Manual workflow with BUS2001.Create does not deliver an entitiy

Question

Hello!
Could anyone help me with the following manual workflow please? Although I have red a lot of theory and I thought I have understood the principles of how to use the workflow builder it does not work. Could it be that I need to know more about ABAP-Programming? I would be very thankful for any tips as I need it for my diploma thesis. I work with SAP R/3 4.7 Enterprise. Here the description of the two-step workflow:
After starting the workflow manual the user has to create a project definition (with transacion CJ06). After saving (in the second step) another user will get a workitem that shows the created entity (with transaction CJ08).
First of all I have created a subtype Z_BUS2001 and have added the parameter PROJ-PSPID to the methods "ProjectDefinition.Create" and "ProjectDefinition.Display" (as import and export element).
In my workflow I have defined the following bindings:
1.     For the task “create”:
mehod container to task container:
&PROJECTDEFINITION& => &PROJECTDEFINITION&
task container to workflow container
&_WI_OBJECT_ID& => &Z_BUS2001&
&PROJECTDEFINITION& => &PROJECTDEFINITION1&
2.     For the task “display”:
Workflow container to task container
&Z_BUS2001&  => &_WI_OBJECT_ID&
&PROJECTDEFINITION1& =>&PROJECTDEFINTION&
Task container => method container
&PROJECTDEFINITION& => &PROJECTDEFINITION&
It is possible to execute the workflow. I mean the first step works, but the second step does not show the created Projectdefinition but the entrance screen. Is the binding incorrect or could it be that I have something more to do with the Z_BUS2001? Many thanks in advance for your help!

Hi Anna,
1) With the Create method of BUS2054 (WBS) you need an existing project definition (you cannot create a project with transaction CJ11). The project definition entered is stored in the user memory using the SET statement and the Display method  GETs it from the memory. This works only if the same user is executing both the tasks in the same session.
2) It is possible depending on what kind of Project Coding  Mask has been defined in your IMG. But it has to be more than the user name/id. Because once the user has created a project, another project with same name cannot be created. You will have to define your own Create method, say ZCreate, define a parameter to receive the WF initiator from the Task. In your method, get the element, generate a unique Project Def, and use the SET statement to set the parameter id PSP with your value. Similarly for the  Project def in the Template area, use parameter id VPS. Don't forget to define an element for the task to receive WF initiator, and the WF to step binding!
HTH.
