No batch input data for dynpro & &

What causes this issue?

The transaction sent a screen that was not expected in the batch input
session and which therefore could not be supplied with data.
Possible reasons:
1. The batch input session was created incorrectly. The sequence of
screens was recordly incorrectly.
2. The transaction behaves differently in background processing in a
batch work process than when running in dialog (SY-BATCH is queried and
changes the screen sequence).
3. The transaction has undergone user-specific Customizing and
therefore certain screens may be skipped or processed differently,
according to the current user. If the person who created a batch input
session is not the same as the person now processing it, this problem
may occur frequently.

System Response

None.

How to fix this error?

For 1: Either re-create the session or process it in expert mode.
Correct the batch input program.
For 2. It is very difficult to analyze this problem, particularly in
the case that the screen sequence or the display-only options of fields
differ according to whether the transaction is being processed in the
background or as an online dialog. It could also be that this kind of
transaction cannot run with batch input.
For 3: Have the creator of the session process it. If no error occurs
now, then this is a program with user-specific Customizing.
