/SAPAPO/RRP_CDOC056 - Details

• The SAP error message /SAPAPO/RRP_CDOC056 indicates that the operation start date for a production order or a planned order has been adjusted to the start of the planning horizon. This typically occurs in the context of Advanced Planning and Optimization (APO) within SAP, particularly when dealing with production planning and scheduling.
  
  Cause:
  
  Planning Horizon Settings: The planning horizon in SAP APO defines the time frame within which planning activities are performed. If the operation's start date falls outside this horizon, the system automatically adjusts it to the beginning of the planning horizon.
  Order Dates: The dates associated with the production or planned order may have been set incorrectly, leading to a situation where the start date is not feasible within the defined planning horizon.
  Capacity Constraints: If there are capacity constraints or resource availability issues, the system may adjust the start date to ensure that the operation can be scheduled within the available capacity.
