Job Completion/Closing Maintenance - Completed Qty?

We are looking at a job in job closing and noticed the Complete Qty is 0. I didn’t know why, so checked the help but there was no help for this field… Could someone help us to understand what this field means so we can understand why it’s 0?

FYI we think we had a part setup problem where we had parts set as backflush but the operation on the material was 0…

Completed quantity comes from the operations completed on either the last operation on the job, or the operation that is checked “last operation”. Asm 0 is the top level assembly, and since you didn’t complete any on op 10 on assembly 0, you did not complete any on the job.
