ALV filter with own logic

Hello colleagues out there,
I have a request from my users concerning ALV filtering. They want to have filters of the kind :
- A = 5 or B = 6
- A + B > C
(A, B, C Columns of the table)
Surely I can implement such rules "hard" coded in the ABAP. But my question is: Is there are more generic way, that allows the users to define their filter rules themselves without having to modify my programs ?
Many thanky for your help
Rabanus Diehl

Hi rabanus,
1. A = 5 can be done
B = 6 can be done
but OR conditions, between two fields cannot be done,
in standard alv filter functionality.
2. A + B > C
cannot be done,
bcos it allows filter only one one field, by one field,
not
using some expressions/equations.

ALV GRID with own EXCEL-Template

Hallo,
I have Problem with using ALV-Grid with a own created
template.
At First I copy the SAP_OM.XLS template to CUS_OM.XLS.
Then I update it by deleting all sheets, but not RAWDATA.
When I use this template in ALV-GRID, it would be the right one, but it his no Data.
The security settings in Excel are correct.
Can anyone help me to show the data like the normal
ALV-GRID??
thanks Dieter

Adding mandatory filter with own LoV to BW OLAP Universe

Dear all,
I want to add a own filter with custom LoV to a characteristics-filter in an OLAP Universe. This filter does not exist in the BEx Query, so I have to do it manually.
So when the prompt shows up in WebI, the User should be able to select the Values from the custom LoV, for example:
- Tokio
- London
- Paris
The filter has to be mandatory and Tokio should be preselected. I was testing some things with the filter-XML, but always got errors. Can somebody tell me how this works?
Thank you for help in advance!
B. Wegner

Hi,
There are a few steps involved, I would suggest approaching them one at a time.
First, try to set up a filter (condition in the universe) to only show data for Tokyo (no prompt). Ensure you can get this to work.
Next, try and turn this condition into a prompt, but just define the LoV in the prompt syntax, not a separate object. Check that this works.
Next, try and split out that LoV into it's own object that populates from the characteristic in the BEx query. This will be the tricky part (maybe), if possible, get a filter created in the BEx query (make sure it's set as 'ready for user input') so that you see how the LoV gets created.
As a last resort, have a look in the manual: http://help.sap.com/businessobject/product_guides/boexir31SP3/en/xi31_sp3_sap_olap_univ_en.pdf
Hope that helps.

How to creat CS-order with config service product with own logic

Hi all,
I saw already different threads related to this topic, however no clear solution was given yet.
The scenario is:
Create from a notification list the service orders and determine in the background a correct service product which is configurable. Via an own logic the service product is found in a z-table and and the configuration is done via a seperate logic.
What would be the solution of the above scenario.
I already found some information in using:
CUCB_GET_CONFIGURATION
CUCB_SET_CONFIGURATION
CUCB_CONFIGURATION_TO_DB
But does this work?
How should the logical flow be in using these functionmdules.
We are using BAPI_ALM_ORDER_MAINTAIN to create the service order, however it is not allowed in this bapi to enter a service product which is configurable.
Thanks for your input in this.
Best regards,
Pascal

How to filter standard ALV report with custom UI element?

Hello Expert,
I got a requirement to filter standard ALV report based on the custom UI element (which is created in the screen before displaying the ALV report). Upon entering the values in the Custom field, the ALV report is displayed accordingly.
Any ideas how to approach it?
Thanks,
Mohammed

Hi,
Okay, let me explain the steps in detail
Let us say you have alv table with 10 records and alv table is shown first time with all 10 records
Create an internal table in component controller's attribute GT_ORIGINAL_DATA and save all 10 records into this table first time
Now, user enters value in FILTER_MATNR field 123 and press apply_filter button or press enter key
Read the value of field filter_matnr and get the only matching records from global internal table GT_ORIGINAL_DATA into local internal table as below
          data lv_matnr type matnr.
          data lt_data   like wd_comp_controller->gt_original_data.
               " read the value from context attribute of filter_matnr
                    lv_matnr = ???
               " copy all data into local table
                    lt_data[] = wd_comp_controller->gt_original_data.
               "delete the records which does not match
                 delete lt_data where matnr NP lv_matnr.
Now, bind the data lt_data to context node of alv table
Hope this helps you.

