Oracle Retail Allocations (13.2) - Partial Data populated on the 'Search for Items' block

Hello,

We have recently installed Oracle Retail Allocation 13.2. We already have functioning 13.2 RMS. However, when I login to Allocations, I see only some field LOVs populated in the "Search for item' block. For example, Warehouse, Supplier etc. are populated with relevant data. However, they do not fetch any item or department information. Both of these LOVs are blank.

I confirmed that relevant items exist in RMS (fashion items with item_aggregate_ind = Y at the style level, and relevant WH ranged with positive stock on hand).

Is there any setup that we are missing?

Really appreciate your help on this.
