UCS0402 - Task &1: Technical predecessor &2 is not an explicit predecessor

SAP Error Message - Details

• Message type: E = Error

• Message class: UCS0 - Messages for Status Management

• Message number: 402

• Message text: Task &1: Technical predecessor &2 is not an explicit predecessor

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
technical preceding task relationships for <LS>reclassification</> and
<LS>allocation</> tasks and checks the technical preceding task
relationships for consistency against the settings for the explicit
preceding task relationships that you specified in the process view of
the consolidation workbench under the "Consolidation Monitor ->
Preceding Task Relationships" node.
The system has determined that task &V2& is a technical predecessor of
task &V1&. However, you have <ZH>not</> specified that task &V2& is an
explicit predecessor of task &V1&.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check the settings for the preceding task relationships and, if
necessary, add task &V2& to the definition of the preceding tasks for
task &V1&.
