• What is the cause and solution for SAP error message /SCMTMS/TAL026 - Allocation overbooked ?

  The SAP error message /SCMTMS/TAL026 Allocation overbooked typically occurs in the context of SAP Transportation Management (TM) when there is an attempt to allocate more resources (like vehicles or containers) than are available for a specific transportation task. This can happen during the planning or execution phases when the system checks the availability of resources against the planned transportation requirements.
  Cause:
  
  Resource Overbooking: The most common cause is that the total quantity of goods to be transported exceeds the available capacity of the allocated resources.
  Incorrect Master Data: There may be discrepancies in the master data, such as incorrect capacity settings for vehicles or containers.
  Planning Errors: Errors in the planning process, such as not considering the actual available capacity or not updating the system with the latest resource availability.
  Multiple Orders: If multiple transportation orders are trying to use the same resource simultaneously, it can lead to overbooking.
  
  Solution:
  
  Check Resource Availability: Verify the available capacity of the resources (vehicles, containers, etc.) in the system. Ensure that the capacity settings are correct and reflect the actual available resources.
  Adjust Transportation Requirements: If possible, reduce the quantity of goods to be transported or split the transportation into multiple trips to fit within the available capacity.
  Update Master Data: Ensure that the master data for the resources is accurate. This includes checking the capacity settings for vehicles and containers in the system.
  Replan Transportation: If the allocation is still overbooked, consider replanning the transportation to allocate resources more effectively.
  Check for Conflicting Orders: Investigate if there are other transportation orders that are conflicting with the current allocation and adjust accordingly.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like /SCMTMS/PLN for planning or /SCMTMS/ALC for allocation to check the details of the transportation orders and resources.
