is it true that in WM to use dynamic interim storage (POs) it is not necessary to execute trx LX20 and if I want to use fixed interim storage I need to create storage bins?
I'm asking this 'cause system in LX20 shows the following:
The following storage bins have not been created yet:
WWhse Stor.typ Stor.bin
Z03 901 WE-ZONE
Z03 902 WE-ZONE
Z03 910 WA-ZONE
Z03 917 QUALITY
Z03 920 TRANSFER
Z03 921 TRANSFER
Z03 922 TR-ZONE
Z03 922 U-ZONE
Z03 923 PACK.BIN
Z03 980 DUMMY
Z03 998 AUFNAHME
Z03 999 LOST&FOUND
Z03 999 SCHROTT
........these seems are fixed interim storage bins
If you really would have only dynamic bins, then you would not need to execute LX20.
The bins you see are fixed bins, thats right (and they have the wonderful German names)
SAP can create a quant with a dynamic bin number if the quant is created from a goods receipt to a PO. But what dynamic bin should SAP create if you do a GR without PO reference?
In this case you need the fixed bins.
You should rename them, in the IMG for define WM movement types, that they become more understandable for the warehouse folks (except you are working in Germany)
