Hi Susan,

Picking sequences on Inventory items are stored in two different places. There is a 'default' picking sequence that is stored on the master item and is visible on the Profile tab of Item Inquiry.

You can also set a picking sequence for a specific Location for that item, and this information is visible on the Quantities tab of Item Inquiry.

The problem you are seeing with 'blank' appearing in the 'Picking sequence' when using Item Inquiry and looking at the Quantities tab is likely not a Purchase Orders issue but rather an Inventory problem. If I take an item for which 'default' pick sequences are defined for all locations, then Edit the item and on the Location tab I highlight a location and click the 'Default Seq' button, I now no longer see the Master item pick sequence in Item Inquiry, but instead it is blank.

Or if I create a new item and within Edit Item I choose to make the item Active at a location by highlighting the location and clicking the Active button, the same scenario occurs.

To fix, I had to do what you did and use Edit / Item Maintenance / Pick Sequences and reset the location to Default.

So there may be an issue somewhere in using 'Default seq' and 'Active' when creating the item and what gets written to the 'Pick Sequence by Location' data file.

Do you have the Inventory option 'Allow items at all locations' enabled? This could have an influence on what you are doing and when this information is updated. Also, how (and where) are you creating the new item and how are you making the item active at a location (when creating the item or receiving goods)?
