Multiple Schedule Lines during MRP run

[Former Member]

Hello,

During MRP run system is creating multiple schedule lines for same delivery date. Could any one help me out, why system is creating multiple schedule lines for same delivery date instead of a single schedule line.

MRP type: PD

Lot Size: TB

Example: 16.04.2012             SA111111/00010           qty1

               16.04.2012             SA111111/00010           qty1

               16.04.2012             SA111111/00010           qty1 

               16.04.2012             SA111111/00010           qty1

Expected :

               16.04.2012             SA111111/00010           qty4

Hi,

Check in MD04 if you have schedule lines with exception messages. If you have these exception messages then in ME38 you will see multiple lines as you will have 1 line per exception message.

Each of these lines are there because the exception message is telling you that the parts are probably needed earlier but the system is not able to plan these there (backward/forward scheduling principle of MRP).

Normally if you would process the release from ME38 or ME84 the vendor will only get 1 line with the total requirement for that date.

The system gives you a line per exception so that you can manually adjust these dates as per suggestion of the exception. This you would do after discussion with your vendor on the possibility of delivering these parts earlier then the settings that you did in the scheduling agreement (planned delivery time and GR processing time).
