How To Fix 61208 - Short and long-term lot-size indicator not compatible

SAP Error Message - Details

• Message type: E = Error

• Message class: 61 - Fehlermeldungen fuer Bedarfsplanung

• Message number: 208

• Message text: Short and long-term lot-size indicator not compatible

What causes this issue?

The lot-sizing procedure for the short-term period and the long-term
period are not compatible.

System Response

The lot size in the short-term period should always be more "exact"
than the lot size in the long-term period, that is, the lot size chosen
for the short-term period should provide small lots that cover the
requirements more precisely. For this reason different combinations are
not allowed:
the lot-for-lot order quantity in the long-term period requires the
lot-for-lot order quantity in the short-term period
period lot sizes are only compatible if the period indicator of the
short-term lot size is smaller or equal to the long-term lot size. For
example, you can have a monthly lot size in the long-term period along
with a weekly lot size in the short-term period.
a daily lot size in the long-term period is not possible with an
optimum lot size in the short-term period.

  The SAP error message 61208, which states "Short and long-term lot-size indicator not compatible," typically occurs in the context of material requirements planning (MRP) and inventory management. This error indicates that there is a mismatch between the short-term and long-term lot size settings for a material in the system.
  Cause:
  
  Lot Size Configuration: The error usually arises when the lot size settings for a material are not compatible. For example, if the short-term lot size is set to a specific value that does not align with the long-term lot size settings, the system will trigger this error.
  Material Master Data: The material master data may have inconsistent settings for lot sizes, leading to this incompatibility.
  MRP Type: The MRP type assigned to the material may not support the combination of short-term and long-term lot sizes being used.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03) and check the lot size settings under the MRP view.
  Ensure that the short-term and long-term lot size indicators are compatible. You may need to adjust one of them to resolve the conflict.

  Review MRP Type:
  
  Check the MRP type assigned to the material. If the MRP type does not support the desired lot size settings, consider changing it to a more appropriate type.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to lot size settings and MRP configuration for further guidance.
  
  
  
  Testing:
