Quantity in storage bin

Hi,

I’m a new in WM and I’m try to implement it in my client, but I’ve some doubt.

In transaction LT07 I try to create storage unit (with movement type 561), but the system give me the error message “Storage type 001 does not allow negative stock figures”. And what I see, it’s fiels “target quantity” on “from” is empty with the same error message. So, I think, but not sure if is correct, I need to upload initial stock on storage bin.

So I went to transaction LT01 with the same movement type, but fiels “target quantity” on “from” it’s still empty. So my quest is: how I will put quantity in my storage bin?

Thanks in advance.

Best regards,

Sara Silva
