No goods receipt processing time for order for product &1, loc &2

What causes this issue?

A goods receipt processing time and/or goods issue processing time is
defined in the Product Master for the procured product. This cannot be
taken into account as a handling resource is required for this purpose.
The handling resource does not exist or has not been assigned to the
model.

System Response

The order does not contain any goods receipt processing time/goods
issue processing time.

How to fix this error?

Define a handling resource in the location. Ensure that you assign the
resource to the model. Alternatively, you can set the goods receipt
processing time and goods issue processing time in the Product Master
to zero.
