2108166 - Duplicate schedule lines are created with the same date by MRP


Two schedule lines are created as below with the same date 07.01.2015 which are supposed to be combined to one schedule line and the quantities of each schedule line doesn't match the requirements quantity in each planning calendar period.


In the material master, the lot size Z1 which calculates the lot size according to the planning calendar is defined and the planning calendar has the periods as followings. In the transaction code MD04, the independent requirements of LSF from 07.01.2015 to 14.01.2015 seem to be in the 2 planning calendar periods 2015/02 and 2015/03 so the MRP should create the 2 schedule lines for each period at different date, e.g. at the start date of each period, but they have same dates now.
