  The SAP error message /SAPAPO/OM149 indicates that there is an issue with the scheduling direction of activities in the Advanced Planning and Optimization (APO) module. This error typically arises when the system cannot determine the correct scheduling direction for a set of activities, which can occur due to various reasons.
