how to access BO Type attribute inside workflow steps
I have created one BO Type ZBO1 which having the Key_field1, Key_field2 and Method M1 and 1 attribute Atr1 defined.
From within the Workflow Template, I have used first Activity step which uses the single step Task which in turn uses the BO Type SYSTEM method GENERICINSTANTIATE. I am passing the BO Type and Key fields Key_Field1 and Key_Field2 in input and getting the reference of the generated BO Type Object into the Workflow container Element lets say GO_1(this is of type ZBO1).This step is working fine, I can see in Workflow Technical log SWIA.
Now using this GO_1 workflow container element, in next Activity step, I have called the ZBO1 method M1.this is also working fine, I can see in Log that same Reference variable GO_1 is being used with the same key fields values. NO issue till this point.
My requirement is to set the ZBO1 attribute Atr1 inside the method M1, so that after calling the ZBO1 method M1 from workflow, I would be able to use the Atr1 using the GO_1 ( I mean I want to use Atr1 value inside the workflow using the GO_1).
in nutshell, using the GO_1(of Type ZBO1) workflow container element inside the workflow, I would be able to access all the ZBO1 attributes. (In Technical log of workflow, I should see all the attributes values gets populated for GO_1).
I have already gone through the existing Threads in this regards but not getting the idea.
please suggest me some steps to follow.
