POWL problem

I have tried to create a POWL which is called from a WEBDYNPRO
However, on execution, I get a problem.
My Webdynpro is working, this is not the problem (tried to link a standard class (easy_powl_demo) to my type and this works)
The problem occurs when i execute the application on the following code
CALL METHOD <fs_type>-instance->get_actions
    EXPORTING
      i_applid          = m_applid
      i_username        = sy-uname
      i_type            = i_type
      i_selcrit_para    = i_crit_para
    IMPORTING
      e_actions_changed = e_actions_changed
    CHANGING
      c_action_defs     = c_action_def.
m_applid = ZHR_POWL_DEMO
sy-uname = my user
itype = ZTY_POWL_DEMO
i_crit_para = empty (this is also empty with the working demo version from sap)
The error i get is
Call of a method or kernel Method that has not been implemented.
Can anyone help ?

I solved it, there was no active implementation for the interface method get_actions. Just opened it and activated it. It is now working

POWL Accessibility problem

Hi,
If I switch on the accessibility for the POWL (by adding &sap-accessibility=X to the url), the screen reader displays an additional "Unavailable" string when positining the cursor to any of the table cells. E.g.: 0001 - Unavailable - 0001 - Row 4 column Plant. How could I remove the unavailable string? The tooltip is correctly set to the cells.
Thanks in advance,
David

Hello Neha & Kön,
thanks for your reply. It sounds very understandably that you cannot control the screen reader. Who could know it surly?!
Thanks also to Kön, this works fine but I think you can only set a focus to one element. the best solution for me will be to control the "tabways"(in which sequence the elements will be focused) and the ability to decide if elements are visitable.(and this should also work even accessibility is set) wow, i don't know

Portal Session Timeout - ICM/Webdynpro/POWL

Hi Experts,
We are having SRM Portal which has POWL Webdynpro and other applications running.
SRM Portal is a seperate JAVA Instance and integrated to backend with SSO enabled.
We have Logon Ticket Timeout set as default 8 Hours and the Session Timeout in Portal set as 2 Hours (Server>services>webcontainer>properties>Session Timeout).
For the ABAP backend, we have rdisp/plugin_auto_logout-->7200 (2 Hours) and ICM timeout as remommeded by SAP as icm/server_port_0 = PROT=HTTP,PORT=8012,TIMEOUT=90,PROCTIMEOUT=600
Now the problem is:
1. Users connected to portal and work on any POWL Iviews has an idle time of two hours-->we get the ICM session timeout error page.
2. Sometimes Users get the Login screen of portal within the Navigation Frame which can be identified as the Ticket Expiration
Is there a possibility to control the behavior of portal to avoid these error pages to Users like if the timeout happened in backend, there should be auto refresh if the user clicks the application.
And if the ticket expired, the portal should refresh to the home screen on clicking any Iview.
We tried the IDLE timeout pop up and in Vain, you could see my another post on the same.
Portal Idle Pop Up

Sethu

Hi,
Read SAP note 705013,
I think adjusting the kernel parameters, rdisp/gui_auto_logout and rdisp/plugin_auto_logout will help.
Try adding below parameters in the Instance profile.
icm/keep_alive_timeout 3600
icm/conn_timeout 5000

POWL OBN links do not open a pop up window in one domain

Hi
I am hoping to get some helpful information on a problem with a POWL OBN links not opening a pop-up only in one domain. The issue is described below.
We have deployed the BP for Buyer 1.0, SP15. One of the iViews we use is the My Purchasing Documents and we have enabled the query POWL_PR_MY. Our Portal Version is 7.0 SP21, ECC6 (no EHP).
Query POWL_PR_MY (My Purchase Requisitions) of POWL Application OPS-BUYER-POWL-PURDOC has links with the Purchase Requisition Number. Ideally when the links are clicked on, it should open up the Purchase Requisition transaction with the details of the item. This does not happen in our case.
Our Portal Server is on the domain main.nex.com, but is accessed from the domain drs.nex.com. The ECC is also on the main.nex.com domain.
When we access this application using "portal.main.nex.com", the links work fine as they should. But when we access the application using "portal.drs.nex.com", they do not open at all. There is no error message displayed. It just simply does not do anything.
We have added *.main.nex.com to our local intranet trusted sites and have enabled pop-ups, added the proxy exception
*.main.nex.com. All the Pop-ups are working from the other Custom Webdynpro application and from the other SAP GUI for HTML transactions in the portal from domain "drs.nex.com".
I am not sure what the problem is, but we are facing a problem ONLY with this application's links. I am not able to see anything in the nwa logs too.
Any pointers as to where I can look for issues?
Thanks
OJ

