Requirements Determination Procedure for Investment Buying 

Use

The system uses the requirements determination function to find out which articles can be considered for investment buying during a particular period.

Procedure

You can calculate requirements in two different ways:

·        In the background

Usually the system has to process a large amount of data, making background processing the better option. You define how often the report is run, for example daily. You have various options for narrowing down and controlling your selection.

·        Online

It only makes sense to run the report online if you narrow down the data to be processed to an absolute minimum. You would do this, for example, to determine requirements for an individual article.

Requirements are determined and follow-on documents generated directly afterwards in the following sequence:

...

       1.      Program RMEBEIN4 determines all relevant condition changes for the desired period. If you do not use direct creation of worklist entries, you can specify in Customizing that it should also write condition change pointers.

       2.      If any relevant purchasing conditions have changed, the system determines the order price on the date of the change for the articles concerned, and calculates the return on investment to decide whether forward-buying would make economic sense.

       3.      If forward-buying makes sense, the system generates follow-on documents in line with the control parameters.

You have the following control options:

·        Limiting selection

You can narrow down the amount of data analyzed by entering selection values, such as a particular vendor, article or site.

·        General control parameters

You can control which type of follow-on document is generated and whether the vendor with the most favorable conditions is always selected.

Result

The requirements determination run results in a log being generated. You can evaluate this log using the analysis function. This shows how the stock situation will develop in the weeks and months to come if you make use of forward-buying and helps you decide whether buying would be a good investment.
