Setting ISB Unit Quantity
The ISB Unit Quantity field of Service Item Maintenance affects how non-serial-controlled items are added to the installed base on an item-by-item basis. This field does not affect serialized items, which are always added with a quantity of one.
• When the field is No and you ship a quantity greater than one on a sales order line, the system creates only one ISB record for the shipment quantity. If you ship three items, the system creates one ISB record for a quantity of three.
• When the field is Yes, the system creates unique ISB reference numbers for each item shipped and each record has a quantity of one. The shipment line with a quantity of three creates three records for the same item number (and lot) but with three reference numbers.
Recording Call Activity for Multiple Items
ISB Unit Quantity affects how items in the installed base can be repaired in Call Activity Recording. If the quantity of the item to be repaired does not match the ISB record, components issued and returned in CAR do not update the installed base.
If ISB Unit Quantity is Yes and you always create a call line for each item to be repaired, you will not encounter quantity mismatches in CAR. Otherwise, change the quantity on the line item to match the installed base record if you want components to update the installed base.
