MRP and Purchase Requisitions..

Question

Hello,
I want to know
             When MRP generates the Purchase Requisitions which has many due dates per lines,  how does the dating logic work. Can we state create one PO for all lines due on a specific date and create a second one for other dates.  So there for a Purchase Rec, could turn around multiple PO based on dates. We want one PO per due date, not nested due dates within the PO. It is also my understanding that this can be automated. If you automate rec to PO, can you do this per question above on PO per due date
Thanks
Kris

Please see response below:

[ANSWER] The due dates or delivery dates are completed as follows:
Delivery Date = PR Release Date + Purchasing Processing Time + Planned Delivery Time
with the following notes:
1. PR Release Data -> Time that the PR is ready for conversion to PO
2. Purchasing Processing Time -> the period it takes for the purchasing department to convert the PR's into POs; measured in work days and is maintained in Materials Management under Consumption-Based Planning u2192Plant Parameters u2192 Carry Out Overall Maintenance of Plant Parameters.
3. Planned Delivery Time - period it takes from the receipt of the PO (by the supplier) to the delivery of the goods onsite. This is measured in Calendar days and is maintained on the Material Master Record, Vendor Master Record or the Purchasing Inforecord
In addition, the Material Availability Date is computed as
Availability Date = Delivery Date + GR Processing Time
where
GR Processing Time - time it takes to process the delivery (i.e. unpacking, storage, etc) for internal use; measured in work days and is maintained in the Material Master Record
Can we state create one PO for all lines due on a specific date and create a second one for other dates. So there for a Purchase Rec, could turn around multiple PO based on dates. We want one PO per due date, not nested due dates within the PO.
[ANSWER] We can do that by using the delivery date as one of the parameters for PO creation. Although, please note that there are a lot of factors to be considered for PO creation, not just the delivery date
It is also my understanding that this can be automated. If you automate rec to PO, can you do this per question above on PO per due date
[ANSWER] Yes, this can be set in ME59N, to create a new PO per delivery date. Again, please take note of the other dependencies/requirements for creating POs as well as the other requirements for automatic generation. Note that your business processes must be healthy enough to allow the system to automatically create the Purchase Orders
Hope this helps
