SAP EWM: Error with assigning fixed storage bins to products

Hello,

I want to customize fixed bins strategy.

And the last step is to assign fixed storage bins to product with t-code /SCWM/FBINASN.

And i receive the following error:

0 fixed bins have been assigned to products (failed: 2)

Message no. /SCWM/PUT_BIN_DET108

Could you please advise how to fix this error ?
