Getting started with the OpenERP MRP module

Getting started with the MRP module can be a daunting enterprise, and it is easy  to get lost at it. But actually it is easier than it seems. I will cover the functional elements you need to get started with the MRP module. I will not cover how to do that, it is already covered in the documentation.

In order to start with the MRP module, you just need four pieces of information:

  1. Product information; the first information item you need. Which products you are planning to sell and procure.
  2. Bill of Materials, sometimes called formulas. They are a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, components, parts and the quantities of each needed to manufacture an end product.
  3. Stock information, pretty much how much inventory you have at hand. If you don’t have this information, you can’t even get started. MRP uses inventory information to determine when and how much to procure.
  4. Master Procurement Schedule; this provides the list of the products you need to procure (either purchase or manufacture) and when you need them. This can be provided by the stock_planning module. Or you could keep an spreadsheet updated with your procurement needs and create the procurement orders from there.

If you are planning on implementing the MRP module, you need to assess the four points I described above. Chances are bill of materials are maintained in paper or spreadsheets. The stock information might be maintained by an information system within the company. But at the end of the day, you will need to assess the quality of the bill of materials. Implementing them will be the longest item in the MRP implementation plan, and you can’t take shortcuts over there. Chances are you will need someone manually checking they are fine, and that you will need to import them manually (which might be the healthiest thing to do).

Well, just wanted to cover some information issues that come up when you are implementing the MRP module.

Cheers,
