Transfer tables between workflow container and BSP

Hi experts,
I've a BSP which I call from a workflow. I connected the workflow with the BSP through the use of transaction wf_extsrv. This all works perfect, only I can't transfer internal tables, multiline container elements or strings that are longer than the max. CHAR255. This raises a problem:
In my BSP I've a text box where a user can fill in a rejection reason. I want this filled textbox transferred back and forward bewteen my workflow and my BSP.
Does anyone have a solution to this problem?
Thanks in advance.
Kind regards,
Joost van Poppel

Hi Martin,
Tanks for you reply. I was already thinking this would be the easiest solution, so I applied it like you suggested.
The transferal is done by connecting the BSP via wf_extsrv through characterstrings. From this transaction I generated a task and connected my wf container to the container of the generated task.
I suppose there are also other options like Karri suggested. Haven't tried it yet to use SAP_WAPI_WRITE_CONTAINER, but will take it into account the next time I run in to the same situation. So Karri I also want to thank you for answering. It probably will be very useful in the future.
For now it is just one text box, so it is managable to give the text box back as seperate lines.
Kind regards,
Joost van Poppel

Place the photos into iPhoto on your Mac. Then when syncing your iPhone using iTunes, clock on the "Photos" tab behind your iPhone's summary tab and make sure the sync instructions are set correctly.

Can we pass Internal tables to workflow container?

workflow container has a size limitation, we need to pass any infotype to the workflow container, so can we pass internal tables to workflow container or is there any alternate solution?
Thanks in Advance

How do you configure the iMac so separate users can access each other's files, especially iPhoto and iTunes? I need to be able to transfer media between two users and not just gain limited access using 'share'.

Portal eventing between WD java and BSP popup

Hi guys,
I have a WebDynpro application that opens a BSP popup like that :
WDPortalNavigation.navigateAbsolute(
          wdContext.currentURLElement().getEvaluationURL(),
          WDPortalNavigationMode.SHOW_EXTERNAL,
          "directories=no location=no menubar=no resizable=yes status=no toolbar=no",
          "evaluationdeformation",
          WDPortalNavigationHistoryMode.NO_DUPLICATIONS,
          urlParam.toString()
When the popup is closed, I want to update the content of my webdynrpo application. I tried using portal eventing but it didn''t worked because the popup doesn't seem to know its opener....
Is anybody have an idea ?
Thanks in advance.
Julien.

Hi Julien,
have you made sure that your BSP application is using EPCF? There is a flag you need to set to X in your BSP app for this to take effect. Also, you can not add javascript to a WD app, so calling the window.opener will not make any difference. However, you can subscribe to an event raised by another application in your WD app. It is possible to raise events between windows, one being a bsp and the other a WD or portal application. Check the following threads.
[Portal Eventing: EPCMPROXY calls between two browser windows;
[Client side eventing between MSS teamviewer and BSP application;

Database table for Workflow Container values

hi,
I am on SAP ECC 6.0
I am trying to find workflow id number starting from document number
I try to find database table which has containe values of the workflow instances so that I can get workflow/workitem instance numbers for the document
this is custom workflow and it is not based on business object type. so checking container values is the onlyway I can get the workflows
but I am not able to find any table for it
I have checked following
SWW_CONT
SWW_CONTOB
SWWVCONTWI
SWXML_CONT
SWJ_CONT
SWJPCONT
SWJSCONT
SWPCMPCONT
SWU_CONT1
SWUOCONT1
almost all the SWCONT tables
Morever I put St05 trace to see all the tables in database operations while triggering the workflow
but the only tables seen here are
SWWHRINDEX
SWD_CONT
SWWWIHEAD
SWWCNTP0
SWWLOGHIST
SWWWIRET
SWWCNTP0 is Workflow Container: XML Database (P0)
but it is XML structure data. so its of new use to query container fields.
is this reason because of any workflow design or system config ?
how to read container values from database tables in such case?
thanks
bhakti

