Change item value by process in DML Form: best practice?

Hi,
i have a working DML Form and would like to build an option for choosing values in a popup window and refreshing the page items after closing the popup window.
the DML Form has a button which opens the popup window with
javascript:popUp2('f?p=&APP_ID.:210:&SESSION.', 600, 580)
the popup window has a javascript function under HTML Header
<script language="JavaScript">
function passBack2()
doSubmit();window.opener.doSubmit();window.close();
</script>
and a button which called the javascript function
javascript:passBack2();
while the user chooses a new value and closed the popup window an application item holds the selected value.
the following page rendering of my DML Form use the application item in before header computations to get the new values.
from the developer toolbar's session link i found the values changed by the computation correctly and signed with 'I' but they will not displayed in the page and will not used in the Automatic Row Processing update.
how to accomplish this?
Michael

Michael,
while the user chooses a new value and closed the popup window an application item holds the selected value.
How does that happen, with an after-submit process on page 210?
the following page rendering of my DML Form use the application item in before header computations to get the new values.
All your popup page does is submit itself and then submit the calling page. There is no invocation of the before-header computation on the calling page in this sequence. You should use an after-submit computation.

Change item value when a specific item has changed... how can i do that?

Hi guys, i need to ask something...
Is it possible to have a process or a computation, that gives value to an item, only when one specific item has changed.
I have other items on my page too, but this two are related, and i need to give a specific value to the first one, only when the value of the second has changed...
Help please
tsveti:)

Hey Farhan, i guess i need some help on that easy javascript...

So in 'HTML Form Element Attributes' for the second item I m trying this :
onchange="javascript:{document.getElementById('P1_SUBPROJECT').value = '-1';}"
but when i change the value of this second item, the first one (P1_SUBPROJECT) dont get -1
what am i doing wrong?

Developer 10g Capture All CHANGED Item Values

Still learning this application one module at a time so be kind :)
What is the most efficient way to capture all the data block item values that have changed on the form at say the pre-update trigger?
I'm thinking of testing for:
RECORD_STATUS = 'CHANGED'
and if true then assign the first item to v_item using:
v_item := 'block_name' || '.' || get_block_property('block_name',first_item)
Then loop through each item in the block and test the DATABASE_VALUE against the form value and if they are not equal the assign the DB value to a variable and the form value to a variable and build a string of text to be displayed to the user by using:
IF GET_ITEM_PROPERTY(v_item,DATABASE_VALUE) <> :BLOCK_NAME.ITEM_NAME THEN
v_dbvalue := GET_ITEM_PROPERTY(v_item,DATABASE_VALUE);
v_frmvalue := :BLOCK_NAME.GET_ITEM_PROPERTY(v_item,ITEM_NAME);
v_string := v_string || 'Old value was ' || v_dbvalue || ' and new value is ' || v_form value;
Then advance to the next item by resetting the v_item variable to the next item using:
v_item := 'BLOCK_NAME' || '.' || GET_ITEM_PROPERTY(v_item,NEXTITEM);
And repeat the process until there are no more items in the block:
EXIT WHEN 'BLOCK_NAME' || '.' || NULL;
So what would be the most efficient way to do this?

The form holds information that is inserted by a technician then the manager of the technician has to approve the info and submit it to the director for final approval.
So what I do is capture any of the changes that the technician makes and put that sting into an email and send it to the manager so they know that changes were made to the record and they can approve or decline the changes before submitting it on to the director.
My successful POST-UPDATE trigger at the form level ended up like:
<<
p_html := 'Catalog item ' || :ITEMS.MANUFACTURER || ' - ' || :ITEMS.MODEL_DESC || ' ' || :ITEMS.MODEL || ' has been modified and the results are as follows: <br> ';
v_item := 'ITEMS' || '.' || get_block_property('ITEMS',first_item);
<<item_loop>>
loop
exit when v_item = 'ITEMS' || '.' || null;
v_dbvalue := GET_ITEM_PROPERTY(v_item,DATABASE_VALUE);
v_itemname := GET_ITEM_PROPERTY(v_item,ITEM_NAME);
v_block := 'ITEMS';
v_name := v_block || '.' || v_itemname;
v_frmvalue := NAME_IN(v_name);
IF v_dbvalue <> v_frmvalue THEN
p_html := p_html || 'OLD VALUE WAS: ' || v_dbvalue || '<br>AND NEW VALUE IS: ' || v_frmvalue || '<br>';
END IF;
v_item := 'ITEMS' || '.' || get_item_property(v_item,nextitem );
>>
The p_html variable is the string that I send to the email package to send out via our mail service.
Maybe this will help someone with a similar need.
Cheers,
Max

