SAP Error Message - Details

• Message class: UCS0 - Messages for Status Management

• Message text: Cycle in technical preceding task relationships for task &1-

What causes this issue?

Technical preceding task relationships between the relevant tasks result
from the Customizing settings of <LS>reclassification</> and <LS>
allocation</> methods.
Example: Task A uses method M and task B uses method N. The target
assignment of method M also occurs in the trigger for method N. As a
result, task A is a technical predecessor of task B.
The function <LS>Check Preceding Task Relationships</> determines the
preceding task relationships for <LS>reclassification</> and <LS>
allocation</> tasks and executes a consistency check.
The system has detected a cycle in the technical preceding task
relationships of task &V1&. This means that task &V1& indirectly acts as
its own predecessor.
A cycle in the technical preceding task relationships can lead to
unwanted postings in reclassification or allocation.

How to fix this error?

tasks and methods and adjust them if necessary to ensure that cycles no
longer exist in the technical preceding task relationships.