Hi,
>i need to display an ALV list with list of invoices and whether the workflow is awaiting / approved / rejected for review / approval. and who did the approval / rejection action
This you should be able to read from container now, if you have FIPP instance.
>the workflow has two steps - review and approve and so i would query table swwwihead for the parent id of workflow and then based on task number see which is ready status task and find if its awaiting approval or rejection
Don't do any selects to SWWWIHEAD unless you have some really specific reason. Just use SAP_WAPI* functions. You should be able to get each depended work item etc. easily with the standard functions.
>apart from this, several data like amount values, reference document, creation date and whole lot of invoice item and header level data is required which needs to be taken from workflow container
Why would you read this data from container? This data is in the SAP tables VBKPF, etc. There should be even functions to get all data related to an invoice - try to search for example with READPRELIMINARY* (read preliminary invoice).
In general:
1) if you have invoice number, get all related work items with a SAP_WAPI* function
2) if you have only the top WI ID, use SAP_WAPIDEPEND function to get the depended work items
3) with above function you probably will get also the status of the tasks / work items, so you don't need select in SWWWIHEAD
4) Now you have the "status" and the workflow data for the invoice
5) read the invoice data from standard FI tables (unless there is some specific reason to get it from WF container, and if there is, then I think that you might be having some fundamental problems in your design)

Relationship tables between header item and subitem in CRM

Hi Everyone,
I am using an E-commerce application where we have the porduct catalog consisting of header items and sub items.
While creating an order, if the header item has a subitem it displays automatically.How can i know that this subitem should be displayed for this particular header item. I mean to say, I just want to know the CRM tables where the relationship between header item and subitem are maintained?*

Hi,
Go through the CRMD_ORDERADM_H and CRMD_ORDERADM_I.
Pass header guid into CRMD_ORDERADM_I table in the HEADER field you will get corresponding item details.
If you want ot know sub items related to header pass your CRMD_ORDERADM_H table guid in the CRMD_LINK in guid_hi field you will get corresponding sub items fof your header.

Slow transfer speeds between Mac Pro and Shared Drive on Windows Domain

Hi Guys,
Getting really slow transfer speeds when I try and transfer a file from a Mac Pro to a shared network drive on one of our Windows 2003 Servers.
The Mac Pro is logged on to windows domain. This data is transferring via our hard network, not via wireless. Not having any other transfer speed issues on any other PC's.
For example an 8mb file took around 45 mins.
Hope you can help. Many Thanks.

I saw this at a site where they were using DFS with Server 2003. When the few Mac's they had connected to the actual server and uploaded the file it was okay. But when it was sending the file via the \\DFS_node\share_name the Mac took heaps longer for the same file. Watching the Activity Monitor > Network monitor you could see gaps with the data transfer, as if there was some pausing between packets. A pcap showed that there was constant DNS requests coming from the Mac, even after the connection to the share was made. The same wasn't happening when the connection via SMB was directly to the actual file server. As there was only a few Mac on site they left it with the direct connection but were getting an MS specialist in to look at it. Never heard what happened with that one but you may want to try monitoring the packet transfer to see if the data movement is contstant or breaking. I'd also recommend getting Wireshark to monitor the transfer. You can compare upload to download and maybe even the transfer from the Mac to an MS workgroup share.

File transfer errors between WP8.1 and W8.1

This is probably in the wrong forum. But I cannot find anything which this falls under.
Also please forgive my lack of competence in filing an issue like this.
I own a Lumia 1020 and was trying to move photos off my phone to laptop. More specifically was trying to move the DNGs. I had already moved the jpegs. When it came to cutting or copying the DNGs I keep getting an unknown error saying that the operation would
not work. (sorry I don't have a screenshot of the prompt)
Now, I decided to restart my phone and lo and behold that batch of DNGs are now lost. Which I must say is quite a bad thing given that those photos were rather important.
Since that cannot be undone, I decided to move the other DNGs which to my surprise actually did start the transfer process without any hiccup. But, when my phone went to sleep it seemed to sever the connection between my laptop and phone thus killing the
file transfer process and generally 'unplugging' itself from my laptop until I unlocked it again.
Again I'm not sure how to submit this or under what category it falls. But this is an issue which shouldn't be happening with the finalised version of WP8.1

What is the difference between WORKFLOW API and BPEL PROCESS MANAGER API

Hi,
I am using BPEL process manager and would like to know the correct api set.
I found the workflow api which appears to be part of the oracle workflow.
is workflow api and oracle BPEL process manager two seperate products? --- Pls confirm/deny.

Hi me_sun, me_oracle :)
The bpel api can be found here
http://download.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/toc.htm
workflow found here
http://download.oracle.com/docs/cd/E12483_01/integrate.1013/b28985/toc.htm
when us install BPEL you do get BPELs human workflow component. This is different to the Oracle Oracle workflow which was based on the database and PL/SQL.

