  • Program To Identify the BP that are not assigned to transactions.

    Hai guys,
    I want to identify ALl the BPs that are not assigned to any of the Transactions like Oppurtunities,Activities etc in our system,
    I can run report bu using the tables But000 and CRM_ORDERADM_H.
    Is there any easy way i.e a standard program in the system that does the work.

    Follow these steps to get the list of BP's assigned to transactions
    1. Copy the order GUID's from CRMD_ORDERADM_H
    2. go to table CRMD_LINK paste the copied order guid in place of GUID_HI and copy the GUID_SET.
    3.go to CRMD_PARTNER and paste the above copied CRMD_LINK GUID_SET in place of CRMD_PARTNER GUID and copy the PARTNER_NO
    4.Go to BUT000 paste the above copied CRMD_PARTNER PARTNER_NO in place of GUID and get the partner number.
    Hope this helps out.
    Thanks,

  • How to select all the people that are not in any equipe  ?

    Hi,
    I have a nice SQL expression that gives me as a result all the "AGENTS" (people) that are working in an EQUIPE (a team)
    select a."AGENT_ID",
    a."NOM" || ' ' || a."PRENOM" "Nom",
    c.libelle "Equipe",
    a."DATE_EMBAUCHE" "Date embauche",
    a."DATE_DEBAUCHE" "Date débauche"
    from OBSERVATOIRE."AGENT" a,
    observatoire.equipe_agents b,
    observatoire.equipe c
    where a.agent_id = b.agent_id
    and b.equipe_id = c.equipe_id
    order by nom
    Now, how to select all the agents that are NOT working in any "EQUIPE" (team) ?
    I have tried but could not succeed !
    Thank you for your kind help.

    It is not working because the table EQUIPE_AGENTS does not contains a row if the agent is not into any equipe.
    CREATE TABLE "OBSERVATOIRE"."EQUIPE_AGENTS"
    (     "EQUIPE_AGENTS_ID" NUMBER NOT NULL ENABLE,
         "EQUIPE_ID" NUMBER NOT NULL ENABLE,
         "AGENT_ID" NUMBER NOT NULL ENABLE)
    CREATE TABLE "OBSERVATOIRE"."AGENT"
    (     "AGENT_ID" NUMBER NOT NULL ENABLE,
         "GRADES_ID" NUMBER NOT NULL ENABLE,
         "NOM" VARCHAR2(50 BYTE) NOT NULL ENABLE,
         "PRENOM" VARCHAR2(50 BYTE),
         "DATE_EMBAUCHE" DATE NOT NULL ENABLE,
         "DATE_DEBAUCHE" DATE)
    The only way to "know" if an agent is not into any equipe (team) is to search into the EQUIPE_AGENTS table, and if we do not find the ID of the agent into this table, then we know that this agent is not into any EQUIPE (team).
    I don't know ho to translate this into SQL.And that's what my query does. It uses an OUTER JOIN so that a result record is returned whether or not there is a record in EQUIPE_AGENTS. And the check for EQUIPE_ID is NULL restricts the result set to those where there IS NOT a record in EQUIPE_AGENTS.
    A more traditional way would be to use NOT IN or NOT EXISTS clauses, but they can prove inefficient.

  • What is the command to verify the configuration that are not saved or sent to local controllers?

    Q: What is the command to verify the configuration that are not saved or sent to local controllers?
    A: We can execute the command that is shown in below image to check the status of the configuration that has been made.
    Note: For example I made changes to the default VAP profile and executed the command "show master-configpending" which shows the pending configuration to be saved/sent to local controllers.

    But that jar file loads without images and icons when it is in other directory.Images should be accessed via a URL rather than using a filename because they will exist as entries in the jar archive not as files. Typically this URL would be obtained by using the Class method [getResource()|http://java.sun.com/javase/6/docs/api/java/lang/Class.html#getResource(java.lang.String)]. There are details in this [Java World article|http://www.javaworld.com/javaworld/javaqa/2002-11/02-qa-1122-resources.html].

  • Deleting photos in the Library that are not in an Album

    As the subject states, is there a way to delete all and any photos from the library that are not in an album. I now understand how to properly delete photos, but before I would drag the photos from a new roll into an album and then delete the ones I did not want from the album and they would stay in the library. It is too difficult and numerous to go back and try and figure out which photos are in albums and which are not. Thank you for your help in advance.

    Welcome to the Apple Discussions.
    Well, to find them, make a smart album (File -> New Smart Album)
    Album -> Is Not -> Any
    That will gather them together. The select them and go option (or alt) - delete.
    This will move them to the iPhoto trash.
    Empty the trash.
    Regards

  • HT4859 My phone was stolen.  I synced with my computer and lost some pictures that are backed up on the cloud.  How do I get pics from the cloud that are not in my photostream?

    My phone was stolen.  I first backe up from the icloud but then synced with my computer and lost some pictures that are backed up on the cloud.  How do I get pics from my old phone which are backed up on the cloud but are not in my photostream?

    If you have an iCloud backup, restore it to your phone as explained here: https://support.apple.com/kb/ph12521.  If you have a backup on your computer instead, restore it to your phone by connecting your phone to your computer, opening iTunes and going to File>Devices>Restore from Backup.

  • When I try to sync a new audiobook from Audible on my iPod, I get the message that's not possible because the iPod "may only contain content from two Audible accounts." I

    When I try to put an audiobook on my iPod, I get message the "iPod may only contain content fro two Audible accounts." I had an old Audible account, which I used to download books. I cancelled that and recently opened a new Audible account and downloaded the book that will not transfer to the iPod. I also have an iTouch which I bought second-hand, and the previous owner may have had an Audible account.

  • How do I delete places in the organizer that are not being used?

    In Elements Organizer 12, I think I accidentally created a "place" on the map that I do not want to apply to any photos.  When I try to do conduct an advanced search, the place is appearing as a checkbox.  I do not want this place to show up in the search field, as we have never been there.  How do I remove places that are not associated with any photos?

    If you are accessing emails from multiple devices, you are better off using the IMAP protocol. Then the devices sync with the server and they are all looking at the same information. With POP, you are going to get your emails spread about, some on Outlook, some on the iPad. It could get very confusing.
    By default, the iPad will not delete from a POP server. Instructions for changing this are here: http://support.apple.com/kb/HT3228

  • HT201077 How do I view photos saved to "the cloud" that are not in my latest thousand??

    How do I view photos held "on the cloud" that have dropped off the phone, ie, are not in the latest 1000 stored.
    I cannot seem to find this "cloud"!

    hi guys thank you for the replies, sorry I have been away.
    I am confused then - I have had to buy more icloud memory recently (2 of us use it with phones etc and so share pics, music) but I thought this was because its saving more photos?
    So no idea why I have to buy storage if you now say photos arent saved?
    If gone from the last 1000 they are lost? I dont have a Mac just iphone/ipad.
    Sorry if Im getting it wrong!
