• What is the cause and solution for SAP error message PPEACT606 - Objects &1 and &2 are indirectly linked on a lower level ?

  The SAP error message PPEACT606 indicates that there is an issue with the relationships between objects in a project or planning scenario, specifically that two objects are indirectly linked through a lower-level object. This typically occurs in the context of SAP's Project System (PS) or Production Planning (PP) modules, where dependencies between tasks, activities, or components are defined.
  Cause:
  The error arises when you attempt to perform an action (like scheduling, releasing, or planning) on two objects that are not directly linked but are connected through another object. This can happen in scenarios such as:

  Identify the Objects: Review the error message to identify the two objects (&1 and &2) mentioned in the error. You will need to understand their relationships.

  Changing the dependencies or links between the objects.
  Deleting or modifying the lower-level object that is causing the indirect link.
