Dear All
Recently for our MRP purpose, I have created some planning calendars and used them in MRP. This works as intended.
But one observation is that rescheduling dates shown in MD04 (Just after MRP run) and same shown in MD05 are different.
Previously without PC s this was not the case. Rescheduling dates just after MRP run looks same in MD04 and MD05
What can be the reason for this ?
Please let me know your thoughts on this
Regards
Shyam
Hi Shayam,
Just a thought. There can be a requirement which might have come after MRP, between the reschedule date (in mrp list) and order date.
Additionally quoting form WIKI "If the fixed element is after the requirement date, within the rescheduling horizon and this type of fixed element is included on the rescheduling check, according to the customizing, exception message “10 - Bring process forward” is displayed for the element."
so after MRP as the day progress your rescheduling horizon will also move forwards, and may get another requirement thus changing the reschedule date.
Please check your rescheduling horizon and compare the situation.
regards,
Suraj Kamble

Hello...Thanks for the feedback. I went through the note.
understood that PC is not taken into account for rescheduling.
But I have still one more question..How rescheduling date in MD04 and MD05 looks different just after MRP. Whether PC is taken into account or have any influence in MRP list (MD05) ?
Can you please clarify more?
Thanks in advance
Shyam
Hello Shyam
Yes, the MD04 and MD05 may be different just after the MRP execution.
Please refer to the following information, provided on question 3 of the
FAQ note 550441, which explains the differences on the design of both
transactions which causes this system behavior:
Question:
I can see an exception message in the MRP list (Transaction
MD05).Why does the system not display this message in the current
stock/requirements list (Transaction MD04) also?
Answer:
In Transaction MD04 you can only display exception messages that
result from the import of the MRP elements from the
database.However, the MRP list (MD05) is the result of the last
planning run, that is, the system displays such exception messages
here that occurred during the planning of this material.This also
causes exception messages from the net requirements calculation or
lot size determination.For example, exception messages '25' (Excess
stock), '70' (Max. release qty - quota exceeded) or '28' (Uncovered
reqmt after effective-out date) can only be displayed in Transaction
MD05, yet not in Transaction MD04.For more information about this,
see Note 29703.
