How To Fix L1215 - No batch input session could be created because materials already blocked

L1215 - Overview

• Message type: E = Error

• Message class: L1 - Message handling for WM master data

• Message number: 215

• Message text: No batch input session could be created because materials already blocked

What causes this issue?

You want to generate a batch input file to clear possible stock
differences. So that the program has a consistent set of data for
Inventory Management and Warehouse Management, no postings affecting
stock levels may be executed while the program is running.

System Response

For this reason, the program has tried to block all the materials in
the respective warehouse number.
This block could not be set because in the warehouse number concerned
there are already material blocks, that is, it is most likely that
stock postings are currently taking place.

How to fix this error?

To ensure a correct comparison of stock figures, you must first make
sure that no stock postings are taking place. If you merely want to
take a look at possible stock differences, you can start the report
without the function "Generate batch input file" and thus avoid the
blocking problem.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
