SAP Note 12490 - EM during processing: fields not filled

Symptom:

When you process a BTCI session for transaction PA61, an error
message is issued: no input for screen MP200000 2450.
The session was created by a customer-written report.

Cause and prerequisites

In contrast to master data, module pool MP200000 is always used for
batch input for time data. Therefore the module pool name cannot
be derived from the number of the infotype.

Solution
Use the right screens.
How do I find the right screens?
- Run through a sample transaction on the screen.
- After each screen change, use
-> System -> Status to see which screen you are looking at.
You must then use these screens in your report.

Key word: Batch input
