Diff between BSP and WEBDYNPRO FOR ABAP?

Hi All,
can anyone let me know the Difference between BSP's and WEBDYNPRO FOR ABAP.
Regards,
Ravi

Hi Ravi,
In truth, Web Dynpro contains many of the enhancements than BSPs....like built-in value-help and select options...... they
will become standard in Web Dynpro. But these can also be added to BSPs also.
There are several architectural differences between BSP and WDA. WDA has some advanced features but more restrictive framework compared to BSP.
WDA is stateful only. While BSP supports both stateful and stateless programming models.
WDA doesn't aloow us to use our own custom HTML, JavaScript or other controls. To provide compatibility the rendering logic is completely hidden from the developer.
On the other hand, BSP has no such restrictions and allows an extreme level of custom rendering. This makes BSP a perfect platform for applications that require pixel-perfect layout or specialized UI elements.

What is the difference between list display and grid display in alv report

Hai genious
i am a new of the abap, i dont know the alv report, i have a small doubt, can u please tell me what is the main difference between list display and grid display in alv report
thanks&regards
chinnu

Hi ,
1. For all practical purposes, they are the same.
2. Some differences:
a) from abap coding point of view,
alv list is done with Function modules,
alv gris can also be done with FM,
but can also be done using OO concepts.
b) Alv grid (using oo concept) requires
designing the screen layout .
Hence, in one screen, we can show more
then one alv grid
(we cannot show more than
one alv list on one screen)
c) ALV grid uses ActiveX controls
present on the Presentation Server.
Hence, it consumes More Memory
on the presentation server.
d) ALV LIST is Display Only.
Whereas
ALV Grid Can Be made EDITABLE for entry purpose.
e) In alv grid, these options are possible,
but not in alv list.
without horizontal lines
without vertical lines
without cell merging during sorts
display total lines above the entries
I hope it helps.
Regards,
Mamta

Issue regarding cell action in webdynpro for abap alv

hello gurus,
       i have one requirement in webdynpro for abap alv.i have one alv table in that i have one coloun employee name.
for that i have provided F4 help and that is editable field.if i select value from F4 help it is getting value correctly and it is showing properly at the same time it is allowing values entered manually insted of from F4 help.but as per my requiremnet it should not allow any manually entered values.how can i get this functinality. i am not aware indepth od WDA.
could you go through my isssue and could you revert me some solution.
thanks in advance.

Hi,
   I dont think this is possible because when you can change the value using F4 then it would obviously be
   possible to enter manually.
   You can try using a drop down instead because in drop down you cannot enter values manually,
   But this would be good if the values that can be shown in drop down are very low, if the values are more
   then again user will face problems selecting values.
   Else you can try out what srinivas suggested, But dont know whether we can have two cell editors at a time
   inside a single cell of ALV. Please post the answer if you have found any other way to do it.

WDA: TreeByNestingTableColumn and ALV in webdynpro for ABAP

Hi,
1) I am trying to implement a tree with nested structure and multiple columns. I am using RecursionNode in the context and UI element TreeByNestingTableColumn. I am not able to figure out how to make a distinction between the key and parent key. In TreeByKeyTableColumn, we use key and parent key to differentiate. Is there any link which explains how to implement TreeByNestingTableColumn in Webdynpro for ABAP? (I got a link for webdynpro for java though).
2) Can ALV be used to implement a tree structure instead of using Table with TreeByNestingTableColumn or TreeByKeyTableColumn? Then I would be readily able to use ALV features like sort etc. If it can be used is there any link which explains how to do it in Webdynpro for ABAP?

Hi Srinivasa,
I can answer the first point. If you use a recursive node and TreeByNestingTableColumn, there is no need to have a rowKey and parentRowKey, since the recursion with the context already defines the hierarchy. As far as I know someone posted a blog that explains how to use the TreeByNestingTableColumn in Web Dynpro Java. I don't have the link available, but this blog would be good place to start. The implementation in WDA and WDJ is pretty much the same here.
Kind regards,
Thomas

In webdynpro for ABAP alv table issue

hello gurus,
                  i am new for webdynpro for ABAP.i strucked at one point at designing time.anybody could you suggest me on this.
thanks in advance.
let me explain my scenario first.
in my webdynpro for ABAP developement i have one alv table having ten fields.i am featching the data for eight fields from one Ztabale and updating , for rest of two fields we need to fill after displaying output using the respective F4 help. Right now these two fields are in input editable mode.now i am getting the values successfully from F4 help and at the same time it is allowing MANUAL ENTRIES also but as per my requirement it should not allow any manual entries . for this i have made these two fields are in readonly mode as like as rest of fields to avoid the MANUAL ENTRIES but at this time i didnot get any F4 helpfor those two fields.
so how can i achive my goal in this thing could any one suggest me.
my final conclusion is we need to get only F4 help values into those two fields . it should not allow any manual values at any point of time.
best regards,
babu

Differences between reports LL01 and LS24 for negative stock

Dear friends,
Could you tell me the difference between the reports " Warehouse Activity Monitor" (LL01) and "Stock Per Material" (LS24)..
When the negative stock option is chosen ,LL01 is not displaying certain materials with the negative stock.However these materials with the negative stock are displayed in the report LS24.
What could be the reasons?
Thanks.
Regards,
Krishnan.

