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.
