Regarding Service Order distribution lock and status profile

By admin On Jan 14, 2021

I would like to share an investigation done today regarding distribution lock in Service Order.

My colleague observed that if there is no status profile maintained for Service Order transaction type,

once the service order is created and saved, you can not edit it any more. When Edit button is clicked, the error message “Document/transaction is being distributed; changes are not possible” is displayed:

However, when a status profile is maintained to the transaction type, the edit works.

Why?

In below chapter I can transaction type without status profile as scenario A and type with status profile as scenario B.

1. figure out why error message is raised in scenario A.

The message is raised in line 216 due to flag lv_status_transferring is set. However in scenario B, lv_status_transferring is initial.

2. population logic of flag lv_status_transferring

It is filled by this function module:

This function module reads order status and check whether system status I1054 “To be distributed” exists. If found, lv_status_transferring is set to true.

And I debug to find the status for scenario A:

System for scenario B:

So the next task: figure out why I1054 is created for scenario A but not for scenario B

3. status transition debug

I notice that in both scenario, the function module below will be called to set business transaction “TOR3” to order.

“TOR3” means “To be distributed”.

For scenario A, this function module is executed successfully, however in scenario B, it fails with sy-subrc = 4.

Then I debug into this function module and found it is the status profile which is assigned to transaction type prevent this status transition. The transition will NOT be performed due to the error message raised in line 448. See line 435, WHEN 3.