Hi Malte
No luck yet - so we are currently using portal.main.nex.com to access our portal until we find a solution. Will keep you posted. In the meanwhile, if you do find some information, please update.
Thanks

Issues with POWL action buttons and row selection after Support Packs

We recently applied ECC 603 Support Stack 16 to our environment and are having problems with some SAP standard POWL lists (example is KYKOP-OPS-MM-PO-W: Purchase Orders for Goods Receipt). In fact all of the POWL lists that we are using are behaving the same way. There are 2 changes that have happened after moving to this stack.
1. In order to select a row in the list, we now have to press ctrl + click, previously, just clicking the the row would select it and fire the OnLeadSelection
2. All of the Action Buttons in the POWL lists are disabled.
I have debugged the Feeder Class /KYK/CL_MM_FEEDER_PO and see in th GetActions method and see that the ls_actions-enabled is getting set to true, but for some reason the buttons are disabled when the list is rendered.
I've checked a side-effects report from OSS and have come up empty handed. Has anyone else run into this?
Eric

I have found an OSS note that addresses this problem. This problem will effect anyone who is using ALV for ABAP WebDynpro after applying BASIS Support Pack 20 for 7.0. The OSS note is 1363334. Question Answered.

Error adding custom field in POWL

Hi all,
I've added a custom field in POWL for SC.
The problem is when I fill this custom field and push the search button an error is displayed:
"Last query refresh failed due to internal errors; contact your admin."
I've seen there is a short dump in st22. SAPSQL_INVALID_FIELDNAME
I've seen that the select statement is being built dynamically (include LBBP_PDF80).
Within the conditions of the where clause is adding a line with the correct value but is adding another senseless line .
In the custom fields range is always adding a line like this; LOW = space OPTION = CP.
I don't know why. The problem is in the form GETLIST_CUF_ADD_LINE.
If I delete this second condition in debug mode is working fine.
I've tried to find some OSS note but I couldn't find any...
This are the steps I've followed to add the custom field in POWL:
- Add the field to structure /SAPSRM/S_SEARCHFIELDS. (with the same name that it have in st. INCL_EEW_PD_HEADER_CSF_SC )
- Add the field in view /SAPSRM/V_SRC_CR.
- Add the field in DB criteria in the transaction /SAPSRM/POWL_CUST.
- Use the report POWL_D01 for refresh the query.
Do you know what can be the problem?
Thanks in advance.

Which version of SRM are you using ?
Pls. check the attached note, which describes the similar problem :

New custom field in the POWL search criteria

Hi experts,
My requirement is to add a new custom field in the search criteria (Parameters)
In my Easy shopping card POWL. I need to add custom fields in search criteria.
I tried appending my custom fields in structure /SAPSRM/S_SEARCHFIELDS
And customized the POWL type DB criteria SAPSRM_FEEDER_SC by adding the custom field
But still the newly added search criteria is not displaying in the
Query SAPSRM_E_CHECKSTATUS_01 in powl_query transaction.
Kindly help me to solve this issue

Hello Konstantin,
thanks for the reply...
I tried to add an extra Field(Company code) in POWL Search. the problem is the Field Company code doesnt get updated in BBP_PDHSC and BBP_PDISC with the value used in while creating SC.
I only get the Company code value in table BBP_PDBEI for SC.
So when i give any value in POWL search for company code no data is shown even though the SC was created in the inputted Company code.
so how to go about adding CC as search criteria in POWL so that the resultant output is filtered on the basis of CC value.
Thanks

Exception UNKNOWN_ERROR while using GUI_DOWNLOAD in POWL

Hi,
I am trying to use FM GUI_DOWNLOAD to download an internal table in POWL to an excel sheet.
Using GUI_DOWNLOAD I get an exception 6 = UNKNOWN_ERROR.

