SAP and the Thinking Process

Building stronger Current Reality Trees

Part II

 

In this article, I´m going to continue on the topic started in part one. As mentioned in the previous text, SAP can support you very well in constructing Current Reality Tree. Now we will continue with the next two examples.

 

to remember, we are talking about the same tree as in part one

Current Reality Tree

Entity nr. 124 says: “We have an unnecessary inventory”. There are many ways to mininge the data from SAP to support this claim. You can gain the sum of the value kept in your inventory and WIP (work in progress). For these purposes, SAP provides its own standard transactions. But there can be another point of view. If one of your problems, whilst you are constructing a current reality tree, is lack of capacity, then it is useful to examine how much capacity ( or time ) is held in your inventory. Of course, there could be other reasons for doing it in this way. This approach is not difficult. The first step is building an interval table with materials and their current inventories. The next step is delivering all needed times for producing these from their working plans. The last step is calculating the desired result.

Here is my coding example:


Entity nr. 124 says: “We are measured according to local optimum” This is, unfortunately, the most common way how companies evaluate their productivity for a plant. From my point of view, the reason is “ it has always been done this way” and it is easy to understand and calculate. But in fact, almost nobody cares, that this approach is flawed. An explanation of my statement is not the aim of this article, but you can find it in The Theory Of Constraint. The old way for the productivity evaluation goes like this, but it can differ from plant to plant: In my example, each worker is assessed in a particular period of time. Its productive times are gathered from the DB-table AFRU and then compared against its attendance.

Here is the ABAP class for this action :

As you can see, there are plenty of ways how to mine data from SAP for supporting facts not only for the use in current reality trees but for other processes which need some facts for decision making. In this two-part article, I have shown options and approaches how you can do it and I hope SAP will help you in your own quests.
