Why aren't items showing on Acumatica's Create Purchase Orders screen?

Items are usually missing from Create Purchase Orders (PO505000) for one of four reasons. They were never processed on Prepare Replenishment, their replenishment source sends them to transfers instead, a filter on the screen hides them, or Acumatica calculated nothing to order. Check them in that order and you will find most gaps in a few minutes.

Did the item go through Prepare Replenishment first?

Create Purchase Orders only shows replenishment lines that have already been processed on Prepare Replenishment (IN508000). Processing creates a replenishment request, and only that request appears on the purchasing screen.

If the item never showed on Prepare Replenishment either, the problem is upstream. Acumatica's help says the form only displays items whose planning method is Inventory Replenishment. It lists an item at a warehouse only when Item Warehouse Details (IN204500) has a Reorder Point and Replenishment Source set to Purchase. Also check these settings:

• The Inventory Replenishment feature, plus Multiple Warehouse Locations or Multiple Warehouses, is enabled on Enable/Disable Features (CS100000).
• The item's row on the Inventory Planning tab of Stock Items (IN202500) has a Method other than None.
• The warehouse's default Replenishment Class on Warehouses (IN204000) matches the class on the item's row. Stock item settings are copied to Item Warehouse Details for the warehouse with the same replenishment class.
• You did not change the item class after creating the item and expect the change to flow down. Acumatica does not copy later item class changes to existing stock items.

Our guide to setting reorder points in Acumatica walks through that setup.

Is the request going to transfers instead of purchases?

A processed request lands on Create Transfer Orders (SO509000), not Create Purchase Orders, when its source is Transfer or when a purchase is routed through a distribution center.

On Prepare Replenishment, look at the Replenishment Source and Source Warehouse columns. To buy straight into the demand warehouse, the source must be Purchase and Source Warehouse must be blank. If a distribution center warehouse is filled in, Acumatica treats the line as consolidated purchasing and creates a transfer request for the demand warehouse.

Is a filter on Create Purchase Orders hiding the line?

The Selection area on Create Purchase Orders filters aggressively, and a leftover value hides lines without warning. Clear each of these and look again:

Why is Qty. to Process empty or zero?

Acumatica suggests a purchase only when available stock has reached or fallen below the reorder point. Even then, the quantity is what is needed to get back to Max. Qty. after counting supply and demand. If supply already covers the gap, the answer is zero, and nothing is worth processing.

Common causes:

• Open or prepared POs count as supply. Qty. on Supply includes purchase orders, purchase receipts, in-transit and inventory receipts. It also includes Qty. PO Prepared, which covers orders still On Hold or Pending Approval.
• Max. Qty. equals Reorder Point. When you apply calculated parameters on Apply Replenishment Parameters (IN509500), Acumatica sets Max. Qty. equal to the reorder point. That leaves almost no room between the two, so raise Max. Qty. on Item Warehouse Details.
• Demand is not what you expect. Qty. on Demand follows the item class Demand Calculation setting. Hard Demand Only counts allocated, shipped and back-ordered sales lines, not every open order.
• Only Suggested Items is ticked. On Prepare Replenishment this check box hides items that do not need replenishment.

What about the vendor and units?

Check that the item has a default vendor on the Vendors tab of Stock Items, or a Preferred Vendor on Item Warehouse Details. The request goes to that vendor.

Remember that the purchase unit can make a line look different. Prepare Replenishment works in the base unit, and Create Purchase Orders converts to the purchase unit. A request for ten eaches can show as one box.

How can you see why each item was or wasn't suggested?

Acumatica shows the inputs column by column but does not write out the reasoning. ReorderOwl, a purchasing agent you use in ChatGPT, takes a different approach. It reads sales history, stock on hand, open purchase orders, vendors and lead times from Acumatica, forecasts each item, and returns an Excel workbook that explains every line, including the forecast method used. Items with no lead time are flagged in the workbook so you can fix them at the source.

The Acumatica connection is built and tested against Acumatica test systems, and we connect it to yours with you during setup. Read more on ReorderOwl for Acumatica.

Frequently asked questions

I processed items on Prepare Replenishment. Why are they not on Create Purchase Orders?

Check the Replenishment Source and Source Warehouse on the processed rows. Transfer-sourced requests, and purchases routed through a distribution center, go to Create Transfer Orders. If the source is Purchase, clear the Requested On, product manager and workgroup filters on Create Purchase Orders.

Why does an item with low stock not appear on Prepare Replenishment?

The item needs Inventory Replenishment as its planning method, a replenishment method other than None, and a Reorder Point with Purchase as the source on Item Warehouse Details for that warehouse.

Do purchase orders on hold reduce the suggested quantity?

Yes. Prepare Replenishment counts Qty. PO Prepared, which covers orders On Hold or Pending Approval, in Qty. on Supply, so they reduce Qty. to Process.

Why did my Max. Qty. change after applying calculated parameters?

Applying calculated parameters on Apply Replenishment Parameters sets Max. Qty. equal to the reorder point. Adjust it by hand on Item Warehouse Details if you want larger orders.
