Field help (SLOSMR) 

If the product is managed by lot and sub-lot, specify, during a receipt, the sub-lot number associated to the internal lot. This entry is optional at the level of the note line since it can be necessary to distribute a lot over several sub-lots.
By default, the system proposes the sub-lot number 00001 if no sub-lot number has yet been assigned to a lot in the entry. If this is not the case, the next sub-lot number is suggested as an increment of the last sub-lot.
It is possible in certain cases for the system not to offer the next sub-lot because the last sub-lot corresponds to a character chain that cannot be incremented (e.g. "AAAAA").
There is still the possibility however to enter a sub-lot code that does not correspond to the suggested sub-lot. Potentially, it is possible to enter a sub-lot that is already allocated to the lot.

You can enter the number of sub-lots at the level of the receipt note line. If a number greater than one is entered, the system automatically calculates the sub-lots to be allocated using the sub-lot code entered (in this case the stock detail window will automatically open in order to validate the distribution calculated by the system).
The Ending sub-lot number is displayed.
If the '$' character is present in the two Sub-lot columns, this means the sub-lots entered in the stock detail are not consecutive. In the detail line, it is possible to define as many sub-lots as there are stock units.

If a single sub-lot is required, the Ending sub-lot end number is identical to the Starting sub-lot number.
On the Sub-lot field, click New from the Actions menu to calculate the next Sub-lot number based on the last known Sub-lot.
