Writing two linked objects (obj1 is linked to obj2)?

writing two linked objects (obj1 is linked to obj2)
Approach A:
ObjectOutputStream o = new ...
o.writeObject(obj1);
o.writeObject(obj2);
o.close();
Approach B:
ObjectOutputStream o = new ...
o.writeObject(obj1);
o.close();
o = new ...
o.writeObject(obj2); // append
o.close();
Does the Two approaches are same??
If not how many writes for Approach A and How many for B??
please explain me clearly for the reason ??
thanks

Hi All,
we facing an issue with sales order cost objective vs OKB9 cost object.
For IC PO service material, we assigned account assignment category 4.Reasonis Service material was not showing on G\R account.
The G\L account 7898788, we assigned to Service Item (material type DIEN) , for G\Cost 7898788 cost element is assigned in OKB9. Combination business + order 3478787.
Now conflict with sales order cost objective vs OKB9 internal order cost object.

Linking two ODS objects using a multiprovider

Hello Gurus,
I need to link two ODS objects and both are having 3 common characteristics and the relationship between the two objects are one to many.
My questions would be....
1)When the relationship is one to many can I set it up in the multiprovider to sum it up and show in the report?
2)I have 5 other charaterstics that I need to report(Slice and dice) on, but these are not common ones to both ODS objects. Is it possible for the user to get the report based on these charaterstics also? Or do I need to make sure that these 5 also exist in both DOS objects?
Thank you,
DM

Hi Sh,
Thank you very much for your reply. But I have few concerns.
1)One to many relationship will not have any effect on the data linking since the multiprovider clubs the key figures on common characteristics. I tried this on the system and it worked.
2)The problem would be not having similar characteristics on both infoproviders. So if I want to report on the chars individually it will have a problem( Will come as non assigned values)
But the documentation says the multiprovider supports Homogenous and Heterogeneous cases. Please refer the following link.
http://help.sap.com/saphelp_nw04/helpdata/en/52/1ddc37a3f57a07e10000009b38f889/frameset.htm
I am not sure what I can do now....whether to get all the characteristics in both infoproviders by enhancing the them. Or is there another way?
And lastly the scenario I am looking at is billing and cost of goods. So I might find records in cost of goods which may not have corresponding records in billing.(There can be goods in stock which need to be billed)The problem would be the way multiprovider link records(union) so it will have all the records from both sides even if they do not correspond to each other.
Let me know what you think.
Cheers,

Create view link between two view objects (from programmatic data source)

Hi Experts,
Can we create a link between two view objects (they are created from programmatic datasource ; not from either entity or sql query). If yes how to create the link; ( i mean the like attributes?)
I would also like to drag and drop that in my page so that i can see as top master form and the below child table. Assume in my program i will be only have one master object and many child objects.
Any hits or idea pls.
-t

Easiest way to do this is to add additional transient attributes to your master view object, and then include those additional transient attributes in the list of source attributes for your view link. This way, you can get BC4J to automatically refer to their values with no additional code on your part.

Can we link two business objects in workflow?

Dear All,
Can we link two business objects in workflow?My problem is that I have to take a standard BO for triggering my z workflow .But later in one step I am using BO which is Z as I am calling a standard Sap transaction in one of the method inside Zobject.
Please let me know how to go for it .
Kind Regards,
Anshu Kumar

Hi Anshu,
You can use the standard BO as the BO for your workflow and trigeger the workflow from its event. To pass values from the standard BO to the custom BO used in the activity step, you need to do proper binding between the std and custom BO in the activity step.
Do proper binding between event -> workflow -> task container.
For assistance on binding in workflows refer to the followng links:

View link creation on two view objects, and both view objects are populated program(not from sql)

I have master and detail VO , both views data is loaded in program. Now for show/hide feature, I create View Link Object and using one element from both child and master VO , View Link Object created properly.
But I can not able to add that view link object into AM.
Now because of that , I cannot say what is a instance name of that view link object.
Hence getting following error -- Invalid or missing view link. Please attach view link with the bean.
Please can you provide some directions.

How to automatically update Smart LINKED Object

Hi.
This is my first post here, I'm French, so excuse any English mistake i may do.
I'm not an artist / designer / ..., still new about using image software editing like photoshop.
So i downloaded Photoshop CC to try it because i wanted to do something on my spare time.
I want to render digitaly a card collection based on a online Collectible Card Game (Duel of champions if you wanna know).
For this I downloaded their card art from their site.
Then i want to add several effect / filter to render them nicely.
So i read and watch many tutorial in this purpose.
I ended with a good result for 1 card.
Here is an example :