Problem with ALV filter functionality when filtered for multiple values

Hi,
I am facing a problem with ALV filter functionality.
I have displayed an ALV with some columns col_A, col_B and col_C
col_A---- col_B -
col_C
1----
a -
abc
2----
b -
pqr
3----
c -
lmn
4----
d -
xyz
5----
f -
stu
From the settings link I am applying filter on column col_C and selected multiple values say 'pqr', 'xyz' and 'lmn'.
Now the ALV is showing rows only for last selection i.e . results are fetched only for value 'lmn'.
i.e. after applying the filter the ALV table looks as below:
col_A---- col_B -
col_C
3----
c -
lmn
But ideally it should be:
col_A---- col_B -
col_C
2----
b -
pqr
3----
c -
lmn
4----
d -
xyz
I could not find any OSS note related to this issue.

Problem with alv filter

Hi all,
I have a problem when i filter ALV column, which has data type BELNR (FI doc No). I input in filter FI doc: 40000007 (8 char long, w/o zero ahead), then i get the empty result. The really one i want to get is a ALV line with FI doc = '40000007'.
Could u pls help me?
Thanks and regards,
Hung.

Check the field catalog for field BELNR, it should have conversion exit ALPHA. (check your report or execute [The Consistency Check|http://help.sap.com/saphelp_sm32/helpdata/EN/d6/23253963143e6ae10000000a11402f/frameset.htm])

F4 Valuehelp with own dataelement in ALV

Hi out there,
i createt own dataelement with own domain. in domain there are fixed values.
Now i designed an itab for alv grid. (abap oo methods).
Unfortunately the F4 Help does not appear.
How to config the corresponding fieldcat?
CLEAR ls_fieldcat.
ls_fieldcat-ref_table = '<Name ITAB>'.
ls_fieldcat-fieldname = '<Name Column in ITAB>'.'.
ls_fieldcat-DD_ROLL = '<Name Dictionary Element>'.
ls_fieldcat-F4AVAILABL = 'X'.
ls_fieldcat-edit = 'X'.
APPEND ls_fieldcat TO pt_fieldcat.
Unfortunately nothing happens. Just empty valuehelp.
I testet the ddict-elem as selscreenparameter...and valuehelp appears..

Thanks!
I already got my f4 help. It's not a dynamic one. Jaust a custom Dataelement depending on Custom Domain WITH FIXED VALUES.
I suggest its not neccesary to use eventing etc. Just ddictfunctionality in alv grid.
I tried with
ls_fcat-inttype = <name DDICT Element>.
Like in BCALV_EDIT_08.
No Effect.

I don't actually own Logic Express, but...

I don't actually own Logic Express, but I figured this would be a better place to ask my question.
My question is regarding dither.
I understand that dither, when it's all said and done, is simply low-level noise to keep truncated bits from sounding like butt when you reduce the word length of a recording.
Can one, in theory, use any form of consistent noise as a form of a dither signal such as, for example, the gentle hiss of an audio cassette?
I use this particular example because I happen to love the sound of tape hiss.
Also, does one need to dither if the bit depth is never changed/reduced/increased if one if editing between two different audio editing programs? I record my tracks using GarageBand and I mix, finalize, etc. using Pro Tools and I add no type of effect or normalizing or anything other than light automation and tasteful mixing. Do I still need to dither even if my Pro Tools mix-down session is set to 44 kHz/16-bit?
Thanks for any help anyone provides.

If you're not changing the bit-depth or sampling rate, you do not need to dither.
Dithering adds a very low level noise signal so as to avoid persistent and predicatble rounding problems but it's not the best way of adding hiss to a recording. If I'm doing a sound effect (perhaps a cassette playing back in a TV scene), I go to my stock library and find cassette tape hiss and add it to the mix (as a separate track). You could just add white noise with a band pass filter with quite high centre but it's not the same - it's just too random.

