<ZH>without</> relationships, in other words, all the operations will
be considered as sequential and scheduled accordingly.

• What is the cause and solution for SAP error message IW752 - Scheduling will be changed to reflect exclusion of relationships ?

  The SAP error message IW752, which states "Scheduling will be changed to reflect exclusion of relationships," typically occurs in the context of maintenance planning and scheduling within the SAP system, particularly when dealing with maintenance orders or work orders.
  Cause:
  This error message is generally triggered when there are conflicting relationships or dependencies between tasks or operations in a maintenance order. Specifically, it can occur when:
  
  Incompatible Relationships: The scheduling of operations is affected by the exclusion of certain relationships (like finish-to-start, start-to-start, etc.) that are not compatible with the current scheduling logic.
  Resource Constraints: If resources (like labor or equipment) are not available for certain operations, the system may exclude those relationships to adjust the schedule.

  Solution:
  To resolve the IW752 error, you can take the following steps:
  
  Review Relationships: Check the relationships between operations in the maintenance order. Ensure that they are correctly defined and compatible with the scheduling logic.
