[BC4J] how to revert the value in an entity based table after exception

Hi,
I'm running BC4J 9.0.4.3.
I have a JTable with an AttributeListBinding to an entity based ViewObject.
I added an Validation to a setter method of an entity which throws a RuntimeException.
THe Framework correctly displays the errormessage, but the Table keeps the new entered invalid value.
What I want is that the value displayed in the table is revertet to tha last entry.
How can I do that?
bye

Hi Peter
Thank you for your suggestions, both of them are interesting but unfortunately they do not solve my problem, or at least I don’t know how.
I will try to better explain my problem
I have te table DBTABLE and another related table called DBDATES with colums(C1,DT1,DT2,TARGET) where I record periods of time and desired target. For instance my DBDATES table could have the following records
ONE; 01/01/2012; 31/01/2012; 100
ONE; 01/02/2012; 29/02/2012; 90
ONE; 01/03/2012; 31/03/2012; 95
TWO; 01/01/2012; 31/01/2012; 140
Exist a FK between both tables in the C1 column.
I have created an EO for the table DBTABLE with the tree persistent attributes (C1, N1, D1) an transient attribute (T1). The (C1,D1) is my DB primary key.
When I create a new record in the DBTABLE and based in the actual date I need to query the DBDATES table to check which is my TARGET and the valid target dates. For Instance if a record for person ONE is created on February 12, my TARGET is 90 from 01/02/2012 to 29/02/2012.
At the same moment I need to check the total amount of items record to the person ONE during the full target period.
Select sum(N1)
From DBTABLE
Where D1 between V2 and V3
And C1= V1;
Bind variables:
V1 = ‘ONE’;
V2 = ‘01/10/2012’ – queried from DBDATES
V3 = ‘03/10/201’ – queried from DBDATES
In resume, for a determined person when I create a new record in the DBTABLE I need to know their target for the actual period and how much as been record until now.
I don't know if is possible to solve this without using the View Objects, because I need to query the DBTABLE for a time frame and with bind variables.
Thank you in advance for your help.

How to change the values in an LOV based on values selected in another LOV

Hi,
I have a requirement in ADF where there are two LOVs. Based on the values that I select in the 1st LOV, the values in the second LOV should change dynamically.
Also, the 1st LOV accepts 3 values, for every value I select, a different query is executed to populate the 2nd LOV.
I have a rough thought that I can use 3 different read only view objects containing these 3 queries. And based on the value I select in the 1st LOV I can execute the corresponding View object from the backing bean. But my doubt is how to link the results of that query that is executed to populate the 2nd LOV.
Thanks in advance.

Hi Brisk,
Thanks for your reply.
The link that you have provided explains how to disable and enable the other LOVs based on a parent LOV. But in my case there are two Select One Choice fields i.e. the dropdowns (sorry that I addressed it as LOV in my previous post which might be confusing). There are 3 static values in the parent dropdown where each of them are associated with a different query. for e.g if the three values in the drop down are A, B and C; if i select A, then query associated to A should be executed ; if i select B, then query associated to B should be executed and if I select C, query associated to C should be executed. Then the output attribute of that query should be populated in the child dropdown.
Please let me know about the solutions to this.
Thanks,

How to revert the changes in SAP BI based on a particular user and date

Hi
I am new to SAP BI. I have installed the info objects from business content by choosing the option select necessary objects while installing the DSO 0PM_DS04. But later i came to know that some of the infoobjects are customized. But after the installation, the customized infoobjects have been overwritten by the latest content from RSA1 and all the customizations have been lost. Is it possible to revert back the changes based on a particular user and from a particular date.
Please provide the solution as soon as it is possible. Points will be definitely given. Thanks in advance.

Hello,
Just for your information thats why the customized objects are givena diffferent name then the BC objects.
I am not sure why you have customized a BC objects but you should always create a a Z objects if you want a customization.

How to Get the Unique Key results from OWB Tables after Profile

Hi,
We are using OWB 10gR2(Paris) Beta Version.
In this version the new feature is introduced is Data Profiling.
We are using this feature to analylize the data in terms of stanadards.
We have done profiling for our tables and we are able to see the results for each table in OWB Profile Results Canvas. In this window one Unique Key tab is there to see the Unique results.
Now my question is where these results will be stored in standard tables of OWB. I want to know those exact standard tables to extract thoes Unique results in to my reports.
After profiling we are generating HTML-DB reports to view all these profile results. But we are not able to find the Uique Key tables where these results are stored.
So pls can anybody provide help on this to get these tables...
Thanks in advance...,

You can use DatabaseMetaData#getPrimaryKeys.

How to get the values from popup window to mainwindow

   now i am able to display popup window with values.How to get the values from popup window now.
   I can anybody explain me clearly.
Thanks&Regards
kranthi

Hi Kranthi,
Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.

How to get the value from databank

Hi,
How to get the value from databank? and how to set the same value to visual script object?
thanks,
ra

Hi,
You can use GetDatabankValue(HeaderName, Value) to get the value from databank and SetDataBankValue(HeaderName, Value) to set the value to databank.
You can refer to the API Reference to see list of associated functions and techniques we can use with related to Data Bank.
This is the for OFT but if you are using Open Script then you have direct access for getting the databank value but when it comes to setting a value you have to use File operation and write you own methods to do the set operation.
Thanks

How to get the values from table region and how to set

Hi,

Thanks in Advance,
Hanimi

Hi Hanimi,
1. You need to extend the VO, add a new Attribute.
2. In VORowImpl of the extended VO, you can find the getter for your new attribute (example getItem())
3. In this getter method you can write some code like:
if("ABC".equals(getItemDescription())
return "XYZ" ;
