SAP Note 12518 - Field name does not exist in batch input data

Symptom:

The following error message occurs during run-time of batch input:
00346 Field name does not exist in batch input data.

Cause and prerequisites

1. You tried to provide a field name in a screen with data using batch
input, and the field does not exist
The error message appears as follows:
00346 Field name HUGO does not exist in batch input data.
Field name HUGO does not exist in screen.


2. You tried to provide a field name in a screen with data using
batch input, and the field's name is "Space" and/or has "Space"
as field value.
The error message appears as follows:
00346 Field name does not exist in batch input data.
Field name is space.

Solution
1. Correct the BDCDATA table by using a valid field name in the
screen.

2. Important: field name SPACE
Use transaction SM35, function Session (F8) to analyze the
session that was created, position the cursor on the screen
where the error occurred, and press Data (F16).

If the list of field names and values contains empty lines - that is
field name and/or value are SPACE - you must change the report that
creates the batch input sessions.
