OK for those confused.

1. The captain writes up, APU INOP.
2. Captain (if it is flight crew placard able) flight crew placards it as MEL whatever, MOC control number. When the plane came into a MX base, MX would come out and place a permanent MEL in the MX side of the MX log book the MX corrective action block.

3. Now the Captain regarding the item will be required to flight crew placard and do the MX corrective action and be responsible that all previous MEL's are appropriate (which is what MX used to do) and MX will not come to see the MX issue until the MEL runs out.

Terminology may be different from one airline to the next. Every company I worked for the left side of the MX Log Book was filled in by Captain and MX but only MX will fill out the right side of the MX Log Book. Now we are doing MX administrative work which has additional legalities via the FAR's.

But never fear, the ALPA MEC is hard at work giving the store away.
