MRP - Planning

Hello,

We have storage tanks for a material that can hold 20 truck loads of inventory. And we want to trigger the PR when the requirements drive the inventory below 10 truck loads to bring the inventory back to 20 truck loads. I know that there is a reorder point planning, but it is driven based on inventory levels, but in our case, we want to drive the PR creation based on the inventory levels that account for the demand.

E.g.: Material A - Inventory 20 Trucks - on Dec 19th. PDT - 2 days

Requirement 1 - Dec 20th - 5 Trucks

Requirement 2 - Dec 24th - 3 Trucks

Requirement 3 - Dec 26th - 3 Trucks (At this point the inventory would go below the 10 truck load threshold).

When we run MRP, we need system to propose a PR on Dec 27th to bring in 11 trucks to bring back the inventory to 20 truck loads.

Hopefully this is clear. can we achieve this using standard MRP Type / Lot sizing procedures?

Thank you.

    Hi Vicky,

    We need to choose MRP Type = VB ( Reorder Point Planning), Reorder Point = 10 Trucks , Lot Size as EX.

    Try this,This should serve ur requirement.

    Thanks,

    Saikrishna.

    • Hello SaiKrishna,

      We do not want to wait until the inventory actually falls bellow 10 truck loads. It will be too late for us to order. So we cant use Reorder Point planning.

    Hello

    You should choose an reorder point MRP type that considers external requirements.

    The standard MRP type V1 considers external requirements, but only within the replenishment lead time.

    You can go to the MRP type customizing and create your own MRP type, as a copy of V1, selecting the option to consider external requirements in the total horizon and selecting which types of external requirements will be considered.

    • Hi Caetano,

      external requirements have limited scope. In our case, the requirements for the material A, is part of the Production BOM for the finished product, which is not treated as a external requirement. So this approach will not work either. Thank you.

    Hi Vicky

    Dependent requirements are not considered during net requirements calculation when using a reorder point MRP type. This is standard and it cannot be changed.

    However, you can choose reservations of production orders to be considered as external requirements in customizing (transaction OMDQ).
