IF-conditions check order

Hi all,
I'd like to ask if it's safe to write such constructions:
if ((s == null) || (s.toString.equals(""))) {
I wonder whether it's guaranteed that firstly the condition (s == null) would be checked. If it is so, then we could be quiet of this code to be safe, otherwise - we could not.

if ((s == null) | (s.toString.equals(""))) {
  }it would check all the statements. But || && checks the other statements if it is needed. For example if the first statement is true then the || operand doesn't need to check the next statement and if the first statement is false then the && operand doesn't need to check the next statement.

    How do I "Launch" Adobe Reader in order to accept the Terms and Conditions in order to view PDF documents? ....Somers  I'm using a MAC with up to date software.

    Launching is just the normal word in Apple's word for "run an app". You can launch an app from the Applications folder, or in recent versions of Mac OS using the LaunchPad (rocket icon). You can't assume all your apps appear on the dock (bottom strip), it's only the ones Apple put there or you added.

    Is it possible to set the check order to be ordered by amount in payment batch?
    The only options available now are supplier name, supplier number, or postal code(Document Order) but I want to print by batch amount.
    Please advise.

    Hi
    There are options for first due date, last due date, terms etc, but matching with highest available invoice number is not an option as far as I know.
    Never tried but as an idea if I had this question...I could try this...
    1. Create receipts by automatic receipts creation....
    2. Run a custom program to re-arrange applications and amounts (use ar_receipt_api_pub for adjustments)
    3. Then Approve/Confirm etc.
    Emphasizing again, never tried such thing.

  • I want to create new popup block screen in CO11N SCREEN for condition check

    in standard CO11N screen after completing filling the required field , when i click the save icon I NEED TO CREATE THE POBUP BLOCK SCREEN FOR CONDITION CHECKING WHICH CONSIST
    YES    NO    CANCEL
    IS THERE ANY FUNC MODULES TO DO THIS? OR IS IT POSSIBLE BY CODING?

    Don't rely on 'Preview'.
    Share/Export as .ibooks file and then drag that to iTunes and sync to your iPad.
    Still no joy, find a pre-processing recipe ( that includes export for iPad) that doesn't spoil the quality in the process.
    Just keep in mind that low quality in means low or lower quality out, in this example.

  • Assigning Validation Rules to a Condition for Order Line entity

    Hi,
    Do we have any API(or interface) to load some validation rule( rule like 'Inventory Item= some item numbers) to a condition for Order line entity. (i.e. to load records into OE_DEF_CONDN_ELEMS).
    Please let me know, thanks in advance

    I am not sure of the purpose, if this to enforce a processing constraint, I will use API in the validation template defitniion and in the API I will qualify the items.
    You can have these items setup in value set of a look up (custom) and then have user interface control on the same.
    Is that what you are looking for?
    Thanks

    Are you seen that message when trying to view your orders from your Verizon account? I have the same issue but if you search your preorder confirmation number and enter you last name here Order Status | Verizon Wireless then it will at least give the vague details like, "your order has been received and is been processed" It will also show the expected delivery date.

  • Condition Checking

    Hi,
      Is there anyway i can ensure, let's say my "net income" is larger than 2 million before the user can submit the data? is there some sort of condition checking or locking mechanism that does this?
      any input on this?
    cheers

    You can have something like that for submission
    please check into help online the follow link
    http://name of your application server/osoft/help/admin/helpstart.htm#Setting_application_set_parameters.htm
    It is not exactly what you want but you can do something using this approach.
    You can change the work status settings for each application. Changing the work status settings involves identifying three to five 'work status dimensions,' and then defining specific members for the remaining non-work status dimensions used for validation purposes. You must determine which account you will use for validation of the data at the time the work status is changed. The validation account must be ”0u201D at the intersection of the 3-5 variable members and the members designated for the non-work status dimensions.  If the account is not ”0u201D then the owner/manager cannot set the work status.  This is an option feature.
    The dimensions you select as the work status dimensions are the variables in your business process. For example, the entity, category, and time might change based on who is submitting data, but the account, data source, reporting currency, etc., remains static. (Typically, Time is a work status dimension since data is usually segregated based on time.)
    For example, lets say that you set Entity, Category, and Timeas your work status dimensions for a given application. You then set your other current view members to the following:  Account: Validation; DataSrc: TotalAdj; Intco: All_Intco; and RptCurrency: LC. In addition to assigning work status dimensions, you also specify which dimension is the 'owner dimension.' The owner dimension includes the Owner property. The owner property determines who can edit a work status setting. The following figure shows this setup, where Entity is the Owner dimension.
    A user attempts to post data to the current view shown in the following table. The system checks the 'validation' account to make sure the intersection equals zero (0). If so, the data is posted, and a success message is displayed. The user can now set the work state to 'submitted' on that intersection. Subsequent submissions to that exact intersection will be rejected. Users can only send data to the same intersection if the Entity, Category, or Time member changes.

