What are FlowFields?
FlowFields are not physical fields that are stored in the database. They are a description of a calculation and a location for the result to be displayed. Because the information in FlowFields exists only at run time, values in FlowFields are automatically initialized to 0 (zero).
How do I create a flow field in Navision?
To create a FlowField
- On the Tools menu, choose Object Designer.
- Select the line for the field that you want to define as a FlowField, such as the Amount field.
- On the View menu, choose Properties.
- In the FieldClass property field, select FlowField from the drop-down list.
What is flow filter in Navision?
In FlowFilter fields, a user can enter a filter value via the user interface in an application that will affect the calculation of a FlowField. FlowFilter fields are not saved in the database. Instead, they are stored for each window on an individual computer so users have their own filters.
What is Sumindexfield in Navision?
In Dynamics NAV there are SumIndexFields that can be used for cases like this. This technology lets you calculate the sums of numeric data type (Decimal, Integer, BigInteger, and Duration) columns in tables, even in tables with thousands of records very fast.
What is Sumindex field in Navision?
NAV provides an easy way to calculate totals of numeric columns (Decimal, Integer, BigInteger, Duration) swiftly using SumIndexFields. You must associate fields that are to be totaled to a key; you may associate multiple fields to multiple keys. Behind the scenes NAV uses the SIFT to calculate FlowFields.
How do I use FlowFilter in Business Central?
You use FlowFilter fields to set ranges on the calculations that are shown in FlowFields. For example, if a FlowField contains the total of customer entries, then you can use a FlowFilter to see the total for a single month or range of months. In this example, the FlowFilter field is a date field.
What is a vector field in mathematics?
In vector calculus and physics, a vector field is an assignment of a vector to each point in a subset of space. For instance, a vector field in the plane can be visualised as a collection of arrows with a given magnitude and direction, each attached to a point in the plane.

How do you use CalcSums in Business Central?
CalcSums method [Ok :=] Record. CalcSums (Field1, [Field2],…); For CalcSums, a key that contains the SumIndexFields must be selected as the current key. Similar to CalcFields, CalcSums uses the current filter settings when it performs the calculation.
What is velocity field in physics?
The quantity v(x, y,z,t) is called the velocity vector field. It can be thought of at each instant in time as a collection of vectors, one for each point in space whose direction and magnitude describes the direction and magnitude of the velocity of the fluid at that point (Figure 28.1).
What is 1d flow?
A one-dimensional flow is one which involves zero transverse components of flow. Uniform flow. The flow is defined as uniform flow when in the flow field the velocity and other hydrodynamic parameters do not change from point to point at any instant of time.
How do you find a vector function?
A vector-valued function is a function of the form ⇀r(t)=f(t)ˆi+g(t)ˆj or ⇀r(t)=f(t)ˆi+g(t)ˆj+h(t)ˆk, where the component functions f, g, and h are real-valued functions of the parameter t. The graph of a vector-valued function of the form ⇀r(t)=f(t)ˆi+g(t)ˆj is called a plane curve.
What is vector field example?
Examples
- A vector field for the movement of air on Earth will associate for every point on the surface of the Earth a vector with the wind speed and direction for that point.
- Velocity field of a moving fluid.
Why velocity is a vector?
Velocity has both magnitude and direction that is why it is a vector quantity. Whereas, Speed has only magnitude and no direction that is why it is a scalar quantity.
What is called velocity?
Velocity is the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. 60 km/h northbound).
What is 1d/2d 3d flow?
Term one, two or three dimensional flow refers to the number of space coordinated required to describe a flow. It appears that any physical flow is generally three-dimensional.
