Difference result between MD03 and RMMRP000

Hello gurus,

we have a problem with the MRP running for some materials. When we run the program RMMRP000, the date of the planned orders of some materials  is not rescheduled. However, when we run manually the MRP in the transaction MD03, the planned orders are rescheduled properly.

For instance, for the following material, when we run the program RMMRP000 with this selection data:

The planned order is not rescheduled to 15.01.2014:

When we run the transaction MD03 with the following data:

The planned order is rescheduled to 15.01.2014:

Thank you.

Best regards.
