Field help (LOTSRH) 

If the product is managed by lot, different cases are possible based on the lot management rule associated with the Shipment return transaction type and based on the product lot management rule.
SEEINFOIf a product is not managed by lot, the Lot and Supplier Lot columns cannot be accessed.

If a product is managed with mandatory or optional lots, the access to the lot field depends on one hand on the setup of the return transaction used and on the other hand on the management rule Delivery return defined in the product category or in the stock management rules.

At the level, you can indeed specify whether the lot is not to be entered, free of entry, or if only new lots can be entered.

In addition, it will be possible to allocate a default value to a lot. In this case, several choices are also offered. Never initialize the lot or initialize the lot with a document number (the initialization with the document number is not visible during the entry if the return number is automatically allocated at the creation, it is given a blank value).
If you do not enter the lot number in the lot field, the document number is written in the lot field upon posting the note. The choice of initializing the internal lot with the supplier lot is not active in a delivery return context.

When the entry is completed, if no lot number has been entered, several cases can arise:

Specific case of the products managed as optional lot

This product type allows the entry of a blank lot field. In this case, this must be indicated by entering the lot field and clicking Blank lot from the Actions menu. Then, when saving the document, the sequence numbers or the document number will not be used. This management method is thus incompatible with a management rule that does not allow the entry of an internal lot number.

The grid given below summarizes the impact of the setup of the management rule for the movement type Shipment return with mandatory lot management during the entry of a direct return.
For optional lots, click Blank lot from the Actions icon to indicate that you are recording a blank (empty) lot.