Transfer tables between 2 clients (mandants)

Hi every one.
I want to transfer data i have in some tables from client (mandant) 305 to another another to create an environnement of test with real data so we can test new programs in real conditions.
For the moment here's what i did :
I used RFC on just one table. And this works.
BUT the problem is that to work, we need to declare the table in the parameters of the function.
So Is there any way to avoid that declaration ? Because i have like 500 tables to transfer, and i 'm sure there's a better way than mine to do that. But as i just started on SAP and ABAP, can't figure it out.
My solution for the moment will the same but with a loop on all the tables i need to trasfer the data ... but i'll have to decalare the 500 tables in the parameters of my function :s
Maybe there's another solution to communicate between mandants so if you have, ideas, documentation, links etc, it will be really helpful
thx a lot !

Hi Helder,
Let me explain you the implication whatz gonna happen if you use the following loop.
LOOP AT tab_info.
ASSIGN COMPONENT tab_info-fieldname OF STRUCTURE <wa> TO <value>.
MOVE string+tab_info-offset(tab_info-intlen) TO <value>.
ENDLOOP.
Say if I have 20 fields in my table with 2000 records, for this one table, the processor would loop for 40000 times. Which is surely pretty huge time.
Now coming to option b), it is pretty simpler. The table which I was referring is not required as we created it for a specific requirement.
List all the tables which you need for data transfer. Let us assume here as we had done and we came up with two. They are:
ZTESTA
ZTESTB
The function module has the following interface parameters:
FUNCTION zrfc_read_table.
IMPORTING
tabname TYPE dd02l-tabname
TABLES
t_ztesta
t_ztestb.
All that you do in your FM is:
FIELD-SYMBOLS: <fs_table> TYPE STANDARD TABLE.
DATA: l_inttab TYPE char64.
CONCATENATE 'T_'
            tabname
       INTO l_inttab.
ASSIGN (l_inttab) TO <fs_table>
SELECT * FROM (tabname) INTO TABLE <fs_table>.
ENDFUNCTION.
Now in your original program:
*After selecting all the tables you want(here in this case
*you would have only ZTESTA and ZTESTB in MY_TABLES)
TYPE-POOLS: abap.
DATA : table TYPE REF TO data,
        WA TYPE REF TO DATA,
        it_param TYPE STANDARD TABLE OF
                         abap_func_parmbind,
        wa_param TYPE abap_func_parmbind.
FIELD-SYMBOLS : <FS> TYPE STANDARD TABLE,
                <WA> TYPE ANY.
LOOP AT MY_TABLES.
CREATE DATA table TYPE STANDARD TABLE OF
         (MY_TABLES-TABNAME).
CREATE DATA WA TYPE (MY_TABLES-TABNAME).
ASSIGN WA->* TO <WA>.
ASSIGN TABLE->* TO <fs>
Pass the interface parameters dynamically using
it_parm which is of type abap_func_parmbind(4.7) or
abap_parmbind(4.6c) in type-pools abap.(I am not sure if
we can do it in a version less than 4.7). Let me know
in case you dont know how to pass interface parameters
to a function module dynamically.
CALL FUNCTION 'ZRFC_READ_TABLE' DESTINATION 'DO2_305'
    PARAMETER-TABLE
      it_parm.
IF sy-subrc <> 0.
     MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
     WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
LOOP AT <fs> INTO <wa>.
   INSERT (MY_TABLES-TABNAME) FROM <WA>.
ENDLOOP.
ENDLOOP.
Here you need not have to loop no. of rows * no.of columns. Also your FM is quicker as it is just one select statement and do not do anything else.
All that you need to do is to identify all the tables and add tables parameters as t_<tabname>. But the code nover change.

Srikanth

Difference between url iveiw and BSP iveiw

hi,
     What are the parameters we need for BSP iveiw and URL iveiw. What is the difference between these.