I want to render digitaly a card collection based on a online Collectible Card Game (Duel of champions if you wanna know).
For this I downloaded their card art from their site.
Then i want to add several effect / filter to render them nicely.
So i read and watch many tutorial in this purpose.
I ended with a good result for 1 card.
Here is an example :
So what i did :
I get a source card art image, adding its red border, embossed it to get relief, adding a gloss effect in 3 different layers (the card art, the border and the gloss effect). Than i duplicate all this layers, swap them vertically and moved down to get a reflection.
I added a gradient to this new group of layers to have a nice fading effect to the reflection.
As I do not want to redo all the process again and again if I change main the source card Art, I want the reflexion to automatically update.
This was done using Smart object, both main source card Art and the (vertically swapped) reflexion card art using the same object storing my different main source card art.
So when i change in this object the main source card art used, it automatically change both the rendered card and its corresponding reflexion.
And then i Added a displacement filter to simulate a water reflection.
And the first problem (solved by now) occurred :
If i want to apply a filter to the group of layers corresponding to the rendered reflexion card, Photoshop have to convert and merged the whole group of layers into another new smart object and then apply a smart filter onto it. That worked but i lost the auto updating of the reflexion as the previous conversion have made Photoshop create in fact a whole new duplicated object storing a my different main source art.
So i partially resolved This by using Smart LINKED object instead of Smart object. I say partially because it is not really fully automated anymore.
Now if I change the main Source card Art to render a new one, I have to "manually" save file / update smart object to get the reflection updated.
I kinda accelerate this using a action performing a batch of saves to get a "save all" options (that clearly miss in photoshop). But for this i still have to open all my smarted linked object in order to apply the "Save All" batch.
But know I want to generalize the process to cards left, and render my whole card collection.
So i created a template based on what i've done so far using in this template Smart LINKED Object for the Main source card art and the reflected one. By the Way I exported the Reflection group in a PSD file, and refered to it as another Smart LINKED Object in my template. Doing so i'm sure Photoshop no more use a temporary PSB object correspond to the converted / merged reflexion Smart Object (remember : created in order to apply a smart Filter on it).
So what Happen now ?
I create a new testing psd file in witch i embed several new smart objects each one is an occurence to my template. Here i have to used smart Object and NOT smart LINKED Object because if so i'll always end up with the same rendered card several times. I have to get Phososhop create it own temporary duplicated object so a modification to one don't affect all the others after "Save All" batch on the corresponding working card.
So with what I have now, if I want to change 1 of the rendered card, i go its corresponding (duplicated) template object and from there i access again my LINKED object storing all my main source card Art.
I change to what source card art I want, and I have to open the reflection smart LINKED Object too in order to apply the "SAve All" batch.
Here is the "fun" (issue) thing : I have to apply the batch 3 time in a row to have the rendered card changed in my main testing psd file. I suppose saving 3 time time propagated the change along the Smart LINKED Object chain.
AND I have to make sure ONLY the corresponding smart (LINKED) Object file are opened before. If another file from a different rendered card is opened too the change will also be propagated to it and so having a duplicated rendered card. (I only want each card rendered once, but using the same template to avoid repetitive work).
So I explained in detail, but maybe not clearly, my situation and the step i went through.
TLDR
To summarize : I have a collections of Card art (jpeg).
I created a Template applying effect to render 1 card.
I created another template appliying same effect to render 1 REFLECTED card.
In both i use the same Smart LINKED Object that Store my collection on Card Art.
I make another Smart LINKED Object in the first template that reference the second one.
So with my first template I can update the rendered card and its rendered reflexion after changing the main source card art in the subsequent smart LINKED Object that store my whole cards art. I have to had all corresponding Smart LINKED Object file OPENED and save them all to have th updated result.
So not really automatic.
Then I want to render my whole card collection with effect and reflexion.
I create in my project a duplicate of my first template for each card to be rendered.
Then I have to open ONLY all subsequent corresponding Smart LINKED(or not) Object file of current working rendered card and change the main source card art, save all the file (several time to propagate change) to properlly update the current rendered card.
I have to do this for EACH of my duplicated template in order to render EACH of my cards.
Definitively not automatic process, and prone to errors.
Do you know a way to fully automatically render my card collection ? The only thing I want to do is chose one time the main source card art for each rendered card.
Finally another way to explain this issue and maybe get an answer is to instead explain simply what I want to do :
I have a collection of (jpeg) card art from an online card game.
I want to render them all with effect (gloss, emboss border, faded and water filtered reflection).
I want to do this automatically.
The only thing i manually want to do is chose the card art to be rendered for each of the card i want to render in my collection.
Here is an image of what i want based on what i've, not automatically, done so far :
Thanks for any help from photophop professional here.

