In WM, you can divide a storage type into storage sections and activate storage section checks in Customizing. Previously, for stock placements, the system searched for storage sections that were allowed for each material and all manually entered storage sections were also checked.
Beginning with Release 4.0, this "solid connection" between searching and checking is no longer necessary. You can now work with storage section search without system checks when you make manual entries.
The field Storage section check active in Customizing for storage types has been changed to allow checks and searches as before (indicator x) and includes the option for section search without section checks (indicator y).
