Note 1272921 Details:

When does this problem occur

A task is based on a class method (for example, CL_SWF_FORMABSENC CREATE). The taks is the first step in a workflow. You start the w
orkflow for the first time using SWUS. It runs without errors. You then start the workflow a second time, without leaving SWUS, and the workflow receives the status ERROR.

WL821 Work item ... Object... Method ...cannot be executed
W8899: Call of method...of class....failed:
Incorrect type for parameter

Description of problem

Cause of the problem and Pre-requisites

The result parameter of the method has an object-value. When the result is transferred to the task container, the method MERGE is called. For the delta handling, the value for the object-value element is requested. The element is then initialized. However, it is located in the def-extension of the task container.

The def-extension is reused during the next workflow start. The content has changed, which causes the error.

The problem occurs only for object-type elements.

Solution instructions

You must execute the delta handling on a copy. This is already implemented for all other elements. Only for object-type elements, a copy is not yet used. This error is corrected with the correction.

Implement the correction instructions.
