• Message type: E = Error

• Message class: CO - PPC order processing messages

• Message number: 777

• Message text: Routing &: Base unit of measure & and order unit & are incompatible

What causes this issue?

The operation unit of measure in the routing or in the production order
cannot be converted to the order unit of measure from the purchasing
info record. This can have the following causes:
The units have a different dimension
The units have the same dimension but an overflow has occurred when
determining the conversion.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Proceed as follows depending on the causes:
RESET N1
Adjust the dimension of the units in the routing or in the production
order or in the purchasing info record.
If possible, change the conversion by shortening the ratios as much as
possible.

• What is the cause and solution for SAP error message CO777 - Routing &: Base unit of measure & and order unit & are incompatible ?

  The SAP error message CO777 indicates that there is an incompatibility between the base unit of measure and the order unit in a routing. This typically occurs when the units of measure defined for a material in the routing do not match or are not compatible with the units of measure defined in the material master.
  Cause:
  
  Incompatible Units of Measure: The base unit of measure (the unit in which the material is primarily managed) and the order unit (the unit in which the production order is processed) are not compatible. For example, if the base unit is in kilograms and the order unit is in grams, this can lead to incompatibility.
  Routing Configuration: The routing may have been set up incorrectly, with units of measure that do not align with the material master data.
  Material Master Settings: The material master may have incorrect or inconsistent unit of measure settings.
  
  Solution:
  
  
  Check Material Master:
  
  Go to the material master (transaction code MM03) and check the units of measure defined for the material.
  Ensure that the base unit of measure and the order unit are compatible.
  
  
  
  Review Routing:
  
  Access the routing (transaction code CA03) and check the units of measure used in the operations.
  Ensure that the units of measure in the routing match those in the material master.
  
  
  
  Adjust Units of Measure:
  
  If there is a mismatch, you may need to adjust either the material master or the routing to ensure compatibility.
  You can change the order unit in the routing or adjust the base unit of measure in the material master as needed.
  
  
  
  Recreate Routing: If the routing is complex or has many operations, it may be easier to recreate the routing with the correct units of measure.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on unit of measure settings and routing configurations.
  
  
  Related Information:
  
  Unit of Measure Configuration: Understanding how units of measure are configured in SAP is crucial. This includes knowing how to set up base units, alternative units, and order units.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to this error message.
  Testing: After making changes, test the routing and production order to ensure that the error does not reoccur.
  
  By following these steps, you should be able to resolve the CO777 error and ensure that your routing and material master data are correctly aligned.
