SAP Note 12389 - Batch input customer: Data for Screen nnnn missing

Symptom:

Batch input for customers issues the error message:
'Batch input data for Screen nnnn does not exist'

Cause and prerequisites

Error in batch input handling: Data interface is supplied with
input for fields which are not ready for input.

Solution
Analyse the incorrect session with SM35. Check in SD Customizing
whether all relevant fields are ready for input. As a rule, the
screen fields affected are those which are processed directly BEFORE
the screen specifed in the error message.
You should check whether the customer can be created in dialog
with exactly the same data as in the batch input interface.
