Transportation unit is not currently at a checkpoint

Hi ,

The scenario is,  we have 50 yard bins in a perticular YARD. As of now only have a single checkpoint.  So We cannot activate of deactivate any TU other than main YARD BIN.  Getting error

Transportation unit A**********/ is not currently at a checkpoint

Option I have is, Create all the Yard BIn as Checkpount and then map each Yard Bin to corresponding check point via  /SCWM/YM_CHKPT_BIN .

But, then user needs to to change 'Default Values"  - Chekcpoint before  every Transaction .

Is there any easy way to fix this? Means can we manage this scenario with Single Chekcpoint ?
