MRP with PD, it doesn't want to show me UNPLREQ based on forecast.

Question

Hi guru's!
I work on a new project. I use PD as planification type.
The target is to take in account in MRP only the PLDORDER proposals (not converted in Production Order), the companie update the stock manually with MIGO to erase PldOrder at each new MRP run. (They don't want to create and manage master data as componants, BOM or routings)
Material master have forecast view, and historic of consumption are copied from past sales results.
They want to use a dynamic safety stock, which is calculated thanks to MP38. This lunch calculation of forecast collectively to create UNPLREQ in MRP every month based on the historic.
I've done the customizing, and my MRP work correctly : UNPLREQ was here and the update of stock with MIGO was good (after a MRP run PLDORDER were erased).
But after some change in customizing, I don't retreive my first situation, in fact UNPLREQ (neither none requirement) are shown now in my MRP.
I don't retrieve my mistake in customizing... Please, is somebody know where something can change the fact that you can't see the requirements in MRP??? the problem not comes from my material master data, i'm sure of that!! it's in the customizing.
I hope you have all need to answer.
Thanks in advance.

Dear R.Brahmankar,
Your note, even if it's for an old version of SAP, is helpfull for me. I will try to create my own planification type with the same configuration than PD but changing forcast to mandatory. I will test it and we will see after...
In fact, before my example "crash", I have tested plan. type VV and VM. So, as forcast is mandatory in this case but it's not work too, there is something which is "bizarre"!! Moreover, I've try the two way of enter forcast historic (non planned consumption and total consumption) for my article in forcast view.
JH,
My requirement was not replace in independant requirement (MD61).
Thanks, I will re-post something if I find a my mistake.!!
