Calculating the Planned Delivery Time
Use
Use this function to calculate and change the planned delivery time. Using the documents in the system, the system calculates the number of days between the order being placed with the vendor and actual goods receipt. You can also use the planned delivery times calculated by the system in the master data as the planned delivery time.
By using this function you can achieve more efficient goods procurement from your vendor and therefore avoid overstock and out-of-stock situations.
Features
Until now, manual maintenance of data for the planned delivery time took place in three different places in the system:
The values maintained manually here are, however, mostly based on past experience and can quickly become obsolete as the behavior of the vendor changes.
Using transaction WPDTC you can call the function for calculating the planned delivery time and:
To calculate the planned delivery time, the system determines the number of days between the order being placed with the vendor and the actual goods receipt for a freely definable combination of vendor, plant, material, purchasing organization and vendor subrange.
The function supports you in your decision of whether you want to keep the manually maintained planned delivery time or replace it with the calculated planned delivery time. You can decide this for each individual value in the master data for the vendor, material and purchasing info record.
Note that by changing the planned delivery time you can affect procurement.
Important: The system calculates the planned delivery time in calendar days not working days.
Example
You notice that you have been getting increasingly more out-of-stock situations in your distribution center recently for a certain article from a vendor. You suspect that there is a discrepancy between the planned delivery time that has been entered in the system manually and the actual delivery time. Using the function for calculating the planned delivery time you can determine exactly how many days have passed between placing the order with your vendor and actual goods receipt. You compare the planned delivery time that has been entered manually with the planned delivery time calculated by the system. You establish that the vendor now requires three days longer to make the delivery that the date entered manually for the planned delivery time. You decide to copy the planned delivery time calculated by the system to the master data.
