Generating Reservations
For each requisition line, if the requisitioned part is an assembly and you did not select the Stop Explosion check box for the planned order on the Component subtask of the Release Manufacturing Bills of Material in Costpoint Bills of Material, Costpoint calculates component requirements by exploding through the bill of material levels.
Requirements are based on only one level of explosion, except in the case of a phantom part for which explosion is done as an additional step. Anytime a requirement is identified, a PO reservation line is created. The warehouse corresponding to the requisition line is used to auto-assign the reservation ID.
Determining Reservation Inventory Abbreviation and Project
Costpoint uses the build-to inventory abbreviation of the assembly to check whether any inventory abbreviation peggings exist for the corresponding components. If it finds an exact match, it uses the pegged inventory abbreviation and associated project for the requirements.
If a match does not exist, there are various scenarios. If the component is a common stock part and the selected build-to project allows common inventory projects, the inventory abbreviation will be based on the one entered in the Planning subtask of the Manage Parts screen. If that is unavailable or inactive, the build-to project's common stock inventory abbreviation is used. If that is also unavailable or inactive, the Default Common Stock Inv Abbrev from the Configure Production Control Settings screen is used. In each case, the project for the requirement will be the one associated with the inventory abbreviation.
If the component is a Buy part, and the common stock part criteria cannot be met, the build-to inventory abbreviation is used to determine the default raw material inventory abbreviation and its associated project. If the component is a Make part, and the common stock part criteria cannot be met, the build-to inventory abbreviation is used to determine the default subassembly inventory abbreviation and its associated project. If none of the above conditions are met, or no inventory abbreviation codes can be found for the components, the selected build-to inventory abbreviation and associated project are used.
