Error when writing IDoc status: No status record exists

What causes this issue?

The status record of the IDoc could not be written in the previous
step because the function module for application input has not returned
any status record. This error can only result from a program error.

How to fix this error?

If the error was caused by a standard function module for application
input, please contact SAP.
Otherwise check the function module that was called.
