Run a class in background–Asynchronies mode

This is not much of a new thing but a reminder. I feel it should be used more often in D365fFO. In prior versions we showed a progress bar and gave the user a nice feeling that something was processing. In D365fFO we need better a way. If you look at the Data Management, it has a workspace for this. Process runs in async and workspace shows us the status.

Code wise, it is pretty simple. Below is an example from standard code. I got it using “Find reference” feature in Visual Studio.

Any info or error messages will appear in the message centre. This is great as the user can continue doing their job without waiting.

Why am I writing about this?

I had a project recently where the a process was taking minutes to run. Based on the amount of data and what it was doing, I found it acceptable that it ran that long. When the user was running it, they perceive it as slow and they are waiting on the screen to refresh. I used runAsync and what do you know – happy customer.

AX - How to use Map and MapEnumerator

Similar to Set class, Map class allows you to associate one value (the key) with another value. Both the key and value can be any valid X++ type, including objects. The types of the key and the value are specified in the declaration of the map. The way in which maps are implemented means that access to the values is very fast. Below is a sample code that sets and retrieves values from a map. static void checkItemNameAliasDuplicate(Args _args) { inventTable inventTable; Map map; MapEnumerator mapEnumerator; NameAlias nameAlias; int counter = 0; ; map = new Map(Types::String, Types::Integer); //store into map while select inventTable { nameAlias = inventTable.NameAlias; if (!map.exists(nameAlias)) { map.insert(nameAlias, 1); } else { map.insert(nameAlias, map.lookup(nameAlias) + 1); } } //retrieve fro

AX - How to use Set and SetEnumerator

The Set class is used for the storage and retrieval of data from a collection in which the values of the elements contained are unique and serve as the key values according to which the data is automatically ordered. You can create a set of primitive data types or complex data types such as a Class, Record or Container. Below is sample of a set of records. static void _Set(Args _args) {     CustTable       custTable;     Set             set = new Set(Types::Record);     SetEnumerator   setEnumerator;     ;     while select custTable     {         if (custTable && !set.in(custTable))         {             set.add(custTable);         }     }     if (!set.empty())     {         setEnumerator = set.getEnumerator();         setEnumerator.reset();         while (setEnumerator.moveNext())         {             custTable = setEnumerator.current();             info(strfmt("Customer: %1",custTable.AccountNum));         }     } } Common mistake when creating a set of recIds

Import document handling (attachment) files #MSDyn365FO

Out of the box you have limited data entities for migrating attachments. If you search what is already in the AOT, you will see a few various examples. I suggest you look at the LedgerJournalAttachmentsEntity as it is the simplest and cleans to copy from. I wont go into detail but I will give a quick run down of what it looks like. Use the DocuRefEntity as your main datasource. It does most of the work for you. Set your table you want to import for as the child datasource Add the Key You will need to add the postLoad method. There is minor code to update the virtual field FileContents. Below is an export I did for the general journal attachments. The import zip structure should be the same way. It will create the usual artifacts such as the excel, manifest and package header xml files. You will see a Resources folder under that. If you drill down to the resources you will see the attachments. This is an export and it used the document GUID for uniqueness. The other thing is the extensi
