The SAP error message /SAPAPO/PE173 Not all triggers in selection are active typically occurs in the context of SAP Advanced Planning and Optimization (APO) when you are trying to execute a planning run, such as a heuristic or optimization run, and not all the triggers (or planning objects) that you have selected are active. This can happen for various reasons, including configuration issues or data inconsistencies. Cause Inactive Triggers: The most common cause is that some of the planning objects (like products, locations, or resources) in your selection do not have active planning triggers. This means that they are not set up to be included in the planning run. Data Inconsistencies: There may be inconsistencies in the master data or planning data that prevent certain triggers from being activated. Selection Criteria: The selection criteria used for the planning run may include objects that are not relevant or not set up correctly in the system. Solution Check
