Send file to temp blob storage in #MSDyn365FO

In this post I will talk about sending a file to a temporary blob storage. A little warning before I get into it.

This is using the Microsoft’s blob storage that is provisioned for us. I haven’t given it a lot of thought on how it would behave in production. Take it at your own risk.

Lets start by looking back on a couple of posts last month on printing a report to a byte array.

You can use those sample pieces of code to get a report as a stream and send it to the below code.

if (stream)
{
    str fileName = 'myfile';
    str contentType = 'application/pdf';
    str fileExtension = SRSPrintDestinationSettings::findFileNameType(SRSReportFileFormat::PDF, SRSImageFileFormat::BMP);

    FileUploadTemporaryStorageStrategy fileUploadStrategy = new FileUploadTemporaryStorageStrategy();
    FileUploadTemporaryStorageResult fileUploadResult = fileUploadStrategy.uploadFile(stream, fileName + fileExtension, contentType , fileExtension);

    if (fileUploadResult == null || !fileUploadResult.getUploadStatus())
    {
        warning("@ApplicationPlatform:FileUploadFailed");
    }
    else
    {
        downloadUrl = fileUploadResult.getDownloadUrl();
        if (downloadUrl == "")
        {
            throw Exception::Error;
        }
    }
}

A download URL will be generated for you. The URL is going to be public and with an expiration (15 minutes I believe).

Below is an error if you try to access it after the expiration period.

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())     {    ...

Approve Workflow via email using template placeholders #Dyn365FO

Dynamics 365 for Finance and Operations has placeholders which can be inserted into the instructions. Normally you would want this to show up in the email that is sent. One of the most useful ones is the URL link to the exact record that you are approving. In the workflow configurations use the placeholder and build up your message. Towards the end it has workflow specific ones. The URL token is %Workflow.Link to web% . For the technical people the token is replaced in this class WorkflowDocumentField. This is what I inserted into my email template. <BODY> subject: %subject% <BR> message: %message% <BR> company: %company% <BR> for: %for% <BR> </BODY> Should look like this. The final result looks like this. If you debug these are the place holders that are put together.
