Thanks a lot for your quick answer.
My question was not formulated properly. I know that PPMs can model finite tank planning, but during most of the document PP-PI is mentioned in ECC side. However, in my ECC system there will not be PP-PI but discrete planning. To make things worst, it seems that manually created PPMs in APO are allways discrete PP ones, PP-PI PPMs come only from the CIF (or I missed something).
So the right question is: can finite tank planning be modelled with PPMs created in APO?
