Total Replenishement Lead Time (MRP3--availability check)

mrp3--> Availability Check---> Total replenishment leads time (in workdays)

For in-house produced material and it is taken to consideration in the availability check. In a availability check where the system takes the replenishment lead time to consideration, it only checks whether the Re is sufficient incoming quantities and stocks available to cover the requirements within the replenishment leads time. Outside The replenishment leads Time,the system assumes that the material are available in sufficient quantity.



If for the material which are procured by external procurement, procurement type:f

Requested PO delivery date + GR processing time (mpr2-->scheduling) = = > PO requirement/receipt date (MD04)

PO Document Date + planned delivery time (mpr2-->scheduling) = = > Realistic delivery date

Total replenishment leads time (in workdays)

The total replenishment leads time is the time needed before the product is completely available again BOM levels have been procured or produced. It is not a calculated by the system, but defined in this field as the total of the in-house production time (s) and /or the planned delivery time (s) of the longest production path.

This was necessary if, for materials produced in-house, the replenishment leads time is to being taken into consideration In the availability check.

In a availability check where the system takes the replenishment lead time to consideration, it only checks whether the Re is sufficient incoming quantities and stocks available to cover the requirements within the replenishment leads time. Outside The replenishment leads Time,the system assumes that the material are available in sufficient quantity.

Therefore, in this situation, it's usually necessary to depict the product's total replenishment leads time with all BOM l Evels as the replenishment lead time.

Use

The following options exist for materials produced in-house if the replenishment leads time is included in the availability Check

• The total replenishment leads Time field is maintained.

in this case, the time maintained in this field is used for the availability check.

• The total replenishment leads Time field is not maintained.

the system reads the in-house production time and, if available, the Goods receipt processing time, an D interprets the total of these and the replenishment leads time for the availability check.

Note

There is no point in maintaining the total replenishment leads time field for materials procured externally. In external procurement, the system adds the processing time from purchasing, the planned delivery time, and the goods rec Eipt processing time and uses this total as the replenishment leads time for a availability check with replenishment leads Time.
