Hello Forum,
I am looking for a solution to the following issue:
We are a plant manufacturer and handle our customer projects in SAP PS. For each project there is also an SD order, in which the order items correspond and are linked to a WBS element. However, the WBS elements are our cost objects. These are divided into asset components according to the asset structure. In principle, the system has existed in this form for quite a long time, but we do not use networks, for example.
Today, we write our planned project costs (cost of goods manufactured) in principle as a total plan value per WBS element (summarized on level 2) via primary cost planning vicariously to a cost element (technically primary cost planning in CJ40 or via the Excel upload in CJR2). My problem is that this planning is very rough and often very inaccurate, since the planned costs are estimated "pi by thumb" and it is also difficult for the planners to estimate which costs are still to come during the course of the project. At the same time, however, there is also a bill of material for each WBS element to be planned, and I would like to use the material cost estimate to determine the expected HC per WBS. This is technically possible, but I don't want to have to create countless calculations manually.
My question is therefore, is there a good way to calculate the project BOM for project planning and also to integrate this data into project reporting? In addition, it would be desirable to be able to recalculate the project BOM or all the WBS elements contained in it when the occasion arises.
I hope I was able to describe my request in a halfway understandable way. I would be very grateful for ideas and suggestions.
Many greetings
Stephan