Hi,
The delta load does not work for product categories but only products.So to bring in the new product categories into SRM you will need to start the load of the object DNL_CUST_PROD1 again.
The CRM middleware allows the following two methods for replication.
-Initial loads:
Launched manually (R3AS), the objects (customizing or business) are replicated between SRM and R/3, according to the filters you've put on the object (R3AC1 for Business objects like MATERIAL, R3AC3 for customizing objects like DNL_CUST_PROD0 and 1).
-Delta loads:
This option is only possible for Business objects, which is the case of MATERIAL.
With this option a daemon is launched between the 2 servers. Every modification made on an object on SRM or R/3 is transfered as soon as this object is contained in the filter retrictions (creation and/or modification). this is done through transaction R3AC4.
Also refer the foll thread:
Material group from R/3 to COMM_CATEGORY (SRM)

Field "Location of Linked Object" missing after adding a page to a role

I am using EP5 (5.06.01.00). After adding a page to a role, the properties of the page in the role no longer include the field "Location of Linked Object". The properties now only consist of two fields: "Name" and "Location". They used to contain a third field "Location of Linked Object", in fact, in older roles the page properties still contain this field. However, when I now add pages to a role or workset, this third property field "Location of Linked Object" is not there. - I am adding the page by clicking the "Add" button to move a page from the "View" area to the role in the "Edit" area. - I have been observing this symptom for several months, but I can not identify any configuration changes or upgrades which would have caused this behavior.
All hints will be greatly appreciated.
Thank you

Transporting/Deploying Portal Content and Delta Linked Objects

I researching the best way to trasport/deploy changed ESS Portal content from sandbox to D>Q. I have become familiar with the few changes my co. needs to deploy part of ESS. I have read articles that say it is wrong to modify the "Content Provided by SAP". The recommendation appears to be "use delta link objects". I created the necessary delta links in a new directory.
How do I get the delta link objects to display instead of the sap source objects? I this primarily related to how the portal is configured or how the content is managed?
I'm really sorry about the general question (in advance) but this stuff is new for me and I'm essentially looking for some good direction here.
Thanks,
James

Hi James,
Yes exactly right. You should create your own PCD folder under Portal Content to store your objects. How you structure that is entirely up to you, however in my experience I have seen two ways
1. First by Function or Dept (e.g. Finance, Logistics, HR) then by technical object (iView, role etc...)
2. First by Technical Object (e.g. iViews, Roles, Worksets etc...) then by function or dept or region (Finance, HR etc...)
Number 1 makes more sense to me. Just some other tips when it comes to creating PCD content:
1. Put everything in your own namespace (e.g. com.mycompany) that way it is easy to separate from SAP content using filters.
2, Come up with a logical naming standard so you can easily identify content by group, function and technical type (e.g. for an iView you might name it whoswho with the prefix com.mycompany.hr.ivu resulting in a name com.mycompany.hr.ivu.whoswho)
2. Don't give PCD folders any prefix (e.g. com.mycompany) as it ends up elongating the resulting URLs unnecessarily and you can run into problems down the track.
Hope this helps you.

Smart Object as traditional link (as in InDesign or Illustrator)

Is there a way to link a smart object, so that updates are made to the originally placed object ....as opposed to creating a new vector file save in a temporaray folder. Is there a way to work with smart object like traditional links in InDesign and Illustrator?
Thanks

How do I (or can I) convert an embedded smart object into a linked smart object

If I start with an embedded Smart Object (S.O)., can I easily convert in into a linked type of S.O.? I have not seen this feature available in the tooling yet. Please advise.

Since an embedded smart object is, well, embedded, there's no way to just convert. You'll have to point a link somewhere.
If you want to keep the smart object as is, open it and "Save As" to a new location, then link to that (Place Linked). Then delete the old.

Convert an embedded smart object to a linked smart object

Hey guys,
love the new "linked smart object" functionality. However, I can not figure out how I can convert (or export) an existing embedded smart object to a linked smart object.
I have a huge photoshop file with several embedded smart objects that I would like to break down into a lightweigt photoshop with with links to the varios smart object photoshop files.
Is there any way to do this?
Thanks,
Philipp

Thanks a lot guys.
I am just now putting a document together with linked smart objects and I'm noticing that the file size of the PSD file still increases quite a bit. I thought the hole point of this was to have lightweigh psd files?
I currently have 11 1920x1080 linked smart object files in the PSD and the file size is already at 140MB. Any ideas why this is happening?

How to use object collection with linked objects

Hi,I'm using VS2005 Crystal reports in a c# client app (server has database, but client does not have!). So the use of the objects transfered to the client seemed to me a good solution for showing reports on the client. The objects mostly link to several other objects (properties of type <type> or properties of type [] <type>) and the links are correctly configured in database assistant.But: Whenever using one of the linked fields, all of the main fields will never show up in the report.So, what is the correct way of showing a master / detail report using linked object collections??? (A small test sample app can be provided upon request) TIABP

What database and connection type are you using? Are you connecting the report directly to the database, or trying to assign the datasource to object data?
It sounds like you might be trying to use a linked list, collection or other C# construct to pass your data in. This currently isn't supported by the Crystal Reports SDK. You can use a DataSet or a DataTable, and possibly also an IDataReader depending on which version of Crystal Reports you're referencing in your project. Of course you can also connect directly to the database, even if the database isn't on the same machine as the application.
The way to show master records with detail information is through the use of subreports and linked subreport parameters. Linked subreports take their parameter value from a record in the main report, so that only the data appropriate to that master record is displayed. The guys over in the [report design|SAP Crystal Reports; forum can help you out with this if you have questions on the specifics.
