Cost Code Level Mismatch Between Project L5 and Area L4 Blocks Auto-Creation

Product - Unifier, version - 24.12.1

We have project shells set up with a Cost Sheet at WBS Level 5 using code structure 01.XXX.XXX.XXX.XXX.

Our Area shells are set up at WBS Level 4 with Cost Sheet code structure 01.XXX.XXX.XXX.

We’re using auto-creation to generate Area shell records from the project level, but it’s failing to pick the codes. The records aren’t progressing because the L5 cost codes from the project don’t map to the L4 structure in the Area shell.

Question:
How can we resolve this mapping issue so that L5 project records correctly auto-create/roll up into the L4 Area shell,
