Translate the EBS item master and its organization assignments into D365 shared products and released products, decide which item Descriptive Flexfields earn a target home, and get units of measure and categories right before anything downstream depends on them.
Product data is the quiet workstream. It rarely produces the arguments that flexfield decomposition or operating-unit design produce, and it is therefore easy to schedule late and staff thinly.
In EBS, an item is defined in a master organisation and then assigned to the inventory organisations that use it. Attribute controls determine which item attributes are master-level and which may vary by organisation, so an item can legitimately behave differently in two organisations.
Item records accumulate Descriptive Flexfields more than any other object, because adding a segment is the path of least resistance whenever a business needs one more attribute.
Units of measure sit in the shared reference foundation of the load plan, alongside currencies, exchange rate types and fiscal calendars. That placement is a dependency statement: nothing product-shaped can load until units exist.
EBS category sets do several jobs simultaneously. A single item can belong to a purchasing category set, a planning category set, an inventory category set and one or more reporting sets, and different modules read different sets.
Three areas need client discovery and should be recorded as open rather than assumed:
Product data sits in the fourth wave of the load plan, with costing. Three downstream designs cannot close until it does:
The item master to shared product mapping is direct, and the organisation-assignment to released-product mapping is not — because the axis changes from inventory organisation to legal entity, and the answer comes from the organisational crosswalk rather than from the item data.
