Hi,

i have defined the lot size EX in MM01 and the minimum lotsize quantity is 100...but while creating purchase order for the same material less than the minimumlotsize quantity (i.e) for 50 it is accepting to do. So what is the use of defining the lotsize quantity.....

thanks in advance.

Hi

Minimum lot size is used only when the PR's are created using MRP, If you maintain the lots size in the Material master it does not mean , that the sytem will stop you.

In thematerial master you are specifying the Planning parameters for planning through MRP.

Thanks & Regards

Hi,

Before MD02, you should have Planned Independent requirement maintained in MD61 for header material or same.

Hi,

Check in OPPQ - Plant Parameters for MRP are maintained?

Also check MD20 - Planning file entry and update it

Definition: lot-sizing procedure

Material Requirements Planning (PP-MRP)

A procedure in material requirements planning used to calculate order and production quantities (lot sizes).

Lot-sizing procedures are divided into the following groups:

Static

Period

Optimum

Production Planning and Detailed Scheduling (SCM-APO-PPS)

Procedure in production planning that is used to calculate the purchase order quantities of receipts.

In the SAP APO (Advanced Planner and Optimizer), the following standard lot-sizing procedures are available, which can be configured in the location product master.

Exact lot size

Fixed lot size

Period lot size

Reorder point procedure

For further lot-sizing procedures there are special heuristics available, e.g.

Groff lot-sizing procedure

Reorder point planning

Fixed lot size

Quantity that will be ordered or produced in the event of a shortage.

Procedure

If the amount of the shortage is less than the fixed lot size, it is the fixed lot size that is ordered or produced (and not the lesser quantity that is actually required).

If the amount of the shortage is greater than the fixed lot size, a multiple of the fixed lot size is procured. The system creates several purchase order proposals for this purpose.

Hi,

This Lot Size will not control the quantity at the time of manual creation of PR and PO.

It will control the MRP calculation. During MRP Run, it will generate Planned Order and Purchase Requisitions as per this lot size.

Check once in MD02 by running MRP.
