The best way is to have the approved alternate item appear on the Bill of Material just after the standard item with a zero required quantity. Now the alternate item will appear on the Shop Order. So, if the standard item is not available, the alternate item can be issued to the shop order.

When the shop order is closed out, one item will have an unfavorable variance while the other shows a favorable variance. This is an easy way to provide alternate items provided engineering approves and they are part of the Bill of Material.

When to use a user defined inventory transaction

ERP LX (BPCS) provides you with the flexibility to create inventory transactions without program modifications. The typical transaction types are defined with effects set on how the transaction will impact inventory balances.

Perhaps you want to process a customer return and don’t want to the inventory to be impacted. You can create a user define transaction effect to allow the customer receipt and not update the inventory balance.

OPERATIONS: Update, Cancel or Remove Outbound Order Lines

FINANCE: Currency Differences Accounts

TECHNOLOGY: Advantages of Data Replication

Instead of sharing tables through logical linking, you can replicate table content between companies. This approach allows certain non-key attributes of a record to vary by company. For example, if you replicate bills of materials rather than sharing them, each company can associate a different warehouse with the same bill of material. This way, the bills of materials are consistent across companies, while the warehouses can differ.

Replication also enables selective availability of records in other companies. For instance, when replicating items, you might limit which items are available in a sales company based on their item group, only including end items. You can further refine replication to specific subsets, such as particular item groups.

Keep in mind that replication requires any referenced tables to be either replicated or shared as well.