Hoe to creat own logical database inhr

hi all,
can anyone send the codefor creating the own logical databse like pnp in HR.

Creating a Logical Database
Open the Logical Database Builder (SE36)
1. Enter a name on the initial screen of the Logical Database Builder and choose Create.
2. A dialog box appears. Enter a short text. You can change this later by choosing Extras -> Short text or Administration info.
3. Once you have entered the short text, you must define the root node of the logical database. Enter the node name and its attributes. There are three different types of nodes:
The logical DB gets created.
Then to edit the logical DB, use the following steps.
The structure editor of the Logical Database Builder appears. On the left is the name of the root node, followed by a code for the node type: T for a database table, S for a ABAP Dictionary type, and C for a type from a type group. The new logical database now has a structure with a single node.
You can now extend the structure as described in Editing the Structure.
If you choose Next screen (right arrow in the application toolbar), a screen appears on which you can enter a search help for the logical database as described under Editing Search Helps.
If you choose Next screen (right arrow in the application toolbar), a dialog box appears, asking you whether the system should generate the selections for the logical database. When you have confirmed the dialog box, a list appears, on which you can select all of the nodes that you want to use for field selections or dynamic selections. The fields that you select are included in the source code generated by the system for the selection include.
The generated selection include is displayed in the ABAP Editor. You can change it as described in Editing Selections.
If you choose Next screen (right arrow in the application toolbar), a dialog box appears, asking you whether the system should generate the database program for the logical database. The database program is generated from the structure and the selection include. It has a modular structure, consisting of several include programs and all of the necessary subroutines, with proposals for the statements that will read the data.
The generated database program is displayed in the ABAP Editor. You can change it as described in Editing the Database Program.
If you repeatedly choose Previous screen (left arrow in the application toolbar), you can display and change the general attributes of the logical database.
Finally, you can maintain optional selection texts and documentation.

Check Interactive report filter with APEX item :P101_USERNAME

Hi,
is there a way to create a filter with IR which is based on the :P101_USERNAME item?
I use this variable with the windows user name and want to show only rows where the current user works with.
Thanks ahead,
Tobias

Hi John,
my plan was to reference the filter on the user level.
Parts of selection for the IR:
SELECT r.r_id,
c.c_name,
r.r_note,
UPPER(r.win_account)
FROM requests r, classes c
WHERE r.r_c_id = c.c_id
Info:
WIN_ACCOUNT looks like: ARNHOLD_TOBIAS
:P101_USERNAME looks like: ARNHOLD_TOBIAS
The goal is that a user in the standard view sees only his rows/calls and if he want to see the rows/calls from the colleagues too. He/She would only need to take off the filter for the USERNAME.
I could use my own items with an extra region too but I thought that there was an easier way then that.

Thanks.

Hi Linda,
Take a look at this sample program. The logic to handle any interaction with the user is in my "PORCESS_USER_COMMANDS" routine.
This is defined in the "I_CALLBACK_USER_COMMAND" parameter in the ALV FM.
Hope this helps.

Hi,
Use the fuction module 'ICON_CREATE' as follows.
CALL FUNCTION 'ICON_CREATE'
    "To create Red/Yellow/Green traffic icons
      EXPORTING
        name   = wrk_light
      IMPORTING
        RESULT = ip_status.
wrk_light can be;
'ICON_RED_LIGHT'
'ICON_YELLOW_LIGHT'
or 'ICON_GREEN_LIGHT' according to your scenario, that you can use the logic for your scondition.
Use it in PBO.

ALV report with dynamic columns, and repeated structure rows

Hey Guys,
I've done some ALV programming, but most of the reports were straight forward. This one is a little interesting. So here go the questions...
Q1: Regarding Columns:
What is the best way to code a report with columns being dynamic. This is one of the parameters the user is going to enter in his input.
Q2: Regarding Rows:
I want to repeat a structure(say it contains f1, f2, f3) multiple time in rows. What is the best way to do it? The labels for these fields have to appear in the first column.
Below is the visual representation of the questions.
