Storage bin available when posting change is not confirmed completely

Dear Gurus, I have a question for you:

My costumer wants to do a posting change when the material is released from QM with a decision usage from Q to unrestricted use. The process is done in two steps: with LU04 the TO is generated and with LT12 is confirmed. When the TO is generated the position is half confirmed. With LT21 we can see the row for the ST (lets say ST 504 Open Storage type) and a second row 922 TR-ZONE. The first row appears green (as confirmed) and the second row appears red (Not confirmed).

My costumer says that " beacause of the strategy given for the storage entry, the storage bin released in the TO (not confirmed completely yet) is available at this moment.

If the storage bin is still physically full, the carrier will found not space for leaving the goods even SAP is telling him there is space available at this storage bin."

I have read that once yo start a TO the storage bin is blocked until the transaction is fully confirmed.

If this is correct I need to demostrate it and I don not find the way to do it.

I hope you understand my explanation and give me any clue.

I appreciate very much some help.

    A storage bin is not locked due to an open transfer order for material in the bin. The actual qty (quant) will be locked for transfer order creation if that qty is already on an Open t.o. You can have multiple open transfer orders against the same quant.

    This does depend on you storage types setting though...

    It sounds like you auto confirm set for your posting change notice transfer orders but the second part of the t.o. is failing to confirm emediatly? Perhaps fixing the issue that is preventing the transer order from completing would correct you issue so you would not have any open t.o. as you mentioned. and you would not need to use lt12 to confirm the second part, I assume the system forces you to do that?

      I was in bed thinking over the problem, and suddenly I've got the solution! .

      The problem is the setting of the bin. The material has to move from one storage bin to another different. I set the flag in the config of movement "post to same bin" OFF and eureka!. it works.

      Thank you very much for your help.
