When maintaining the material master record, you can specify additional requirements for lot size calculation. These include lot size rounding and minimum and maximum lot sizes.
You can use lot size rounding to adjust the procurement quantities to the restrictions of the delivery, packaging, and transport units. This can be useful, for example, if the ordered quantities can only be delivered in boxes containing a certain number of pieces, or if the quantities can only be packed and transported in full pallets.
During the planning run, to determine the procurement quantity, the system first calculates the net requirements, then applies the specified lot-sizing procedure and finally rounds up the quantity, if rounding instructions have been maintained in the material master record.
The following options are available for maintaining rounding data in the material master record:
Rounding Value: If you have maintained a rounding value, the system rounds the calculated quantity to the multiple of this value.
Rounding Profile:
Using a rounding profile allows for scaled rounding.
Rounding profiles must be configured individually. SAP does not deliver default settings. Once your configuration expert has created and configured a rounding profile, you can assign it in a material master record.
A rounding profile consists of threshold values and rounding values. The threshold is the value at which the system rounds up. The rounding value is the value to which the system rounds up when the threshold is exceeded.
If the requirement value exceeds the first threshold, the system rounds up to the next multiple of the rounding value found.
If the requirement value falls below the first threshold, the system uses the original requirement value.
Example of a Rounding Profile
Consider the following scenario: A material is managed in pieces; it should be delivered in layers (1 layer equals 5 pieces) or in pallets (1 pallet equals 8 layers equals 40 pieces). You have created the following rounding profile in Customizing:
| Threshold Value | Rounding Value |
|---|
| 2 | 5 |
| 32 | 40 |
Let's look at some examples of the order quantities that would result from using such a profile:
| Calculated order quantity before rounding | Order quantity after rounding | Explanation |
|---|
| 1 | 1 | The requirement value is less than the first threshold (2). That's why the system does not round up. |
| 2 | 5 | The first threshold is reached. The system rounds up to 5. |
| 6 | 10 | 5 is included in 6. For the remaining 1 piece, the system rounds up to 5. This results in a procurement quantity of 10 pieces. |
| 7 | 10 | 5 is included in 7. For the remaining 2 pieces, the system rounds up to 5. This results in a procurement quantity of 10 pieces. |
| 21 | 25 | 5 is included 4 times in 21. For the remaining 1 piece, the system rounds up to 5. This results in an order quantity of 25. |
| 31 | 35 | 5 is included 6 times in 31. For the remaining 1 piece, the system rounds up to 5. This results in an order quantity of 35. |
| 32 | 40 | The second threshold is reached. The system rounds up to 40. |
| 41 | 45 | 40 is included once in 41. For the remaining 1 piece, the system rounds up to 5. This results in an order quantity of 45 pieces. |
| 74 | 80 | 40 is included once in 80. For the remaining 34 pieces, the system rounds up to 40. This results in an order quantity of 80 pieces. |
