I remember just started to implement the time allocated to my first project is an integrated project, open the project will start when the Party A project manager said to me: We are on the PDMIs to, and ERP integration, if not integration, there is no need on this project. Was fearless and did not know so what's difficult to integrate, then they too would like down, the results had come to a time when most perplexing and ERP integration - ERP want a lot of data PDM inside at all. So, no way, then go back to the implementation of the adjustment of a lot of content - but at that time head of ERP projects do not do not know what the data inside the PDM, the enterprises MRP computing in the end to how much data, so companies do not put all the responsibility onto me, then finally the ERP data are needed to ready, ERP also proposed integrated approach to the problem - they only support the txt file, and no way to , we have developed a small tool to export the data to integrate into a txt file to the ERP.
Several years later, I went to companies that pay a return visit, Party A project manager told me - you did not even use that interface! ? I was shocked how it was. He told me that their businesses are outsourcing parts of more than 90 products into the series, variant is particularly high. If the PDM in the design, and then export to ERP, ERP and then do the production plan, the finished product may have been produced. So they are now basically no use this interface, but directly in the ERP which to copy a similar product BOM and then after simple modification can be produced under the program areas.
To do this project, I read a lot about the integration of PDM and ERP articles, until the Party that the project manager interface useless to tell me when I came to understand PDM and ERP is in fact not a simple technical problem, an interface At least three aspects to consider:
1, the interface approach: are generally three kinds of modes: the middle of data, control, integration, exchange of visits between the database;
2, interface elements: all call BOM, PDM and ERP in the BOM in the BOM is completely different concepts, different enterprises, on the understanding of BOM are not the same, the same business, different business sectors, the demands on the BOM not the same.
3, interface timing: When imported into the ERP in? How to ensure the accuracy of the data interface?
Later, the implementation of the Department of boss told me that you have this interface is one of the most simple interface, the real complexity is to change. That is, if the data in the PDM changes, how to notify to the ERP, ERP how to deal with, how to change the data tag, this is the most complex.
Unfortunately, too complex, nothing has been changed with the integration of the project, but I firmly remember: PDM and ERP is the most difficult to mark and handling change. But I still do not understand, in the end Difficulties.
