Issue on MC74 transfer plan to Demand management

Hi, PP gurus:

I created plan for material via MC87 as below:

material: HT***

M102008 M022008 M032008

sales 300 600 600

production 300 600 600

then I transfer plan to demand management via MC74, I viewed the PIR of HT*** via MD63, the result as below was not as supposed:

02.01.2008 03.01.2008 04.01.2008 w02.2008 w03.2008 w04.2008 w05.2008 M02.2008 M03.2008

HT*** 13.637 13.637 13.637 68.181 68.182 68.182 54.545 600 600

Who can throw some light to me how to find the cause and fix it?

Any advice is appreciatd. Thanks a lot

John