POWL 'Query Name is already open in another session'

Hi there,
Our users are constantly getting the following error message when using POWL's in the Portal.
Query <Name> is already open in another session' (POWL 016)
The error occurs when a user tries to refresh a query and the query is locked in another session (ENQUEUE_EPOWL_QUERY_EDIT Exception foreign_lock).
There are various root causes to why this error happens, system, application, communication etc. The one I am seeking help on occurs when the user abruptly terminates the browser session (forced or unforced) and the orphaned session is unable to close properly leaving the POWL query locked.
We are currently informing the users to
1.) close all windows and reload the worklist.
and in certain circumstances
2.) log off and log on again
The above workaround doesnt always solve the problem. We are reluctant to give users access to SM12.
Has anybody encountered something similar, if so were their specific settings, notes, code etc. which needed to be implemented?
Cheers
John P

Try the following steps
Please implement the note 1836401 and the prerequisites 1873487,1902580 .
Identify the POWL Query name and set the refresh type as: 'refresh on every LIST VISIT'.
Important: Run the report POWL_D01 and remove the result list of your POWL
Application ID, it#s very important because the cache would still contain the old refresh type and will not recognize the new refresh type, please run the report at first for one user ant test the behaviour, if it works run it for all other user
Pass the application parameter REFRESHA with value X to your POWL application. After that retest your issue, it should work. if not implement the note 1975395 and its prerequisites and test again
Best regards,
Robert.

Link to action doesn't work in a POWL application

Hi,
I have developed a web dynpro ABAP application and it is called by portal,
This WD calls standard POWL, in a POWL there is a LinkToAction field.
When I click on field the system should open a new window (shopping cart detail),
but it doesn't happen anything.
which could the problem be?
Thank you.
Best regards.
Al

Hi Alberto,
1. Define an Action (corresponding to your Link to action which is typically the FIELD Name of the column in POWL Table) in your POWL feeder Implementation "IF_POWL_FEEDER~GET_ACTION" .
IF_POWL_FEEDER~GET_ACTION is a standard object of custom feeder class, how can I define a new Action?
<Vineet> See the Wiki Link http://wiki.sdn.sap.com/wiki/display/WDABAP/DocumentationInformationabout+POWL
This has a document (POWL.doc) for POWL, refer page number 20. You can use parameter C_ACTION_DEFS for explicitly defining Actions.
2. Handle the defined action in another feeder implementation "IF_POWL_FEEDER~HANDLE_ACTION".
this code could be rigth?
METHOD if_powl_feeder~handle_action.
FIELD-SYMBOLS: <shopping_cart> TYPE STANDARD TABLE.
IF i_actionid = 'SELECTION'.
triggers the event
e_portal_actions-fire_wdevent = abap_true.
Pass parameters to event
ASSIGN c_result_tab TO <shopping_cart>.
i_shopping_cart = <shopping_cart>.
selected row
READ TABLE c_selected INTO ls_selected INDEX y_index.
Read selected POWL data
READ TABLE i_shopping_cart INDEX ls_selected-TABIX INTO s_shopping_cart.
CHECK sy-subrc = 0.
Pass parameters
ls_parameter-key = 'OBJECT_ID'.
ls_parameter-value = 'I_'.
APPEND ls_parameter TO e_portal_actions-parameters.
ENDIF.
ENDMETHOD.
<Vineet> Seems good provided you have defined the action name in "your class->IF_POWL_FEEDER~GET_ACTION" as 'SELECTION'.
3. Now you need to raise an portal event from the method "IF_POWL_FEEDER~HANDLE_ACTION".
where a portal event has to be raised?
<Vineet> You have alrday raised it when you used "e_portal_actions-fire_wdevent = abap_true", as above you can additionally pass parameters as you have done in pushing some data in "e_portal_actions-parameters".
4. This Portal event will be again captured in the event "POWL_FOLLOW_UP" from POWL WD component "POWL_UI_COMP"
<Vineet>Let's assume your WD component is "MY_COMP" which uses "POWL_UI_COMP". then in the component controller or View you can handle an event "POWL_FOLLOW_UP" which is a POWL Interface event. This vene has the same action "SELECTION"a nd the parameters which you have raised from "your class->IF_POWL_FEEDER~HANDLE_ACTION".
5. You can handle this event "POWL_FOLLOW_UP" in your WD which uses "POWL_UI_COMP" and throw a pop-up from your WD component.
it is not clear point 5.
<Vineet> From the event handler of "POWL_FOLLOW_UP" you can launch another webdynpro in a po-up or a new winmdow.
Please let me knwo in case you face issue.
Regards
Vineet
thanks.
Best regards.

