One of the pieces of data that different companies must maintain, involving the useful life of a device, food, merchandise, raw material, etc., is the exact delivery dates in SAP. For their control and determination, SAP proposes the OE (Delivery Orders) indicators and exact dates.
To know if an order position is subject to this determination, we will have to assign the following indicator in the material master:
We access MM01 and in the purchasing tab we indicate the center where it intervenes:

Controls whether, in addition to creating delivery orders for supplies, you can also create delivery orders with exact delivery date/time for a material within a purchasing delivery schedule.

If this indicator is set exact dates in SAP, The position will be copied to the additional data when creating a delivery plan. It comes predefined where this parameter is used, but it can be specified with the value #1, and we have a field that is automatically filled in, and you can do so in the order.

What is the purpose of this type of control within an organization and how should it be used?
As I always like to transfer the fields to examples that we have from our daily lives, we take this example to the fact that we have a dairy products company where we receive milk every "x" time from a supplier in the area where we supply ourselves to carry out the packaging process, after quality controls.

Traceability, on the one hand, is very important in case there is an alteration or a simple anomaly, of which we have had many throughout our history, and to pull the thread to know where it came from. The date of entry into our organization is also necessary to know the exact date on which we worked on the product and how it arrived to us.
Traceability systems are key tools for maintaining product safety. This allows us to understand every stage of the process. If we detect a problem at any stage, we can identify the source of the problem and, if the product has reached its final destination, take appropriate action.
By automating this field for material entered into SAP, we can record every incoming order we have in our company in the system and maintain a permanent record.
This can be measured and recorded in our company, and we can have that record with a specific delivery plan where we can record the exact date on which our milk arrived from the specific supplier, it arrived at our factory at the exact time and date, before being packaged, for example.
.
You can avoid problems, both in this example and in many others, if we detect a defect on January X, but we know that we didn't address it until February 1. Therefore, the accounting for this error is not attributed to us, but to the supplier in question.
If we want to display by tables which materials have these fields enabled in our system, we will have to go to MARC and select the FABKZ field.
