Hi Laksmi,
Even if you completed all the settings related to putaway into bulk storage type, I recommend to check the following points.
1. First of all check the message log - /SCWM/TODLV_I - Go-to - Message log. You might get where is the actual issue.
2. Then you can check if the sort sequence is created for new generated storage bins.
3. Also check if the correct HU type and storage bin type combination is maintained in configuration.
4. Check what is putaway rule is maintained for search sequence, warehouse number and WPT combination in configuration.
I think, hopefully these check will solve your issues.
Thanks,
Sandip