Change item value before commit

Hello,
I have a form in which I issue an execute_query from a mouse click to retrieve database values from a data block onto a form. The user is then able to change the values of these items on the form and commit them via a button on the form. What I want to do is make sure that some of the values, based on another item in the block, are negative and if not, change them to a negative value. before the changes are commited. I can't seem to find the right trigger to accomplish this-- has anyone have an idea on how to do this?
Thanks in advance.
Jeff

Hi,
How about putting your code in :
1. Pre-Update or
2. When-Database-Record
[Block Level trigger]
The trigger text could be something like :
If (:block.col is > 0 ) Then
:block.col := :block.col * -1;
End If;

Changing Item Values before saving Purchase Requisition in me51n, set_data function

Hello,
        I have written a user exit, which is called whenever changes are made to a purchase requisition. User Exit is MEREQ001 , function module EXIT_SAPLMEREQ_010 . My requirement here is that the Requisitioner should be 135 for every PR item under certain conditions. Therefore whenever there is any change made to the PR, before saving the PR item, I need to set the Requisitioner to 135, give a status message saying that the Requisitioner is set to 135 and save the Pr with the changed values. Following is the code I have written in EXIT_SAPLMEREQ_010. However, the set_data function called below does not change the PR values. Pls help
data: lt_item type mmpur_requisition_items,
       wa_item type mmpur_requisition_item,
       wa_itemdet type mereq_item,
       wa_itemref type ref to if_purchase_requisition_item,
       w_message type i.
constants: c_135 type afnam value '135'.
call method im_req_header->get_items
     receiving
             re_items = lt_item.
    loop at lt_item into wa_item.
     wa_itemref = wa_item-item.
     wa_itemdet = wa_itemref->get_data( ).

       call method wa_itemref->set_data( wa_itemdet ).
     endif.
   endloop.
IF w_message = 1.
    MESSAGE 'Requisitioner defaulted to 135 for all items' TYPE 'I'.
ENDIF.

Hi Sachin,
           I am able to get a reference to if_purchase_requisition_item in my code (wa_itemref ) and am also able to access each of the line items in the PR in the work area wa_itemdet.
At this point in the code ( wa_itemdet-afnam = c_135 ) , the work area value is set to '135', However, call method wa_itemref->set_data( wa_itemdet ), does not change the values of the work area wa_itemdet . Pls help

Re: open popup window and passing parameter to the popup
When I look at the session on the popup page, the value is still not passed and

(Swing) Reading fields from other forms - Best practice

Hi All,
I have been learning Java and Swing through NetBeans (quite a cool way to do it). I would like some 'best-practice' advice please. Google and search on this forum are normally my friends, can't find anything relevant for this though. I have created an application that seems to be functional, all my navigation is through tabs.
To make my app portable I have created a ?Settings? part. To save having another tab, I have basically copied the way NetBeans deals with opening the ?About Box? in its example, and have set-up fields in here. This essentially opens a JDialog with fields through an option in the menu.
I figure the best way to store the data is in a simple text file, and have the application read the values on start-up? Then when somebody changes the fields and saves it just overwrites the text file with the new values. I am not sure how to best read these in though, I can?t find a way of reading direct from the JDialog (i.e. var.getText()) which makes sense as the JDialog will be closed.
Will my best practice simply be writing a class which reads the file, then whenever I need a value just calling the class?
Thanks a lot

You should not be using preference files unless you really know what you are doing. This is one area of the very few areas of Java programming that can have lasting nasty negative affects on a computer that runs the code if done wrong.
If you want the user to save preferences it is better to just use xml. The advantage of preference files is they can be used by multiple programs and are permanent even after the program is done running/deleted/writen-over/forgotten. The disadvantages of preference files is they can be used by multiple programs, are permanent even after the program is done running/deleted/writen-over/forgotten, can cause damage to your OS, may be seen as harmfull by add blockers and/or anti-virus software, may lead to conflicts with other software that uses similar naming schemes, and are pretty much unportable.
You are going to be much better off in the long run learning XML and just saving them there, an added benefit of XML is if you screw something up and it causes your program to no longer run you can easily edit the xml by hand.