hi,
IViewLauncher
IViewLaucher can be used to launch any IView or Portal Component or a Page in the portal. Portal Component launching is supported only in NW04.
Provider specific Information
IViewLauncher is Provider agnostic. Items may belong to any connector.
Supported Actions
Action name can be anything.
Properties
IViewLauncher expects one of the following two mandatory properties:
iview - iView id or Portal Component name to be launched
page - page id of the page to be launched
All other properties will be passed as name=URL encoded value to the target iView. The dynamic properties can also be passed to an iView via the following property (since NW04 SPS18, NW04s SPS09, NY AP7):
iviewDynamicParameter - optional; name/value pairs of dynamic parameters to be passed to the iView/page. The expected format is name1=value1&name2=value2 etc.
Example
Following is the definition of an action that launches an IView with id ROLES://portal_content/com.sap.pct/every_user/general/iViews/myDemoIView.
<Action name="launchIView" handler="IViewLauncher">
<Properties>
   <Property name="iview" value="ROLES://portal_content/com.sap.pct/every_user/general/iViews/myDemoIView"/>
</Properties>
</Action>
Example on how to configure an action to launch a Portal Component com.sap.netweaver.bc.uwl.ui.DemoIView:
<Action name="launchIView" handler="IViewLauncher">
<Properties>
   <Property name="iview" value="com.sap.netweaver.bc.uwl.ui.DemoIView"/>
</Properties>
</Action>
Example on how to configure an action to launch a Portal Page with id ROLES://portal_content/com.sap.pct/every_user/general/Pages/com.sap.km.MyInfoDiscussions:
<Action name="launchIView" handler="IViewLauncher">
<Properties>
<Property name="page" value="ROLES://portal_content/com.sap.pct/every_user/general/Pages/com.sap.km.MyInfoDiscussions"/>
</Properties>
</Action>
Description
The following parameters are optionally passed on to the iView, WHEN no parameters are explicitly defined.
wi_id - work item id in the provider system
destination - system alias in the Portal system landscape of the provider system
item_id - internal UWL item id
task - provider task item type
uname - backend user id for webflow connector, alert connector and generic ABAP connector, otherwise Portal user id
langu - user language in upper case ISO language code
Additional custom defined parameters are also supported. They can be static and dynamic, i.e., substituted with an actual value during the run time.
Example of a static parameter:
<Action ...>
<Properties>
<Property name="fruit" value="apple"/>
</Properties>
</Action>
This will append &fruit=apple to the constructed url.
Dynamic property values should start with ${ . These values could come from either the Item or some common values like user.
${item.attributeName}
$ - a backend user id corresponding to the logged in Portal user if the provider system is an R3 system
attributeName is case sensitive, and must be either a custom attribute for the item, or one of the following already defined attributes:
appContext attachmentCount completedDate connectorId createdDate creatorId description dueDate escalatedBy executionUrl expiryDate externalId externalObjectId externalType forwardedBy forwardedDate internalId isEscalated itemType memoCount parentItemId priority processDueDate processor status subject subprocessId substitutedFor systemId userId (see description).
An example of using dynamic properies:
<Action ...>
<Properties>
<Property name="workitemId" value="${item.externalId}"/>
<Property name="system" value="${item.systemId}"/>
</Properties>
</Action>
This will result in passing workitemId and system parameters to the target page/iView. This is the same as specifying iviewDynamicParameter property:
<Action ...>
<Properties>
<Property name="iviewDynamicParameter" value="workitemId=${item.externalId}&system=${item.systemId}"/>
</Properties>
</Action>
Note. For webflow connector iViewLauncher can be configured on the backend using SWFVISU transaction. The table below summarizes the mapping between the launcher parameters and the visualization parameters.
Launcher parameter Visualization Type Visualization Parameter
page Portal Page ID
iview iView ID
iviewDynamicParameter iView/Portal Page DYNPARAM
UrlLauncher
UrlLauncher can be used to launch any url.
Provider specific Information
UrlLauncher is Provider agnostic. Items may belong to any connector.
Supported Actions
Action name can be anything.
Properties
UrlLauncher expects the following property:
url mandatory; url to be launched.
All other properties will be passed as name=URL encoded value to the target url.
Example
Following is the definition of an action that launches a url my.web.com and passes to it the parameter workitem_id, which is filled with the work item id during run time:
<Action name="launchUrl" handler="UrlLauncher">
<Properties>
<Property name="url" value="http://my.web.com"/>
<Property name="workitem_id" value="${item.externalId}"/>
</Properties>
</Action>

Link table between AP Invoice and AP Downpayment Invoice

Hi,
I want to get the link between the table OPCH and ODPO,
so that I can monitor the cash advances,
Thank you very much,
Regards,
Clint

Hi Gordon,
I have tried that already, if we follow the process, First we enter the Downpayment from AP Down module, after that we go to the AP Invoice and we click the button Total Down Payment to call the amount from Downpayment, we cant see the Base Entry and Target entry since both have different module but we can see they must have be a connection since Ap Invoice can call the payment from Downpayment and there must be a connection between them but I cant see how.
Thank you very much.
