With<span>\u00a0this release, we bring you several new features that help building your solutions as extensions. We also include a large number of resolved GitHub issues. See the list of closed bugs here: <a href=\"https:\/\/github.com\/Microsoft\/AL\/milestone\/19?closed=1\">closed bugs in August<\/a><\/span>.<\/p>\n<p lang=\"en-US\">This Developer Preview is available only through the Ready to Go program. Read more at<span>\u00a0<\/span><a href=\"http:\/\/aka.ms\/readytogo\">http:\/\/aka.ms\/readytogo<\/a>. To get all fixes and features described in this post please make sure you are running an image with a build number\u00a02.0.41872 or newer.<\/p>\n<h2>New virtual tables for Report Data Items and all Page Control fields<\/h2>\n<p>The following two new virtual tables are added to reflect more info about request pages and reports:<\/p>\n<ul>\n<li style=\"font-family: Calibri;font-size: 11pt\"><span style=\"font-family: Calibri;font-size: 11.0pt\"><strong>All Control Fields<\/strong> (ID 2000000202)<\/span>\n<ul>\n<li style=\"font-family: Calibri;font-size: 11pt\"><span style=\"font-family: Calibri;font-size: 11.0pt\">This table contains information about page controls on regular pages, as well as on request pages in reports and XMLports. The primary key is &#8220;Object Type&#8221;, &#8220;Object ID&#8221;, and &#8220;Control ID&#8221;, where &#8220;Object Type&#8221; could have a value of <strong>Report<\/strong>, <strong>XMLport<\/strong>, or <strong>Page<\/strong>.<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"margin-top: 0;margin-bottom: 0;vertical-align: middle\"><span style=\"font-family: Calibri;font-size: 11.0pt\"><strong>Report Data Items<\/strong> (ID 2000000203)<\/span>\n<ul>\n<li style=\"margin-top: 0;margin-bottom: 0;vertical-align: middle\"><span style=\"font-family: Calibri;font-size: 11.0pt\">This table reflects information about individual data items in a report, for example: &#8220;Indentation Level&#8221;, &#8220;Related Table ID&#8221;, &#8220;Request Filter Fields&#8221;, etc.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p style=\"margin: 0in;font-family: Calibri;font-size: 11.0pt\" lang=\"en-US\">With the help of these new tables, it is possible now, for example, to generate the report parameters XML string without actually invoking the report request page. Try this <a href=\"https:\/\/msdnshared.blob.core.windows.net\/media\/2018\/08\/codeunit-report-xml-parameters-builder.txt\">code example<\/a>.<\/p>\n<h2>Translating Base App help using AL extensions<\/h2>\n<p>It is now possible to create AL extensions that override the default help link for Business Central and re-direct users pressing the Help button to another website. This also enables translating the help link for Base App objects.<\/p>\n<p>In order to do so, we&#8217;ve introduced two new properties in the manifest of AL extensions: &#8216;helpBaseUrl&#8217; and &#8216;supportedLocales&#8217;. The &#8216;helpBaseUrl&#8217; property represents the URL that will be used to override Microsoft&#8217;s default help link (<a href=\"https:\/\/docs.microsoft.com\/%7b0%7d\/en-us\/dynamics-365\/blog\/business-central\">https:\/\/docs.microsoft.com\/{0}\/en-us\/dynamics-365\/blog\/business-central<\/a>). This URL must contain a placeholder &#8216;{0}&#8217; for the user&#8217;s locale culture and should point to a website that must be forked from <a href=\"https:\/\/github.com\/MicrosoftDocs\/dynamics365smb-docs\">https:\/\/github.com\/MicrosoftDocs\/dynamics365smb-docs<\/a> in order to follow the same structure that Microsoft&#8217;s help follows. The property &#8216;supportedLocales&#8217; is used to specify the list of locales (in the format language2-country2\/region2) that are supported by the URL provided and then by the translation app. If the user&#8217;s current locale is among the &#8216;supportedLocales&#8217; of your extension the user will be re-directed to the help base URL that you specified.\u00a0 The settings in the app.json file look like this:<\/p>\n<p>&nbsp;<\/p>\n<pre>\u00a0 \"helpBaseUrl\": \"<a href=\"https:\/\/www.mydocumentationwebsite.com\/%7b0%7d\/business-central\/\">https:\/\/www.mydocumentationwebsite.com\/{0}\/business-central\/<\/a>\",\n\n\u00a0 \"supportedLocales\": [\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \"da-DK\"\u00a0 ]<\/pre>\n<p>&nbsp;<\/p>\n<p>Note that this feature is not available for per-tenant extensions and a rule has been implemented for it in the PTE analyzer. See <a href=\"https:\/\/docs.microsoft.com\/en-us\/en-us\/dynamics-365\/blog\/business-central\/dev-itpro\/developer\/devenv-codeanalyzer-pertenantextensioncop-rules\">PerTenantExtensionCop Analyzer<\/a>.<\/p>\n<p>&nbsp;<\/p>\n<h2>Adding help links with user locale on new created objects<\/h2>\n<p>We previously added the ability to add static help links in new created pages, reports, or XMLports. For more information, see<\/p>\n<div>\n<div><span><a href=\"https:\/\/docs.microsoft.com\/en-us\/en-us\/dynamics-365\/blog\/business-central\/dev-itpro\/developer\/devenv-adding-help-links-from-pages-tables-xmlports\">Adding Help Links from Pages, Reports, and XMLports<\/a>.\u00a0<\/span>It is now also possible to include a placeholder for the user locale in these links. From code, you will define the HelpLink as follows, including the {0} placeholder:<\/div>\n<\/div>\n<p><strong><\/strong><\/p>\n<pre style=\"padding-left: 30px\">page 50100 MyPage\n\n{\n\n    HelpLink = '<a href=\"https:\/\/www.mydocumentationwebsite.com\/%7b0%7d\/business-central\/my-page\">https:\/\/www.mydocumentationwebsite.com\/<strong>{0}<\/strong>\/business-central\/my-page<\/a>';\n\n}<\/pre>\n<p>And the placeholder is then filled in according to the app.json file locale setting:<\/p>\n<pre style=\"padding-left: 30px\">\"supportedLocales\": [\n\n\"da-DK\", \"en-US\"]\n\n\n<\/pre>\n<p>In case the user is using one of the supported locales, the supported locale will be inserted in the help link. If the user is not using one of the supported locales, the first locale specified in the &#8216;supportedLocales&#8217; setting will be considered default and be inserted in the URL.<\/p>\n<h2>Field group extensiblity<\/h2>\n<p>Field groups can now be extended from a table extension with the use of the <strong>addlast<\/strong> construct. It allows for adding more fields to the end of a field group.<\/p>\n<p lang=\"en-US\"><a href=\"https:\/\/www.microsoft.com\/en-us\/dynamics-365\/blog\/wp-content\/uploads\/2018\/08\/fieldgroups.png\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.microsoft.com\/en-us\/dynamics-365\/blog\/wp-content\/uploads\/2018\/08\/fieldgroups.png\" alt=\"\" width=\"481\" height=\"254\" class=\"alignnone size-full wp-image-18285\" \/><\/a><\/p>\n<h2>Report substitution is possible from extensions<\/h2>\n<p>Extensions can now replace built-in reports by subscribing to the <strong>OnAfterSubstituteReport<\/strong> event emitted by <strong>Codeunit 44 &#8211; ReportManagement<\/strong>.
