Diagnosis
To carry out the operation, the type and the length of the element &V1&are required. However, the reference field used in the containerdefinition is not (actively) available in the ABAP Dictionary of thecurrent system. It was also not possible to determine a type of theelement or expression '&V4&' on the right side of the assignment.

System Response
The workflow was suspended and set to error status.

Procedure
You should ensure that in the case of an assignment "Result:=element/expression", either the result element or at least the elementor expression on the right side has a type definition.
If this is the case, you should check the reference structure in theABAP Dictionary. If the workflow is from another system, it may be thatthe reference structure was not copied or transported or activated atthe same time.
