Systematic reuse of features and related ERP product customizations would improve software quality and save implementation time.
In our previous research, we have developed a tool-based approach supporting feature-based reuse of ERP product customizations. Our tool environment automatically infers reusable features from requirements and their associated implementation artifacts.
Furthermore, it allows domain experts to search for features based on natural language requirement descriptions representing the needs of new customers. Matching features can be automatically deployed to a new ERP product.
In this paper, we present an industrial evaluation of our tool-based approach conducted together with an Austrian small- to medium-sized enterprise. A domain expert used our approach to identify matching features for 20 randomly selected requirements for new customer products and identified matching features for 17 of the 20 requirements.
We compared the time needed to identify and deploy the candidate features with the time required to implement the requirements from scratch. The paper is available at ACM. August Leave a comment. I recently faced a customer requirement in Dynamics AX where a customer needs two lookups in report dialog.
Michael has already documented in his blog how to overwrite a lookup in dialog. In order to override the lookup methods a RunBaseReport class is needed to call the the report. Implement the abstract method lastValueElementName and provide the name of the report to start. In my case the report is called WarehouseReport. Create a menu item and start the class.
Right click the lookup fields and from the setup form note the name of the lookup fields. According to michaels blog overwrite the dialogPostRun method. Here you can defined that you want to overwrite methods and link an object with the overwritten methods.
Next implement the code for the lookup on the second lookup field in the dialog. In the last step overwrite the init method in the report and set the range according to the values from the lookup fields. July 1 Comment. June Leave a comment. A often recurring requirement is a graphical inventory overview showing the usage of locations. There are many ways how to implement such a solution.
One simple way is to use data shapes in Visio and link them to Dynamics Ax data. Since every warehouse is different, you have to create a separate Visio drawing for each one. Visio provides you with good standard shapes to draw a floor plan. In this example I am using a simple drawing of a warehouse with one door and 12 locations. Create one Visio file per warehouse and save it on a file share.
Next create a view for each warehouse on the Dynamics AX database. Ask you DBA to secure access to the view for your users. Go through the wizard and connect to your SQL Server and the view you have just created.
In the Visio drawing panel select the first square that represents a location. Right click on a record in the external data grid and select Link to selected shape. A chain symbol will appear next to the record, showing you that this record is new linked to a shape in your drawing. Right click on the shape that is now linked to a record in the external data. In the shapes context menu go to shape data and open edit data graphic.
Here you can add and format the column values from the record to the shape. You only need to selected the copy and then right click on the corresponding row in the external data and link to shape.
This will update the shape data with the values from the new record. Finally some work is needed in Dynamics AX to view the Visio drawing. At the InventLocation table add a new field using the FileName extended data type. Add the field in the InventLocation form, so you can provide a Visio file path for each InventLocation. Load inventLocation. Create a display menu item for the form and add it to the InventLocation form. Make sure to set the InventLocation as data source for the menu item.
Now if you have created a Visio document and provided the file path in the InventLocation record, by clicking on the menu item you can see a graphical representation of your warehouse.

The report had to meet the following requirements:. Next we defined and loaded the report definition from Excel. We used to sheets, one for the definition of the two time frames and one for the group definition.
Like initially described the Accounts sheet defines the grouping of postings regarding their account number. For example in line 2 and 3 postings on accounts Postings on accounts Both Excel worksheets were loaded into PowerBI.
Next we changed the query of LedgerJournalTrans and added the parameter to the query. With the parameter in the query and the default values set to the parameters the dataset did not change. Next we added a new function to the LedgerJournalTrans.
PowerBI inspects the query statement and creates function parameter for each parameter in the query. In PowerBI a function call can be used like a row wise join. A function can be added by using the used defined function button in the query editor. So we added the function call to the Accounts dataset, i. PowerBI will popup a warning that function calls can have a security impact.
Per default PowerBI adds the fields from the function call result with the function name prefix e. Transdate, GetPostings. AmountCurCredit, etc. To get the amount values for each of the two periods, defined in the Daterange Excel sheet, we added 4 additional columns to the Accounts. A debit and credit column for period 1 and period 2. Finally we used a matrix to display the values from the Accounts dataset and grouped it by Name and Accounts. Injecting range values in a query is not the best way to do this.
April 4 Comments. This is an example how to print customer and item specific labels in Dynamics for Finance and Operations. The labels shall be printed directly within the sales order form at the sales line grid.
Create a new table containing the following five fields. The table will hold the configuration which report and design to use for which combination of customer and item. Create a new class called ItemLabelContract, which will be the data contract class for the report.
Create a new controller class called ItemLabelContract. This class will be called from the menu item in the sales order form. It takes the SalesLine as parameter and decides which report and design to use.
ReportName, setup. ReportDesign ;. SalesId ; contract. LineNum ; contract. SalesQty ;. Create a temporary InMemory table called ItemLabelTmp for the report data set including the following five columns:.
Create the report data provide class. ItemId,false,false ;. ItemId; itemLabelTmp. BarCode; itemLabelTmp. Create a new report and add the report data provider class as source. Create at least two designs. Create a new form using a the Simple List pattern to manipulate the configuration table form. Create a new display menu item for the form and add it e. Create a form extension for the SalesTable form.
Create new sales orders and test the different configurations and labels.

Help us translate the latest version. Use Ethereum to create decentralized applications or "dapps" that utilize the benefits of cryptocurrency and blockchain technology. These dapps can be trustworthy, meaning that once they are deployed to Ethereum, they will always run as programmed. They can control digital assets in order to create new kinds of financial applications.
As part of exploring the blockchain technology, and specifically the Ethereum ecosystem, I have settled on an IoT-related use case around solar energy grids. You can read more background in the first article in this series. In this post, I am going to focus on building a small private blockchain that I will later use to deploy Smart Contracts and build my solar energy marketplace demo on. I am going to use an Azure virtual machine to start a reasonably powerful mining node, and a Raspberry Pi 3 to simulate an on-premises equipment running a lighter, non-mining node, but which can still be involved in blockchain transactions. We will be using geth , the Go Ethereum client , to set up our cluster.
