When wanting to clear dynalinks between two forms, you can clear the dynalinks on the DS on the second form. See example below.

Clear DynaLinks
public void init()
{
;

super();

  if (element.args()     && element.args().caller()     && (element.args().caller().name() == formStr     (PurchTable)))
{
InventTable_ds.query().dataSourceTable(tableNum(InventTable)).clearDynalinks();
}
}

What does this mean: "The form datasource query object does not support changing its AllowCrossCompany property after the form has executed the query."?

I have made a form with datasources vendtable and vendtrans. Inside vendtable_ds.executequery() looks like this: QueryBuildDataSource queryBuildDatasource ,queryBDS_VendTrans_Invoice; ; queryBuildDatasource = this.query().dataSourceTable(tablenum(vendtable)); queryBDS_VendTrans_Invoice = this.query().dataSourceTable(tablenum(vendtrans)); if (curext() == "MASTERCOMP") { this.query().allowCrossCompany(true); } else { this.query().allowCrossCompany(false); } //FilterVendorName = stringedit control on form if (FilterVendorName.text()) { queryBuildDatasource.addRange(fieldNum(VendTable,Name)).value(strfmt("*%1*", FilterVendorName.text())); } else { queryBuildDatasource.clearRange(fieldNum(VendTable,Name)); } //FilterInvoiceNumber = stringedit control on form if (FilterInvoiceNumber.valueStr() == "") { queryBDS_VendTrans_Invoice.enabled(false); } else { queryBDS_VendTrans_Invoice.enabled(true); queryBDS_VendTrans_In...

Passing values between form and class

Class name is EmplDuplication and Form is EmplTable . void clicked() {    MenuFunction mf;    args args = new Args();    ;     args.record(EmplTable);     mf = new menufunction(identifierstr(EmplDuplication), MenuItemType::Action); mf.run(args); } Meanwhile, in the main() method of the EmplDuplication class, we need to put this Axapta x++ code to get the datasource: static void main(Args args) {     EmplDuplication EmplDuplication; EmplTable localEmplTable; ;     if(args.record().TableId == tablenum(EmplTable)) localEmplTable = args.record();     ... }