Problem with the math library functions

Hi,
I encountered a problem related to some functions provided by math library on sun. I narrowed it down to the following test program:
========================================================
#include<stdio.h>
#include<math.h>
void pow_res()
double x = 10.0;
double y = 2.5;
printf("pow(%.2e, %.2e):%.20e\n", x, y, pow(10.0, 2.5));
void cos_res()
double x = -6.433230338433114370e-02;
printf("x:%.20e cos(x):%.20e\n", x, cos(x));
int main()
pow_res();
cos_res();
return 0;
========================================================
The above test program has to be linked with any math library. It is �libm� for amd64/linux, but for sparc we have choice between �libm� and �libmopt�. I am compiling above program with "cc <test_program.c> <-lm/-lmopt>" command.
On sparc, if the above test program is getting linked with �-lm" then it gives same results for the �cos� on both amd64 and sparc, but gives different results (16th decimal digit onward) for �pow�. If it is getting linked with �-lmopt� then it gives same result for the �pow� on both the platforms, but gives different results for �cos�. Linux results match with the amd64 results.
The �Numerical Computation Guide� provided by SUN (ftp://docs-pdf.sun.com/802-5692/802-5692.pdf page 40, table 2.10 ) says that you can trust only 15-17 decimal digits for double calculation. But here the requirement is to match the sparc results exactly with the amd64/linux or at least match the result till 20th decimal digit. I guess it is something to do with the FPU setting either through compiler options or code. I tried many different compiler options, like -fast, different combinations of compiler options provided by -fast macro, but nothing helped.
Following is the system configuration:
Amd64:
gcc version: 3.3.6
OS: RedHat Enterprise Linux 3.0 U7 (Linux 2.4.21-40.ELsmp x86_64)
Sparc:
cc version: Sun C 5.8 Patch 121015-01
OS: SunOS 5.9 Generic_118558-21 sun4u sparc SUNW,Sun-Fire-280R
It will be great if somebody can explain the problem and the solution to get rid of it.
Many thanks,
Sunil

Transcendental functions are not specified to be correctly rounded in the same
sense as +-*/. So it's entirely possible, and often observed, that libraries of equal
quality deliver slightly different results.
To simplify, suppose one wanted to compute x = 4*atan(1.0)
which happens to be the
transcendental number pi which is roughly, in hex and in decimali:
.C90F DAA2 2168 C234 C... * 2^4 or 3.141592653589793239...
But binary floating-point arithmetic can only represent certain rational numbers of
the form of an integer of at most 53 significant bits times a power of two. The
nearest double-precision number to pi is
.C90F DAA2 2168 C * 2^4 or roughly 3.141592653589793116...
This particular number has a large but finite decimal expansion. And if you
do printf with %e.20 you will get the 20 decimal digits of that double-precision
number's expansion, not the 20 decimal digits of pi, which only agrees to the
15 significant decimals 3.141592653589793 and differs afterward.
In the case of pow(10.0,2.5), (which happens to be sqrt(1.0e5))
the correct result in hex looks something like
.9E1D 276F D4BA C410 C... * 2^9 or roughly 3.162277660168379332...E+2
in hex notation, while the closest double precision number is
.9E1D 276F D4BA C8 * 2^9 or roughly 3.162277660168379612...E+2
but it's only slightly closer than the next closest double precision number
.9E1D 276F D4BA c0 *2^9 or roughly 3.162277660168379043...E+2
Either answer is a good answer, and math libraries might that only aspire to
deliver results that are close to correctly rounded might deliver either, depending
on which approximation algorithm is used, which might depend on what's fastest
on a particular processor.
So why don't math libraries deliver correctly rounded results instead of almost?
Because the slight extra increase in accuracy doesn't do much good for most
people, and the major decrease in performance is noticeable by lots of people.
The main payoff of correctly rounded transcendental functions is that they
promote uniform numerical results across platforms, which is worth something
to some people but not much to many people.
So for those who find it worthwhile, there are correctly rounded transcendental
function libraries available. Sun's development version is available at
http://www.sun.com/download/products.xml?id=41797765
Another solution for some people is to change double variables and functions
to long double, using powl and cosl in the examples. That increases the
accuracy to almost 20 digits on x86 and over 30 digits on SPARC, and while
the same issues eventually arise, most users would never encounter them.
The SPARC long double implementation is in software rather than hardware,
and so entails a major performance reduction compared to double.
The Numerical Computation Guide at docs.sun.com discusses many of these
issues at greater length.