Arranging fields in a table-like form: best-Practice-Solution wanted

Hello Experts,
I´m wondering if there exists a 'best practice' considering how to arrange fields in a table-like form.
I know about cross-tables, but that´s not what we need. Most of the requirements that I have come to known are just that certain fields should be put in a certain order in a table-like outfit.
We have tried to do this using the drawing functions (e.g. putting a square around the fields and certain border styles), but it often happens that the lines overlap or there are breaks between the lines, so that you have to do a lot of manual configuration with the 'table'.
Since this is a requirement I´ve come upon with many reports, I can´t believe that this is supposed to be the best solution for this.
I don´t understand why there isn´t a table-like element in Crystal Reports to use for this. E.g. put a table with x rows and y columns in the header or group head section section and then just put the fields in it.
Many thanks in advance for your help !

Hi Frank,
You can use build in templates available in Template expert.
Click on Report menu-> Template Expert.
Select the desired template. ( Table grid template would suite best here) and click OK.
There is no facility of inserting a table directly as you said. You will have to do it manually by using lines and boxes.
Hope this is helpful.
Regards

Change item value at Sales Invoice form before create a document

HI,
I am trying to change value for "TrackNo" item on the sales invoice form just before create a sales invoice,
I have the following code:
Dim oForm As SAPbouiCOM.Form
Dim oItem As SAPbouiCOM.Item
Dim oEdit As SAPbouiCOM.EditText
Dim periodo As String
Dim sf As String
Try
   oForm = Nothing
   oForm = entorno.Forms.Item(FormUID)
   oItem = oForm.Items.Item("251")
   oEdit = oItem.Specific
   oEdit.String = "Y"
Catch
End Try
It seems to work only If i have selected the logistics folder ( the folder where the "TrackNo" Item is located)
If I have selected another folder as "contents" or "Accouting" when I create the document it fails.
Can you help me with this problem?
Many Thanks

Buenas Sergio,
Try forcing a click event on the logistic folder. I don´t think there is another option. You are only able to asign the value if the control is visible(and editable).

Item Master Data Best Practice

hello all
we are now using SBO for more than a year, and yet we still always add new items in our item master data. what is the best practice on maintaining the item master data. for you to understand this is the scenario. since in the Factory/Mill there are a lot of spare parts and equipments there, if some of this equipments is damage, we have to buy a new one, here the problem occur because if it only differ in Part Numbers we use another item code for it. with this practice, at later part we found out that we have more than 1 item code for only one item because of the naming convention. so we have to hold the other item code and use the other one coz we cant delete it anymore. sometimes 1 itemcode occurrs only once in the in the item history.
please suggest what is the best Practice on this matter.
1. Item Grouping
2. Naming Convention
etc..
NOTE:
our goal is minimize adding of items in item master data.
FIDEL

FIDEL,
From what I understand, you have to replace broken / damaged component of an item like Bulldozer, Payloader and mill turbines. This is the reason why you defined the parts as a new item.
From your Item code examples, I am not clear why you have 2 different names for the same item. and also what you mean by "this two item codes are actually the same,
If you are just buying parts to replace components and if you do not need to track them then I would suggest you create generic itemcodes in the Item master and simply change the description when you buy / sell them.
Example: Same Item different description.
REPL101 OIL FILTER
REPL101 FUEL FILTER
REPL101 xxxxx
This way you are not going to keep creating items in the database and also you can see the description and know what it was.
Simply change the ItemName in the marketing document and instead of pressing Tab to move to the next column Press CTRL+Tab so that SAP does not auto check then ewly typed name against the item master.
Let me know if your scnenario is otherwise
