Hi
Iam using collective process order with one subordinate order.
All Phases are having relationship. First phase 0011 has predecessor 0888
When i reschedule header order individually then schedule dates and basic dates of header order changes in increasing order with each rescheduling of header order individually. Iam using floats before and after production.
This happens while rescheduling header order individually and does not happen with subordinate order.
But when i add dummy start operation and phase without any resource then system does not change schedule dates and basic dates of header order changes in increasing order after rescheduling header order individually.
Is this standard behavior or Bug?
Please could you check in your system and let me know reason.
Hello Mayurresh,
Please refer OSS note 151503 - Consulting: Scheduling of process order
If a collective order scheduling is executed, check the following points.
1. Check which order in the collective order is scheduled.
If a collective order scheduling is executed for an order belonging to the collective order, the system schedules only the subnetwork defined by this order. Higher-level orders are not scheduled. Here, the basic dates of lower-level orders are determined by the requirements dates of the directly manufactured component.
2. Check the framework dates and the scheduling type.
During collective order scheduling, scheduling is carried out from the framework dates in the collective order while during an order scheduling the basic dates of the order are used. The system takes framework dates of lower-level orders into account (see Note 97344) provided the 'Adjust basic dates' indicator is not set to active. If thealternative 'Adjust basic dates' is chosen, the basic dates of lower-level orders are adjusted if necessary.
3. Check whether a relationship has been maintained in the directly manufactured component.
If a relationship is maintained in the detail screen of the component (here the specification of a unit of the duration is the decisive factor), the system copies the requirements date of the component to the order finish date of the lower-level order. If no relationship is maintained, the finish date of the last operation of the lower-level order is set to the requirements date. In this case, the order finish date of the lower-level order can be diffentiated from the requirements date of the component provided a float after production has been maintained in the lower-level order.
4. Check to which operation/which phase the directly-manufactured component is assigned?
Note that for a transfer of the dates of the lower-level order into higher-level order in a forwards scheduling, the directly-manufactured component must be assigned to a phase, since only phases get a lead time scheduling and as a result, only phases enable dates to be transferred. Operations get their dates from the phase dates, as described in point 2.

HI All
For further analysis, i reduce phases of operation to two with two operations.
In Second phase, i kept relationship as SS with predessor first phase.
Then issue remains same, dates keep on changing with each reschdule of header process order.
When we change relationship to FS then dates does not change with reschdule of header process order
Please could inform reason behind it

Mayuresh,
Did you try with this way Functions -> Schedule -> Collective order?

Hi Mayuresh,
Please check your Master recipe activity hours, the system calculates the scheduling dates based on it and OMDW transaction-for rescheduling horizon,tolerance value forward/for displacement.
