SAPLink plugin for Workflow objects

Recently I found myself as a SAPLink user- a client of mine was not offering a remote access and at the same time they were expecting some pilot solution ASAP. So I had to do developments in a comercially accessible IDES system and then tranport it to the client’s. And as Workflow was involved I had to trasnport not only conventional ABAP code but also a number of Workflow objects. Unfortunately I did not find a plugin for Workflow objects and so I had to develop one.

Those who need it feel free to download attached XML file which is actually a NUGGET containing 4 classes for export/import Workflow objects: Standard Tasks (object PDTS), Agent determination rules (object PDAC), and Workflow templates (object PDWS).

This all is just out of the oven, so let’s say it’s in “alpha”.

Tested on NW 7.02.

      Hello Katrice,

      Seems you have an old version of ZSAPLINK class. In the varsion I have there is a TRY... CATCH block around plugin instanciation statement in GETPLUGINS method:

      TRY.

               CREATE OBJECT classobject

                 TYPE

                   (clsname)

                 EXPORTING

                   name      = 'foo'.

               objtype = classobject->getobjecttype( ).

             CATCH cx_root.

               CONTINUE.

           ENDTRY.

      Either download more recent version or fix it yourself.

      HTH.

      Katrice,

      I can see Workflow objects in the search help on slinkee tab. It is likely they are at the bottom: PDWS, PDAC, PDTS.

      Dear Sergey,

      great to see SAPlink getting support for Workflow. It would be great if you can join the SAPlink plug-in's project and host your code there. This would allow to include the code in the SAPlink plugins package.

      Best regards

      Gregor

      Hi Sergey,


      Thanks for your valuable contributions.

      I have query regarding the number range while replicating the Wflow objects in the target system.

      In general, all workflow objects produce unique numbers during creation.

      Would these classes able to assign new number range for to be created Wflow objects using SAPLink.

      Please clarify.


      Regards,

      Ravi

      Hi Amruth,

      What errors do you have?

      An exception occurred that is explained in detail below.

      Error :


      CREATE OBJECT on abstract class not possible.

      Error Analysis :


      The exception, which is assigned to class 'CX_SY_CREATE_OBJECT_ERROR', was not

        caught in procedure "GETPLUGINS" "(METHOD)", nor was it propagated by a RAISING clause.

      Since the caller of the procedure could not have anticipated that the exception would occur, the current program is terminated. The reason for the exception is: The dynamically specified class "ZSAPLINK_WF" at CREATE OBJECT is 'abstract'.

      You cannot create instances from abstract classes. Note: A class is 'abstract' if it was defined with the addition  'ABSTRACT', for example, because one or several methods are not

      implemented, and are to be implemented in a subclass.

      Hi Amruth,

      Actually it should be enough to activate 4 classes:
      ZSAPLINK_WF

      ZSAPLINK_WF_ACTOR_RULE

      ZSAPLINK_WF_STASK

      ZSAPLINK_WF_TEMPLATE

      After that ZSAPLINK report should recognize object type PDWS, PDTS, and PDAC.

      I´m activated all 4 classes, and  PDWS, PDTS and PDAC objects don´t show in search help.

      Hello Wallace,

      Unfortunately I don't have 7.31 at hand and thus I am afraid cannot help with the issue.
      When creating the list of available objects ZSAPLINK tries to create an instance of each plugin class inside TRY...CATCH cx_root block. Apparently there is something incompatible with 7.31 in the code. If you have time you can check this by testing one of classes (e.g. ZSAPLINK_WF_STASK) in SE24 separately. It should report some error when creating instance.

      Hi Sergey,

      My Master co-work made some workaround changes in zsaplink class GETPLUGINS method, like that code bellow :

           tabletypeline-object = objtype.

           APPEND tabletypeline TO tabletypesin.

           IF classline-clsname = 'ZSAPLINK_WF'.

             FREE tabletypesin.

             tabletypeline-object = 'PDAC'.

             APPEND tabletypeline TO tabletypesin.

             tabletypeline-object = 'PDTG'.

             APPEND tabletypeline TO tabletypesin.

             tabletypeline-object = 'PDTS'.

             APPEND tabletypeline TO tabletypesin.

             tabletypeline-object = 'PDWA'.

             APPEND tabletypeline TO tabletypesin.

             tabletypeline-object = 'PDWS'.

             APPEND tabletypeline TO tabletypesin.

           ENDIF.

           CALL FUNCTION 'TRINT_OBJECT_TABLE'

             TABLES

               tt_types_in  = tabletypesin

               tt_types_out = tabletypesout.

      Thanks Wallace! In this case, the return of the GET_OTYPE method of the ZSAPLINK_WF class should be one table category (array). However this change reflected in the other classes (plugins). But, the GETPLUGINS method of the ZSAPLINK class must be prepared. I changed quickly for solved my problem. But is not  better solution, ok?

      Vinicius, it´s a workaround solution. It´ will fixed in future by saplink team, I hope 🙂

      Append de code below in zsaplink method GETPLUGINS:

      -----------------------------------------------

      SELECT * FROM vseoextend APPENDING TABLE classlist

             WHERE refclsname = 'ZSAPLINK_WF'

             AND version = '1'.

      -------------------------------

      Now the program see the class:

      ZSAPLINK_WF_ACTOR_RULE

      ZSAPLINK_WF_STASK

      ZSAPLINK_WF_TEMPLATE

      and show PDWS, PDTS and PDAC objects in search help.

      Author's profile photo Former Member
      Former Member

      Or even better:

      Instead of appending the above code in the GETPLUGINS method of class ZSAPLINK, simply modify the "SELECT * FROM VSEOEXTEND ..." command at the very beginning of the same method and replace:

      refclsname = 'ZSAPLINK'

      in WHERE clause by:

      refclsname LIKE 'ZSAPLINK%'

      Then, the only restriction would be that all SAPLINK plugin classes would have to be a descendant of classes whose names begin with ZSAPLINK.

      This is exactly the case with ZSAPLINK_WH, This class, which descends from ZSAPLINK, is the superclass of all three workflow-related plugin classes.

      Hi All,

      Since workflows and BORs often work together, I have developed a SAPLINK plugin to deal with BOR objects.

      I couldn't find a way to upload it here, so anyone who wants it, just drop me a line and I'll email it to you: lino@hr.com.br

      Cheers!

      Hi Lino,

      It's great to see that for BOR objects SAPLink plugin is available. Please send it to my mail id sunrays08@gmail.com.

      I request you to make this plugin available on the SDN or any web portal for everyone.

      Appreciate your efforts.

      Thanks,
