Field help (NBMVTED) 

This parameter specifies the number of direct input lines impacted by the modification of the palletization program.

Definition: a direct input line is taken into account if it is not addressed and if there is at least one input movement not addressed for the same site, the same depositor, the same product, the same container or higher container depending from this container.

For example: Let us consider product A (1 PP1 = 10 CC1 = 100 CU) and a DI line of 100 CU having one entry mvt of 1 PP1 of 10 CC1 = 100 CU
If the palletization program is modified as follows: 1 PP1 = 10 CC1 becomes 1 PP1 = 8 CC1, then the mvt is impacted.
If the palletization program is modified as follows: 1 PP1 = 10 CC1 becomes1 PP1 = 15 CC1, then the mvt is impacted (in effect the palletization program is saved on the stock object but also on all the movements).
If the palletization program is modified as follows: 1 CC1 = 10 UUC becomes 1 CC1 = 5 UUC, then the mvt is impacted.
