Bin to Bin stock Transfer using LT10

Hi all,

I am getting an error message: 'Storage bin BUFFER KIT is currently being processed by ' (error code L3 145) when trying to move stock:

FROM: storage type 210 (buffer kit)

TO: storage type 210 (01-017-01)

I have read the SAP note 373297 and went through the causes and prerequisities:

"The symptoms described above occur if the destination bin location is assigned as fixed and is not created via a dynamic coordinate."

I have checked the movement type 999:

a) The destination bin location (BUFFER KIT) is NOT assigned as fixed.

b) The destination bin location has not been created via a dynamic coordinate. There is no interim storage bin included in this transfer.

please see movement type 999 configuration attached.

None of the help i read has helped me.

Any thoughts?

Thanks a lot,

Marco Santos
