How system determines One-Step STO and the movement type for the delivery afterwards?
When you create an STO, do you know it is one-step or two-steps transport? When you
create delivery for the STO, can you judge if the movement type system determined is correct or
In this blog, let me introduce my way to check these points.
★Whether the STO is considered as 1-step?
As you can see in the picture above, system check table T161W with supplying plant+ recieving plant +
document category. The document type of the STO is not a key for determination at all. You can check
table T161W to see if this STO is considered as one-step or not.
★How system determines the movement type?
Afterwards, system checked the delivery item category, in T-code VL03N you can see it,
for example the delivery item category is NLRN. Then in the following customizing:
Sales and Distribution ->
Sales -> Sales documents ->
Schedule lines -> Assign schedule line categories
system founds the schedule line category, for example it is NR. At last, in T-code VOV6, for Sched.line cat NR,
you can see there is setting:
Movement Type 671
Movement Type 1-Step 677
Therefore if the STO is one-step transport, then the movement type will be 677 in the delivery. Otherwise it will

Also this blog starts somewhere in the middle of nowhere. I had to use Google to lookup the movement types 671 and 673 to know that your blog is about returns, this is not mentioned in a single word in your blog.
How can the end users without debugging and IMG access know that it is one-step or two-step return?
I corrected the points you mentioned, thanks for the reminder.
For the end users, they don't need to debug or check IMG setting, these are only for
analysis, in case they want to verify how system works and if the result is correct.
They can simply check table T161W with supplying plant+ recieving plant +
document category for STO, and for the delivery, they can see the movement type in
HI Yang Bai,
First I would like to thank you for sharing these informations, I would like to ask you in case of one step procedure, How system determines the movement type for the Good receipts 101 ? since I want to create a custom mvt Z01 and in case of one step procedure for STO I want the good receipt to determine Z01 instead of 101.
Waiting for your kind reply,
