Hi,
I try to immerse myself into Model mix planning in APO for automotive industry. I have a few questions.
1. can product structure and process structure be mapped using classical PP BOM and routing in SAP ECC system? If yes, a normal production version can be used and somehow linked to iPPE??
2. Can the iPPE be created in APO directly or it should be created in ECC and transferred to APO? My understanding is that we create iPPE in ECC and transfer it to APO to create a PDS out of it....
3. If no variants are used in ECC but just configurable materials should I maintain a dummy product structure header = dummy bom and a dummy routing header in iPPE object to maintain a consistency of iPPE structure? If yes, should this be done in ECC or in APO? Does that make sense / is reasonable?
4. can a dummy product structure (BOM) be maintained in APO iPPE object directly so that the iPPE structure is consistent or should this be done in ECC?
5. In our case only a structure node in iPPE is plan to be maintained for the finished product, under structure node a dummy component variant is plan to be maintained. A question here is that if I understand it right, we maintain the structure in iPPE directly. but what if it is planned to use a classical PP- BOM? will we then maintain both iPPE structure and a PP-BOM?? this does not make much sense to me as a beginner in Model Mix Planning in APO...
6. Can the iPPE object only have a dummy BOM and a dummy routing?
7. In our case it is planned that the line design will be carried out in SAP PLM and transfered to SAP APO = will create a line structure within iPPE in APO. I thought that if PLM is used, the line structure would be sent to ECC via Interface to create / update iPPE in ECC due to the fact the the iPPE should be maintained in ECC and just transferred to APO??/
8. How much sens makes usage of Model Mix Planning in APO if only the finished product is planned in APO and all the components in ECC using MRP?
do we need then iPPE or can we just use PP-BOM and PP-Routing = production version and make a PDS on APO side out of it?.
9.If we classify the final products into product families could we maintain takt times / production rates at final product family level (each product family is allocated to a line) .
10. It is planned that the APO iPPE will not have detailed process structure. A detailed routing should be created in ECC. A dummy routing header will be maintained in SAP APO iPPE object. Under dummy header a dummy resource will be assigned. This is to keep / maintain the consistency of the iPPE object. so much the theory... my question is if this make sense and if this will not create errors while generating PDS?
I am aware of so many questions and I did try to put them "on paper" so it is understandible...which menas that I would be happy about any good comment or hint or link that helps me to answer my questions / doubts.. thank you in advance!
best regards,
Pilvi