Some newbie POWL feeder class questions

Hi,
I'm just working with POWLs resp. the associated feeder class. At the moment I have two question that hopefully could be answered by someone:
1) Is it possible to modify the UI layout of the selection criteria in a way that they will be displayed in a configurable number of columns and not just one below the other?
2) I declared some criteria with "ls_seldef-kind = c_type_param.". The user should be able to work with wildcards for these criteria (option "CP"), but the criteria values given to the GET_OBJECTS method always do have the "EQ" option. This is not really useful for e.g. description fields. How can I change this?
Many thanks in advance for any help.

I also hope I can know how to do .
Pleae tell me if you have solved the problem .
Best regards ,

POWL :IF_POWL_FEEDER :2 Confirmation Messages

Dear All
We are implementing this POWL interface and overriding its GET_ACTION_CONF method as well to get the confirmation pop-up message .
However there is a new requirment to show another popup on clicking of yes button of this popup. I am not sure how can we do that . Is it possible for anyone to share some experience as how can we implement 2 confirmation messages in POWL though we only have one method available to us
Thanks and Regards

Hi,
I faced with the same problem and I found the class CL_POWL_RUNTIME_SERVICES (POWL runtime services) using the follow methods:
GET_CONTENT_VALUES
SET_CONTENT_VALUES
Example:
Data:
    L_PARAMETER_VALUE TYPE STRING,
    ST_ADDITIONAL_PARAMETER TYPE POWL_NAMEVALUE_STY.
CL_POWL_RUNTIME_SERVICES=>GET_CONTENT_VALUES(
    EXPORTING
      I_PARAMETER_KEY   = 'ACTION_VIEW_ID'
    IMPORTING
      E_PARAMETER_VALUE = L_PARAMETER_VALUE ).
If not L_PARAMETER_VALUE is initial.
    ME->GC_ACTION_REQUEST_VIEW_ID = L_PARAMETER_VALUE.
else.
    ST_ADDITIONAL_PARAMETER-KEY = 'ACTION_VIEW_ID'.
    ST_ADDITIONAL_PARAMETER-VALUE = GC_REQUEST_VIEW_ID_INBOX.
    CL_POWL_RUNTIME_SERVICES=>SET_CONTENT_VALUES                                                                         ( ST_ADDITIONAL_PARAMETER ).
    ME->GC_ACTION_REQUEST_VIEW_ID = GC_REQUEST_VIEW_ID_INBOX.
endif.
Keep it in mind, if you have on or more POWL's queries, the parameter's value will be shared for all them.

Search Criteria not working in POWL

Hello Experts,
I have added the new fields in POWL Search Criteria using the Add custom field to SC and POWL.
but after adding the fields when i try to search using the input made by the user the resultant output is always blank and also there is no data being displayed in the newly added columns.
Please help me so that the correct output gets generated after the user input and the newly added columns are not empty.
thanks.

Hello Konstantin,

I tried to add an extra Field(Company code) in POWL Search. the problem is the Field Company code doesnt get updated in BBP_PDHSC and BBP_PDISC with the value used in while creating SC.
I only get the Company code value in table BBP_PDBEI for SC.
So when i give any value in POWL search for company code no data is shown even though the SC was created in the inputted Company code.
so how to go about adding CC as search criteria in POWL so that the resultant output is filtered on the basis of CC value.
Thanks
Rajat