Hi
There are a couple of things to tell you here.
Firstly LS24 - This shows one material only and you will see where this material is all over the warehouse.
Secondly there is an alternative if you want to see all materials and that is LX02 and in the st type field put *** and you will see everything in the warehouse and if you sort on the available qty field (descending I think but try both) all of your negatives will come to the top of the screen with the largest negative first.
Thirdly LL01 This will only show negative stocks for the storage types that have been included in the configuration for this. Also the negatives in LL01 will only appear after the amount of time you have set in the congiguration whereas in LS 24 you will see them immediately.
So for instabce if you set st type XXX to show negatives after 24 Hours you will not see them in LL01 for 24 Hours but they will be in LS24 AND LX02 immediately.
This does not mean that LL01 is wrong just that youi need to make some adjustments in the config and be clear as to what you want to see and when.
I hope that this helps

Difference Between Using MVC And SwingUtilities For GUI Component Update

Hi Guys,
What are the difference of using the MVC (Model View Controler) pattern to update GUI and using the SwingUtilities of doing the same job?
Are there any big differences or shortcomings of any?
Thanks.

Thanks.Your question is akin to asking, "What's the difference between using a car to get somewhere versus stepping on the gas pedal to do the same job?"
The use of SwingUtilities to update the "view" only pertains to updating components in a thread-safe manner, it has nothing to do with MVC. MVC would govern when the view gets updated (i.e. after the model changes), while SwingUtilties would be used to specify how the view gets updated.

BPM and webdynpro for ABAP

Dear All,
I am new to BPM and wanted to understand that is there any linking in Web dynpro for abap and BPM or WD for JAVA can only be used in BPM. Also can somebody help me with the stztart document which tells about transaction and SAP netweaver step by step process for creating SAP BPM application. The BPM workflow, how it is connected to SAP at backend.
Thanks in Advance!
Regards
Naveen

Hi Naveen,
Netweaver BPM is shipped as part of Netweaver Composition Environment starting version 7.1 EHP1 and now CE 7.2 is also out. It wont be possible to run on ABAP stack. Also if you want to start learning then you may start with the following links:

Webdynpro for ABAP ALV问题

我想在ALV加控制行翻页的，IF_SALV_WD_TABLE_SETTINGS~SET_DISPLAY_EMPTY_ROWS( abap_true ).
但就是不出来，还是只有旁边的下拉，请教大家怎么做？

你提到那个ALV的翻页控制行在新版本的Netweaver当中已经被滚动条取代了。SAP是应客户要求改动的。如果你不习惯，可以创建OSS呼吁SAP改回去:-) ，所以设定控制行的相关的方法都失效了。
如果你非要这个控制行，可以通过设定参数WDLIGHTSPEED和PAGINATOR来实现，但是你将失去大部分Webdynpro新功能，而采用兼容模式运行Webdynpro，严重不推荐。
建议你要求客户逐渐习惯这个改变。

Differences between SAP BO and SAP for Iphone

Hi,
Can someone tell me where I can see the relation of the releases between SAP Business one and the SAP BO for Iphone. Now testing, the stock of an item, the Iphone application is tell me that the release of the SAP server is not compatible with this funcitionality and I have to upgrade.
The point is that I just upgrade the customer, form 2007 to 8.8 PL19, and I don't really know if I only have to upgra the B1i and in which PL, or I have to meka the upgrade of all the components of SAP BO.
the release of the SAP for Iphone implemented is 1.2.0.
Thanks,
Cristian Moreno

Hi Cristian,
the recent docu for the App should give you the relevant info ([http://service.sap.com/sapidp/011000358700000483052011E/B1_MobileApp_Guide.pdf|http://service.sap.com/sapidp/011000358700000483052011E/B1_MobileApp_Guide.pdf]).
These latest functions of Version 1.2.0 (like stock per warehouse) of our SAP Business One Mobile Application require SAP Business One backend on Minor Release 8.81, Patch Level 05.
For reasons of backward compatibility mentioned system info has been installed.
regards, peter
