Specifying it is not necessary in the following cases:
- the issue is multi-lot,
- not all the characteristics of the stock to be issued are specified (lot, sub-lot, serial number, location).
If the product is managed with serial numbers, only this number is necessary to determine the stock to issue.
If not, the lot, sub-lot and location (conditioned by the product management method) are needed.
For credit memos, if the product is not managed by lot, this field cannot be accessed. If the product is managed in mandatory or optional lot, the field availability depends on:
- the settings of the Credit memo entry transaction used,
- The lot management rule linked to the Delivery return movement defined in the product Category or in the stock management rules. At this level, it is possible to specify the type of lot entry and to assign a default value to the lot.
At the end of the entry, if no lot number has been entered, several cases can arise:
- the movement management rule allocates the document number,
- the system uses the lot sequence number for the product to allocate a new lot number. If no sequence number for the lot has been specified for the product and the lot is mandatory, a blocking message is displayed.
