• What is the cause and solution for SAP error message PPEACT813 - Relationships between activities at &1 &2 are interrupted &3 times ?

  The SAP error message PPEACT813 indicates that there are interrupted relationships between activities in a project or production planning context. This typically occurs in the context of project management or production scheduling within SAP, particularly when using the Project System (PS) or Production Planning (PP) modules.
  Cause:
  The error message PPEACT813 is triggered when there are inconsistencies in the relationships (dependencies) between activities. This can happen due to several reasons, including:

  Incorrect Dates: The start or finish dates of activities may not align correctly, causing interruptions in the planned sequence.
  Changes in Activity Status: If the status of an activity changes (e.g., from "in progress" to "completed"), it may disrupt the relationships with other activities.
