There is a need for a situation which appeared several times, to manage time change in the master planning.
The idea is to set a reservation on a resource when a production order follow an another production order, between them.
It could be a good idea to use the sequencing.
Each released product could be attached with a sequence and these sequences could be ranked by priority.
Timing could be set on a matrix to know how long the time between 2 production orders should be, depending on which sequences are following each others.
This time change will be planned in advance by the MRP, but has to be automatically updated in case any change in the production scheduling.
