Hi,

Please refer the test plan below.

Create a serial structure with multiple  levels. Issue recreated in 22R1 Core Regional Test CMB environment. The customer flow reported and the business process related to the issue is also attached.

Create two task cards.set active

Report fault for a subassembly having a leaf part at a lower level .

Insert the task cards via manage fault information

Verify if the data are visible in the maintenance events per serial structure.

Create a new maintenance order.

Assign the maintenance events

Release the maintenance order.

Go to work order structure navigator.

Prepare work order and release the work tasks

Copy work task ID 16415

Check manage serial structure

We will be processing this part(the leaf part under 11000-1-1) next with serial NO-1009

Execute work task 16415

Assume we are returning the  leaf part (11000-1-1-01)

Perform the structure change and verify via manage serial structure

Return part to inventory

Create CRO via heavy maintenance returns

Make sure to enter the installation work task number as 16416(the second work task) Assuming that it will be used for installation

Work task no 16416 is the installation work task no which the destination for using during the assembly

Verify whether the respective work task exists

Approve CRO and release to repair.

Process the Disposition shop order Use this disposition code which Does not reuse the part

Release and Approve the DSO

Check the work task. The quantity is reserved

The serial is reserved for the next work task even though the disposition code is set as do not re-use.

Please check and advise if this is the expected system behavior
