## Landed Cost Autocost Manual Override Enhancement with Microsoft Dynamics 365 Finance and Supply Chain Management

Supply Chain Management has become much more different to forecast and manage recently. I remember when a supply chain professional could have negotiated logistics rates for all movement, handling, and storage of product, and reasonably expected the negotiated rates would hold firm for the length of the agreements, frequently rolling into multi-year contracts that were stable and predictable.

Those times have passed.

To be a great supply chain professional requires not only knowledge of the ever-changing world environment, it also requires a way to capture, apply, and easily modify the costing structure for the application of the landed cost portion of your marketable goods.

## Using the Autocost Manual Override Enhancement in Dynamics 365

Microsoft Dynamics 365 Finance & Supply Chain (D365 F&SCM) provides the platform for the capture and application of these fluctuating costs via the Landed Cost module, but the maintenance of the costing portion within the module could be more efficient. Updating the Autocost tables for the newly applicable costs is a manual process that needs to occur before creating a new Voyage if these costs have changed once again . Often, the supply chain professional is only made aware of the changes at the time a shipment is tendered. Normally this would require the user to go into the associated Landed cost tables and manually update each before the Voyage record could be created with the new charges.

The new Autocost manual override enhancement in Dynamics 365 removes the need to update all the Autocost tables before Voyage creation. This is done by having a function trigger during Voyage creation that will open a popup modification table once the From and To shipping ports are selected. This popup searches the Autocost tables and displays all matching Journey template Autocost records. These records display the existing cost criteria and can be edited on the fly for the new applicable charges. No prework needed. The newly applied cost data is then saved to the associated Autocost records. This works for both Purchase order Voyages and Transfer order Voyages. If this enhancement is applied in conjunction with the Transfer order automation enhancement , it will also create all the associated sub-records such that no prework is ever required for a Transfer order voyage to be created.

Below are the sequential images of the Autocost enhancement process in Dynamics 365 F&SCM.

## Showing the Voyage creation screen:

1) Add to new shipping container

2) Create shipping container(s):

3) Popup window that allows direct entry of the Autocost amounts, category, apportionment method, and Minimum charge amounts. The cost area allows the user to move between all applicable cost areas within the same popup screen to modify all desired charges in one place.

4) Once the user selects OK, the new charges are saved to the Autocost table and applied to the newly created Landed Cost voyage container.

The LXI trim adds luxury and convenience, showcasing upgraded upholstery, a larger infotainment display, and a robust suite of safety features, making it perfect for families seeking both function and style.

In terms of amenities, the 2021 Chrysler Voyager does not disappoint. It features an impressive array of technology options, including Apple CarPlay and Android Auto compatibility, allowing seamless connectivity while on the go. Ample storage space, versatile seating configurations, and an available rear entertainment system further enhance the family-friendly environment. Safety is a top priority, with advanced safety features such as adaptive cruise control, blind-spot monitoring, and automatic emergency braking providing peace of mind.

- Page 913 TI-89 Titanium / Voyage™ 200 Error Messages This section lists error messages that may be displayed when input or internal errors are encountered. The number to the left of each error message represents an internal error number that is not displayed. If the error occurs inside a Try...EndTry block, the error number is stored in system variable errornum.
- Page 914 Break The ´ key was pressed during a long calculation or during program execution. Checksum error Circular definition This message is displayed to avoid running out of memory during infinite replacement of variable values during simplification. For example, a+1! a, where a is an undefined variable, will cause this error.
- Page 915 First argument of nSolve must be a univariate equation The first argument must be an equation, and the equation cannot contain a non-valued variable other than the variable of interest. For example, nSolve(3x^2- 4=0, x) is a valid equation; however, nSolve(3x^2- 4, x) is not an equation, and nSolve(3x^2- y=0,x) is not a univariate equation because y has no value in this example.

For example, x+ - y (x plus minus y) is invalid; whereas, x+ y (x plus negative y) is correct. Too few arguments The expression or equation is missing one or more arguments.
- Page 919 Note: Domain of result may be smaller TI-89 Titanium / Voyage™ 200 Modes This section describes the modes of the TI-89 Titanium /Voyage™ 200 and lists the possible settings of each mode. These mode settings are displayed when you press Graph Specifies the type of graphs you can plot.
- Page 920 Note: If you select NORMAL, but the answer cannot be displayed in the number of digits selected by Display Digits, the TI-89 Titanium / Voyage™ 200 displays the answer in SCIENTIFIC notation. If Display Digits = FLOAT, scientific notation will be used for exponents of 12 or more and exponents of -4 or less.
- Page 921 Vector Format Determines how 2-element and 3-element vectors are displayed. You can enter vectors in any of the coordinate systems. 1:RECTANGULAR Coordinates are in terms of x, y, and z. For example, [3,5,2] represents x = 3, y = 5, and z = 2.
- Page 922 Exact/Approx Specifies how fractional and symbolic expressions are calculated and displayed. By retaining rational and symbolic forms in the EXACT setting, the TI-89 Titanium / Voyage™ 200 increases precision by eliminating most numeric rounding errors.
- Page 923 Base Lets you perform calculations by entering numbers in decimal, binary, or hexadecimal form. 1:DEC Decimal numbers use 0 - 9 in the base 10 format 2:HEX Hexadecimal numbers use 0 - 9 and A - F in the base 16 format. 3:BIN Binary numbers use 0 and 1 in the base 2 format.
- Page 924 Custom Units Lets you select custom defaults. This mode is dimmed until you select Unit System, 3:CUSTOM. Language Lets you localize the TI-89 Titanium / Voyage 200 into one of several languages, ™ depending on which language Flash applications are installed.
- Page 925 TI-89 Titanium / Voyage™ 200 Character Codes The char() function lets you refer to any character by its numeric character code. For example, to display 2 on the Program I/O screen, use Disp char(127). You can use ord() to find the numeric code of a character. For example, ord("A") returns 65.
- Page 926 TI-89 Titanium Key Codes The getKey() function returns a value that corresponds to the last key pressed, according to the tables shown in this section. For example, if your program contains a getKey() function, pressing 2 ˆ will return a value of 273.