    To change work status settings for applications
    From the Admin Console, expand the Application node.
    Expand the application for which you want to change the work status setting.
    Select Work Status Settings.
    In the Work State column, select Yes for each dimension you want to use to control the work status settings. Select Owner for the dimension that contains the Owner property.
    In the Member Validation column, select a member for each non-work status dimensions. (Use the browse button to open the Member Lookup.)
    From the action pane, select Save Work Status Settings.

  • Manual price condition (%) in order creation (using ABAP)

    Dear community members,
    I could use some help on a problem I have encountered while creating a sales order (in the CRM system) using ABAP programming, the details are given hereunder:
    I have two manual price conditions used to set a possible discount, one using a straight value and one using a percentage:
    1. When the order is generated using the value (let us say 100€) it cointains the correct price condition.
    2. On the other hand, when the order is generated using percentages (i.e. 10%), it is created without explicit errors or warnings but with no price condition in it.
    For the latter case I have checked the IPC logs (from transaction SM53) finding this error message:
    Message: Condition cannot be processed manually

    I have already debugged FM CRM_ORDER_MAINTAIN but to no avail, maybe I just missed something and I can assure that the customizing is correct and aligned between the systems and both the conditions are set to be processed manually.
    At this point, since the condition is applied when the commit is yet to be done I wonder whether it is possible to apply a discount percentage on prices which are yet to be generated, it would be illogical to do so and then again while using a straight value (which does not require a calculation) the order is correctly generated.
    Furthermore when I add the conditions in an order (from both the GUI and the WUI) the table IT_PRIDOC is alway empty, even if CT_INPUT_FIELD is populated.
    I know that there are similar posts here in SCN but sadly I was not able to find a solution so any help would be greatly appreciated.
    Thanks in advance for any replies given,
    Alessandro.

    Dear Padma,
    apologies for my late reply. I also thought it should be possible to use a percentage but I was not sure.
    Sadly the debugging did not bring about any positive result.
    I also tried to make a second CRM_ORDER_MAINTAIN call after the system generated all the pricing conditions but that also did not work.
    There is one thing that caught my attention though:
    - YSCV (fixed amount): still no problem at all (passed to KBETR);
    - YSCP (percent): if I assign a value to KWERT or if I leave all the fields empty, the condition is created in the sales order but it is always set to 0%. However, if I try to assign it to KBETR, I always get the message: "Condition YSCP cannot be processed manually".
    I made some attempts with the customizing, for example adding the condition to the "easy entries" or playing with the options of "Create Condition Types" (always aligning the systems) without getting positive output.
    I am beginning to think that it could be an IPC-related problem (which is not my area of expertise... yet).
    Alessandro.

  • Copy price conditions from order to invoice

    Dear experts,
    I have a problem I can't solve myself !
    When we create an invoice from an order, the conditions are copied using a predefined pricing procedure in customizing ... Now, I think I have a strange problem ... When the conditions are copied from the order to the invoice, the inactive conditions are not copied (which seems normal) ... Now, I would like one inactive pricing condition (ZPRO) to copied always, because this one is mandatorry on invoice and otherwise I get an error while copying ... Is there a userexit where I can force this ? And how do I implement this ?
    Thanks in advance for the answers ...
    Greetz,
    Kurt.

    Hi,
    Try this.
    GO to the VTFA transaction..
    Give the source sales document type and target billing type..
    Press item button..Choose the item category..
    In the pricing type give "D" (Copy pricing elements unchanged)...And check again..
    This might work..
    Thanks,

  • Condition check in PO

    Hi guys,
    I've a problem: I have a condition type defined "Required" in calculation schema and the condition appear in PO with value zero. How can I do to check if the value is greater than zero ?
    Regards
    Alberto

    when you mark a condition as "Required"  , it only means that  the  condition type must mandatorily appear in the procedure ,  it however does  not check the value at all   ,   in order to check the value  ,  you  need do define Limits for conditions  , you  can define this under customizing for conditions in purchasing.  apart from this, you can also define some routine and assign to the condition type.
    If  the value for that condition is  based on some parameters ( e.g.  plant/ p.org etc)  , then you can define an access sequence and maintain condition records to default the same.
    regards

  • ABAP & Java conditional checks

    Hi folks,
    I'm running the IDM 7.1 Identity Centre, and when I assign a business role that has an ABAP and a Java privelege in it (And also when I unassign it...) the condition that checks whether the user has any priveleges in the system (and decides whether to delete him or not) seems to fail.
    That means my ABAP and Java users both are left in the repository with no roles/groups assigned.
    It seems to use the mxpt_check_account Stored procedure, which I've looked at, but cannot figure out why the condition is failing this check, and my users are not getting properly created/deleted.
    Any insight? Thanks im advance!
    Troy Shane

