Delivaery Date in MRP PR

[Former Member]

Hi All,

How the delivery date is calculated in MRP generated?

Here is the scenario:

We have planned del time in material master is 14 days, GR processing time is 2 days.

PR has created on 23 Nov 2011, and it gave the delevery date 28.12.2011 how?

FYI: There is a contract where the planned delivery time is 28 days, and also there is a reservation for same material for 261 movment and the requirement date is 11.01.2012.

Could you please help to understand this calculation.

Thanks in advance.

Hi,

There are three components in calculating planned delivery time, read below.

Planned Delivery Time= +Purchasing processing time + Planned delivery time + GR processing time.+

Purchasing processing time = Time taken by purchasing to Convert PR into PO Calculated based on working days (as per factory calendar)

Planned delivery time = The planned delivery time is the number of days required to procure the material from external procurement. (Calculated based on calendar days)

GR processing time: The goods receipt processing time is the timeframe between receiving the material and the receipt in the warehouse. It is required for unpacking, checking, storing material and so on. (Calculated based on working days)(as per factory calendar).

Hope this answers your question.

A contract and reservation is no way related to each other in this context.

A contract is long term agreement from vendor to buy something at an agreed price and condition.

Reservation: Reserving Depenedent goods. (Ex. BOM Components are reserved when a planned order is converted into a Production order.)

The role of MRP: it plans, the procurement cycle when certain materials falls below (re-order point VB(one of many ways)) because a reservation was created and subsequently the stock fell below re-order point.

If the contract was maked as MRP relevant in source list then, MRP can create PR against the contract in MRP.
