your program in depth,
    but I have a few tips for you that might things a bit easier:
    - You use local variables excessively which really complicates things. Try
    not to use them and it will make your life easier.
    - If you flowchart the design (very similar to a dataflow diagram, keep in
    mind!) you want to gather data, calculate a value from that data, store the
    calculation in an array, and loop while the time is in a certain range. So
    theres really not much need for a sequence as long as you get rid of the
    local variables (sequences also complicate things)
    - You loop again if timepassed+1 is still less than some constant. Rather
    than messing with locals it seems so much easier to use a shiftregister (if
    absolutely necessary) or in this case base it upon the number of iterations
    of the loop. In this case it looks like "time passed" is the same thing as
    the number of loop iterations, but I didn't check closely. There's an i
    terminal in your whileloop to read for the number of iterations.
    - After having simplified your design by eliminating unnecessary sequence
    and local variables, you should be able to draw out the labview diagram.
    Don't try to use the "insert into array" vis since theres no need. Each
    iteration of your loop calculates a number which goes into the next position
    of the array right? Pass your result outside the loop, and enable indexing
    on the terminal so Labview automatically generates the array for you. If
    your calculation is a function of previous data, then use a shift register
    to keep previous values around.
    I wish you luck. Post again if you have any questions. Without a more
    detailed understanding of your task at hand it's kind of hard to post actual
    code suggestions for you.

  • Can I adjust all the master gains for all the keyframes at once?

    I edited a whole scene and keyframed some corrections but I wanted to change a few settings for the keyframes such as master gain. Is there anyway to fix this so I can just adjust all the master gians for all the keyframes at once? Thanks!

    If its the vignette geometry that is keyframed, and not the corrections, as written, (there is a distinction) then the color values are presumably NOT keyframed, as the keyframe only applies to that room/component of the grade, and not the whole grade. Your Primary In correction, in this case, is NOT keyframed and all the normal rules for revising corrections apply.
    Apple COLOR has a systemic definition: a change in values for a ROOM is a "correction", and the accumulation of corrections for a clips is a 'grade'.
    Keyframes only govern the behaviour of the room that they are created in, and don't apply across the board to the whole grade. The advantage is that the corrections can act independently.. the disadvantage is that the grade itself cannot be copy-and-pasted into another keyframed clip without any preparations.
    There are ways of doing that that are not in the Manual.
    I concur with your view of tracking, and you do have to do a wetware estimate to decide whether the investment is worth it... maybe a start and end keyframe is all you need, and adjust the trajectory as required.
    Wetware= that 'goo' between most people's ears, that starts right behind their eyes.

    Filemaker Go is a app that the user will have to have

    Help Me please

    That would be software. And, you said "upload." That's "uploading software." Why do you question what you stated?
    I don't know where you even want to upload this software. The only way it can be downloaded to a device is through the iTunes store. Do you even know what you want to do?

    Srinivas

    Hi Srinivas,
    According to your description, my understanding is that you want to change the master page and theme dynamically based on the anonymous users or authenticated users.
    Per my knowledge, there is not an OOB way to change the master page and theme dynamically.
    SharePoint is based on Asp.net, as we know Asp.Net request processing is based on pipeline model, so we can delevlop a custom HttpModule to dynamic change the master page based on current logon user profile(using SP Object Model to get).
    Another solution could be to use the SecurityTrimmed control that injects the CSS depending on global user permissions, more information, please refer to
    it.