    Ok, I think you have it now, except for the exact order of things.
    Here's what I face right now:
    I assign a Business Role, with those 5 priveleges assigned to it, to my user, Larry.
    Larry gets created ok in ABAP and Java, and actually, the roles get assigned just fine there. If i change the role he's assigned to (Manager West, instead of East for example) I see them get updated with no problems (Very smoothly, in fact) in both the ABAP and the Java. For example, if I simulate a promotion for Larry through the IDM User Interface, and assign him a VP role, I see the roles updated properly. (Besides some SPML Date format warnings on the MX_VALIDFROM & MX_VALIDTO, but those I can live with for now.)
    However, I still, have two problems:
    1. It seems that NOW...(sorry, different behaviour now than when I first posted this message, due to the recommendations I've implemented) when I remove the Role assignment in IDM, the user's roles get removed properly in the repository systems. Then the tasks to delete the Java and ABAP users run, but they BOTH error out. It seems that the jobs that modify the role/profile assignments for both my ABAP and Java system (Standard SAP Prov Framework tasks - SetJavaRole&GroupForUser & SetJavaRole&GroupForUser ) also effectively deletes the users, because by the time the delete tasks run, the users are no longer there. These tasks throw the errors:
    Pass: DeleteJavaUser
    Error in delete: Can not delete object with id SPML.SAPUSER.Larry because Could not delete object as id seems to be invalid SPML.SAPUSER.Larry
    (...makes sense)
    Pass: DeleteABAPUser
    User Larry does not exist
    (...also makes sense)
    Ok, admittedly, this one is low impact, and I don't really need to get it fixed, I just want to understand why it is throwing an error...should it really be deleting the users when it first removes the roles, and then checks that there are no more privelege assignments for that system? (When I have 2 priveleges for the same system assigned through roles, it doesn't delete the user, just removes the role, as expected...no errors
    Ok, this one is my real issue now (Thanks for reading this far):
    2. I have the role configured as above, including priveleges from all 3 of my repositories (I hit "post" too early above):
    Role = ROLE:BUSINESS:SALES_EAST
    5 Priveleges total :
    - Z_INNOTECH_EAST-Group (JV1)
    - Eastern Region-Group (LABS)
    - Sales-Group (LABS)
    - Z_INNOTECH_SALES_EAST-Role (CR7)
    - Z_INNOTECH_SALES_EAST-Role (JV1)
    JV1 = AS Java 7.01 SP4 (EHP1 SP4)
    CR7  = SAP CRM ABAP 7.01 SP2
    LABS = Active Directory OU
    The ABAP & Java tasks faithfully fire now, every time I assign or unassign a Business role to my user Larry. (Yay!)
    There are also 2 AD groups (privelege) assigned to Larry through the role: Eastern Region group and Sales Group.
    There is also an inherited "Employee" Business Role, which has the AD "Employees" Group - for base employee access.
    The idea is that, a member of the Eastern Region Sales group would automatically be an Employee, so it is a Child Role of most of my major roles.
    When I assign this Business Role, the Active Directory tasks very rarely and very inconsistently fire...I am watching th results in the Job Log and also through my AD tools...
    I am using IDM 7.1 SP2 (Patched on Monday past)
    Using individual tasks through the IDM UI, I can create Users, and enable them...but the Provisioning seems not to work. I have the tasks set properly in the Repository definition and am using the SAP delivered ones (I have tried using modified copies with limited success, and am now back to basics) This proves it isn't the repository definition, or permissions on the repository. I'm always using the same Administrative user to assign/unassign these users, so now I'm stumped!
    Phew, ok that's enough for now...I'll post more error messages once I've investigated the AccountRepoName that you suggest...I haven't seen that Attribute and don't know if it is defined here.
    TIA (and so far...),
    Troy
    (Ok...how come I don't have any line returns in my message?)

  • Statistical Pricing Condition - Purchase Order

    Hello,
    We have a condition type in the Sales Order that is created as a Statistical Condition. However, in the PO this condition is being added in the net value. The item category for this item in the PO is 'Third-Party'.
    Is there a way to prevent this from happening.
    Thanks, Pankaj

    Hi Pankaj,
    The Pricing Procedures for Sales Order and the Purchase Order are different. So even if you have made a Condition Type as Statistical in the Pricing Procedure for Sales that doesn't mean it is going to be statistical in Purchase Calculation Schema.
    Check whether the Condition type has been made as Statistical in the Purchase' Calculation Schema.
    Regards,
    Karthik.
