What causes this issue?

The system does not permit goods receipts with
<DS:GLOS.3526C31EAFAB52B9E10000009B38F974>serial numbers</> if only a
partial quantity of the item should be posted.

How to fix this error?

For serialized materials, you can only post a goods receipt for the
entire item.

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