Consider Dynamic pegging in Strategy parameters for dependent objects

[Former Member]

Dear All,

I have specified "Consider Dynamic pegging within the propagation range" in the DS strategy profile for strategy parameters of Dependent objects"

However still when i Do a drag and drop functionality on the detailed scheduling board, system allows me to schedule the operations as and when required without the respecting the pegging.

As per the documentation on help.sap.com , I expect system to move the dependent objects ( dymanically pegged receipts ) as soon as the requirement element is moved on the dashboard so that the dynamic pegging relationship is maintained.

However system is not doing so - it allows me to move the parent requirement anywhere and breaks the dymanic pegging with the dependent receipt.

Has anyone worked with such a scenario earlier.

Thanks for the help!!

Thanks

Ameet

Hi Ameet.

As per F1 help on "Consider Dynamic Pegging" option in the Strategy Profile, Dynamic Pegging is not considered when the availability date of the receipt is later than the requirement's date of the pegged requirement. Also, in order for Dynamic Pegging to be considered, it is necessary to consider Fixed Pegging and Order-Internal Relationships as well, did you already check that? Another thing you can check is in the General Strategy Settings of the Strategy Profile what has been defined in the "Actions in case of Scheduling Error" option, if you defined that the system can break pegging relationships when there is a scheduling error (if that is the case, there should be a warning message in the scheduling logs saying that the system had to break a pegging relationship to schedule the operation).

Regards,

Tiago

Hi Tiago,

Thanks for your reply. However I have maintained the said settings in the strategy profile. Also I am not getting any scheduling error for the system to break the pegging relations. Instead I am getting the message "Rescheduling Successful" but with broken pegged relations.

My requirement is that the end time of one order should always exactly correspond to the start time of the subsequent order.

I planned to achieve it by making "Maximum Earliness of the Receipt" as 00:01 in the product master - Pegging tab.

Hence I expected the system to preserve the dynamic pegging between 2 pegged orders as and when any of the two orders is moved on the Detail scheduling board. This seemed to be possible theoretically based on the documentation on help.sap.com. However it is not working as expected - may be I am missing something.

Please let me know if there is any other better way to achieve this functionality.

Thanks

Hi,

Post rescheduling you can try running bottom up heuristics.

Hi Santosh,

Thanks ! Bottoms-Up heuristc works to some extent. However it schedules the activities infinitely on the resource,. Hence I am planning to use Reschedule heuristic subsequently with "Find Slot" mode.

However I am still surpised that although system uses the "Consider Dynamic Pegging" only to find the dependent orders and maintains the the time relationship bethween them i.e. Dependent Operation should not be scheduled after the main operation. But it does not try to maintain the Dynamic pegging relationship in case the dependent order is too early than the allowable pegging intervals.

Thanks

Hi Amit,

I donot think it behaves as you explained but not sure about it.

As post rescheduling it forms dynamic pegging again.

I would like know what setteing is made for action in case of scheduling error is it terminate immediately?

Meanwhile let me try out and get back.

Santosh
