When the start date of an MRO interim order header, or some disassembly or disposition order within that structure, has changed, you can propagate the effects of that change through all the start and supply dates for the disassembly and disposition orders downstream (i.e., to all the disassembly and disposition orders after this point) in the order structure. The start and supply dates are calculated using the lead times specified for the parts.
Note: propagating dates downstream only impacts disassembly and disposition orders below the point of propagation. Repair and assembly orders are unaffected.
You can inititate the command Propagate Dates Downstream from the header or from a specific disassembly or disposition order in the structure. When initiated from the interim order header, dates will be calculated starting with the top-level disassembly order and ending with the lowest-level disassembly or disposition order. You can only propagate the dates from the interim order header if the interim orders have not yet been been released (i.e., while the header is in state Created). However, even after the interim orders have been released, the same result can be accomplished by propagating downstream from the top disassembly order.
On the other hand, if this activity is initiated from a specific disassembly or disposition interim order in the structure, the dates are calculated starting from that level and below in the interim order structure.
The interim order header or interim order from which dates are being propagated cannot be in a Canceled or Closed state.
The start and supply dates for all disassembly and disposition orders below the point of propagation are re-calculated from the new start date based on the part lead times.
