====1.3.5. Catch Weight====

{{ :implementation:wms2:configuration:item_master:catch_weight_tab.png |Catch Weight tab}}

**//Catch weight item?//** \\
Indicates if the item is a catch weight item.

**//GS1 AI for uom//** \\
The GS1 application identifier to capture the quantity for pieces.
Possible values:
  * 37 (Count)
  * 31 (Net weight Kilo)
  * 32 (Net weight Pound)

**//GS1 AI for uom2//** \\
The GS1 application identifier to capture the quantity for the weight. 
Possible values:
  * 37 (Count)
  * 31 (Net weight Kilo)
  * 32 (Net weight Pound)

**//1 uom = xxx uom 2//** \\
The weight of 1 piece.

**//Weight tolerance (%)//** \\
The weight tolerance in percentage. Here it can be defined what the allowed tolerance for the weight is. If the tolerance >= 100, no tolerance check will be done. This check will be used for all documents except: goods issue and goods receipts.
Calculation:   \\
( Pieces * Default weight of 1 piece ) -  \\
( Pieces * Default weight of 1 piece ) * Weight tolerance/100 \\
< **Allowed weight** < \\
( Pieces * Default weight of 1 piece ) + \\
( Pieces * Default weight of 1 piece ) * Weight tolerance/100 \\


**//Uom to use for purchase//** \\
The uom that should be asked when receiving items. \\
Possible values: \\
  * Pieces (UOM1): The weight is calculated based on the weight of 1 piece. \\
  * Weight (UOM2): The number of pieces are calculated based on the weight of 1 piece. \\
  * Pieces and weight \\

**//Uom to use for inventory//** \\
The uom that should be asked when moving items. \\
Possible values: \\
  * Pieces (UOM1): The weight is calculated based on the weight of 1 piece. \\
  * Weight (UOM2): The number of pieces are calculated based on the weight of 1 piece. \\
  * Pieces and weight \\

**//Uom to use for sales//**
The uom that should be asked when delivering items. \\
Possible values: \\
  * Pieces (UOM1): The weight is calculated based on the weight of 1 piece. \\
  * Weight (UOM2): The number of pieces are calculated based on the weight of 1 piece. \\
  * Pieces and weight \\

**//Price calculation for sales//** \\
The calculation of the price for creating a sales delivery. \\
Possible values: \\
  * Price by piece: This option is the default option. In this case no price calculation is done because the price from SAP is already by piece \\
  * Price by weight: The calculation of the price is done by weight. \\

**Price by weight** \\
When a sales delivery/reserve invoice is generated, the price will need to be set when: \\
  * The item is a catch weight item \\
  * The option for price calculation is set to 'Price by weight' \\
  * The base document is NOT an invoice \\
  * Delivery is made through Produmex functionality \\

The unit price before discount will be adjusted. The default unit price is based on the default weight of a catch weight item. So a recalculation based on the actual delivered weight needs to be done.

The calculation formula is: Unit price before discount = (Unit price before discount sales order / Default weight by piece) * Actual weight) / Quantity

Database columns: DLN1.PriceBefDi = ( RDR1.PriceBefDi / OITM.U_PMX_DQUM) * DLN1.U_PMX_QTY2 ) + DLN1.Quantity

**Example:** \\

ItemA \\
* Inventory uom = Case \\
* Weight uom = Pounds \\
* 1 Case = 24 pounds (U_PMX_DQUM = 24) \\
* Price per case = 48$ (= 2$ / pound) \\

Sales order \\
* 20 cases \\
* Unit price = 48$ \\
* Total price = 960$ \\

When we deliver the 20 cases the actual weight = 500 pound (Nominal weight was 480 pound) \\
The calculation is as follows:

(Unit price sales order / Default weight by piece) * Actual weight) / Quantity = Unit price

(48$/24 pounds) * 500 pounds) / 20 cases = 50$ \\

Total price of the delivery line will be 1000$ \\
This means if you deliver 500 pounds, this is 2$ by pound.

**//Scan weight for each case//** \\
When this is enabled, when scanning/entering the weight in the device, the system will not automatically calculate the number of pieces that would be associated with the weight, but it will use the # pieces in a case.\\
So on the first entry of the weight, the user can either enter the total weight for all pieces.\\
Flow:
  * Check if scanned weight is within tolerance of the # pieces in case
  * Yes: Use the pieces and weight, and ask for next weight
  * No:
    * Check if the scanned weight is within tolerance of the needed number of pieces
    * Yes: Use the needed number of pieces, and total weight
    * No: Error is shown that weight is not within tolerance


**//# pieces in case//** \\
This is used in combination with the setting 'Scan weight for each case'.
It stored the number of pieces in a case.

**//Record weight details during picking//** \\
When this is enabled, the entered weight during picking on a device will be stored in a separate table: PMX_WDET.\\
It stores the pick list doc entry, item and batch details.\\
This allows to retrieve the detailed weight entry for an item on a pick list.
