What causes this issue?

You wish to create a release order against a contract.
The contract item, which was created without a material number,
contains the <DS:GLOS.3526C0C9AFAB52B9E10000009B38F974>order unit</>
&V2&. In the release order, you have entered a material that has the
<DS:GLOS.3526BF21AFAB52B9E10000009B38F974>base unit of measure</> &V1&.
The base unit &V1& of the material cannot be converted into the order
unit &V2& of the contract item. The entry is therefore not allowed.

Check the contract entered or maintain conversion factors in the
material master record where necessary.

• What is the cause and solution for SAP error message 06739 - Base unit &1 and order unit &2 incompatible ?

  The SAP error message "06739 Base unit &1 and order unit &2 incompatible" typically occurs when there is a mismatch between the base unit of measure and the order unit of measure for a material in a purchasing or inventory management context. This can happen in various scenarios, such as when creating purchase orders, production orders, or inventory transactions.
  Cause:
  
  Unit of Measure Configuration: The base unit of measure (UoM) defined for the material does not match the order unit of measure being used in the transaction. For example, if the base unit is set to "pieces" and the order unit is set to "boxes," and the conversion factor is not defined or is incorrect, this error can occur.
  Material Master Data: The material master data may not be correctly configured. The base unit of measure and the order unit of measure must be compatible.
  Conversion Factors: If there are no conversion factors defined between the base unit and the order unit, or if the conversion factors are incorrect, this can lead to the error.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03).
  Check the "Basic Data" view to verify the base unit of measure.
  Check the "Purchasing" view to verify the order unit of measure.
  Ensure that the base unit and order unit are compatible.
  
  
  
  Define Conversion Factors:
  
  If the base unit and order unit are different, ensure that the conversion factors are defined correctly in the material master.
  You can do this in the "Purchasing" view of the material master by specifying the conversion factor between the base unit and the order unit.
  
  
  
  Adjust Purchase Order or Transaction:
  
  If you are creating a purchase order or another transaction, ensure that you are using the correct unit of measure that matches the material's configuration.
  If necessary, change the order unit in the transaction to match the base unit or vice versa.
  
  
  
  Consult Documentation:
  
  If you are unsure about the correct units of measure or how to configure them, refer to SAP documentation or consult with your SAP functional consultant.
