infor ln item by business partner session
Also searched as
- infor ln item supplier session
- infor ln item sales business partner
- ln item purchase business partner data
Short answer
In Infor LN, item data per business partner lives in purchase and sales item sessions that tie an item to a supplier or customer with partner-specific data such as the partner's item code, prices and lead times. Find the exact session with the session search for your package.
Applies to: Infor LN 10.x. Session codes and names vary slightly by version, so confirm in your environment.
Find and use the session
- 1Use the application menu search or session search and type item plus business partner to list candidate sessions.
- 2For supply side, open the item purchase business partner session, commonly in the Purchase Control module with code starting tdipu.
- 3For demand side, open the item sales business partner session, commonly with code starting tdisa.
- 4Specify the item and business partner, then fill in the partner's item code, lead time, order unit and minimums as needed.
- 5Check the default business partner at item purchase data so ordering picks the right supplier.
- 6Save and test by creating a purchase or sales order line and confirming the partner data defaults in.
- 7Use the session's zoom or related actions to jump to price books and agreements.
What the link does
Item master data says what the item is. Item by business partner data says how a specific supplier or customer deals with it: their part number, their units, their lead time and often their price source.
Without this record, orders fall back on general defaults, and you cannot print the partner's own item code on documents.
Finding the exact session code
Session codes begin with a module prefix, for example td for Order Management and Purchase and Sales sub areas. The in-app session search is the most reliable way to confirm names and codes in your release.
Because naming differs between versions and customizations, verify the code before documenting it internally.
Data quality
Duplicated or missing partner records cause wrong defaults. Run periodic checks for items with no supplier, or active suppliers with no valid price.

Conversion Factor Session in Infor LN: Setup and Common Errors
Infor LN converts between units using conversion factors, either general factors between units of the same physical dimension or item-specific factors that override them. When an item is bought in one unit and stocked in another, LN needs a factor for that pair. A missing factor is the usual cause of a conversion error on purchase orders, receipts or sales lines.
How-toPrice Book Session in Infor LN: Setup and Order Pricing
In Infor LN, a price book holds the selling prices for items, and LN selects the price for a sales order line by looking up the applicable price book through its pricing setup. If a sales line shows no price or the wrong one, check price book validity dates, the item and unit, the customer's assigned price structure and currency. Session names vary by version, so search the session list for price book.
How-toHow to calculate item cost prices in Infor LN
Infor LN calculates an item's cost price by rolling up material, labor, machine, subcontract and overhead costs defined against cost components, using the item's bill of material and routing as the calculation base for manufactured items and purchase price for bought items. The calculation can run in simulation mode to preview the result or in update mode to actually change the item's standard cost, which then drives inventory valuation and variance reporting going forward.
Error fixInfor LN bshell Process Stuck at 100% CPU: How to Diagnose and Fix It
A bshell process pinned at 100% CPU on the Infor LN application server almost always means one session is stuck in a 4GL loop, scanning an unindexed table, or waiting on a database lock. End the session from the Sessions Monitor first, then kill the OS process only if that fails, and check for a blocking database transaction before assuming it is a bug.
Error fixInfor LN Not Authorized to Run This Session: How to Fix It
Infor LN refuses to open a session with a not authorized message when the logged-in user's assigned role does not include that session, or when the session is blocked for the company they are logged into. Grant the session through Common > Authorization Management > Roles, or check the user's role and company context, and the session opens on retry. In most cases this is a permissions configuration issue, not a bug.
Error fixInfor LN DAL Out of Sync After a Custom Field: Cause and Fix
Infor LN throws a DAL, or table, out of sync error, or simply drops a new custom field silently, when a table's dictionary definition is changed but the generated DAL and dependent forms are not regenerated afterward. Running the standard sequence, table compile, DAL generation, then session/form compile, in Tools > Development after every dictionary change resolves it. Skipping any one of the three steps is what causes the mismatch.
