You use the lot-sizing procedure to determine how the system is to calculate the reorder quantity in the planning run.

A lot size defining the lot-sizing procedure is assigned to every material master record applicable to materials planning.

The lot size is defined in Customizing by the combination of the lot-sizing procedure and the lot-sizing indicator.

Three procedures for lot sizing are available:

  • static lot-sizing procedures
  • period lot-sizing procedures
  • optimizing lot-sizing procedures

You use the lot-size indicator to define the procedure.

The following parameters are also available for controlling the lot-sizing procedure:

  • Short-term and long-term lot size

    You can split the lot-sizing procedure into a short-term and a long-term period. This means that you can select one lot-sizing procedure in the near future and a different one in the distant future.

    You define the periods in the section of the screen entitled "End of the short-term period/start of the long-term period".

    The valid from date of the long-term lot size area is defined via:

    • a periodicity
    • a number of periods

      The beginning of the long-term period is calculated by taking todays' date and adding the number of periods in the future; the long-term planning period then starts on the next complete period.

      Note

      For materials that are planned using the short and long-term lot size, it is recommended that you define a maximum MRP period. Defining the MRP period has the effect that materials after a certain period are included in planning even if no changes relevant to the planning run have occurred. This avoids a situation where order proposals created with the long-term lot size move into the short-term period because no changes relevant to MRP have occurred for the material.
      You define the maximum MRP period in the step, "Define maximum MRP period". A material that is planned on a regular basis should also be provided with an MRP type that contains the indicator for regular MRP.

  • Scheduling indicator

    For period lot sizes, you can use the indicator for scheduling to determine whether the availability date;

  • is to be set to the first requirements date in the period
  • or is to be set to the beginning of the period
  • is to be set to the end of the period
  • or whether the period start represents the beginning of the planned order and the period end represents the availability date (repetitive manufacturing)
  • Interpretation of the delivery times

    For the lot-sizing procedure, you can also define whether the period start is to be interpreted as the delivery date or as the availability date using the indicator, "interpretation of the calendar times".

    NOTE

    The indicators, Scheduling and Interpr.deliv.times are mutually exclusive.

  • Indicator for the splitting quota

    For the quota arrangements, you can determine whether the requirements quantities are to be distributed to several items, that is, whether they are to be split. With the splitting quota arrangement, requirement quantities are not simply allocated to the smallest quota rating. Instead, they are distributed among various sources using the following formula:
    Quantity for source of supply X = Quota of source X * reqmts quantity
    ------------------------------------
    Sum of all quotas

  • Overlapping indicator

    The overlapping indicator along with the cycle time in the material master record are used to split the planned orders into several partial quantities whereby the in-house production time overlaps by the cycle time.

  • Lot-sizing procedure for make-to-order production

    In make-to-order production, you can use the indicator, Lot size for make-to-order production to determine whether,

  • the order quantity is to be calculated using the exact lot size
  • the order quantity is to be calculated using the exact lot size and the system is also to take the rounding quantity or the minimum and maximum lot size into account
  • the order quantity is to be calculated using the lot-sizing procedure defined for the short-term area
  • Maximum stock level variant

    The system only displays the Maximum stock level variant field in the lot-sizing procedure, Replenishing to maximum stock level. The indicator only has an effect in connection with reorder point planning taking external requirements into account and in connection with material requirements planning and controls how the system calculates lot sizes.

Standard settings

In the SAP standard system, the lot-sizing procedures are preset.

Recommendation

SAP recommends that you use the lot-sizing procedures in the standard system.

Actions

  • If necessary, adjust the number of periods for the period lot size to the SAP standard delivery.
  • If you are using reorder point planning taking external requirements into account, check how the system is to calculate lot sizes using the lot-sizing procedure, Replenish to maximum stock level, and enter the appropriate indicator in the Maximum stock level variant field.
  • If necessary, define new lot-sizing procedures.
  • If necessary, maintain further parameters.
