Overview:

Create multiple items after matching on Holdings. Additional "multiples" requirement that is needed

Steps to Reproduce:

2. Copy holding hrid a to 901$a fields at the attached file

3. Match Holding by hrid and create Item

Expected Results: 2 Items created

Actual Results: 1 Item created
