Hello,

I'm trying add additional display method to InventSum datasource on InventOnhandItem form.

I attached my code below. I'm have debbuged this and always _inventSum equals "No data selected".

Can anyone suggest how it should be done correctly?

Thanks.

[ExtensionOf(formDataSourceStr(InventOnhandItem, InventSum))]
final class InventOnhandItem_XXX_Extension
{
    display Qty MyDisplay(InventSum _inventSum)
    {
        InventSum inventSum;
        FormDataSource InventSum_ds = _inventSum.datasource();
        FormDataSource InventDim_ds  = InventSum_ds.formRun().dataSource("InventDim");

        return InventSum.MyMethod(_inventSum, InventDim_ds);
    }
}

Instead of inventsum.datasource, give this.cursor();

I am not sure you can create a display method in form datasource. Ideally I will create that in table level and add that to a form as a new field.

Hi, You can get InventDim table buffer using below code, provided InventSum_ds is not empty.

InventDim inventDim = InventDim_ds.cursor();

I have a display method created on the InventSum datasoure of the InventOnhandItem form. Based on the debugging I did on this method, _inventSum is "No data selected"

This method calls the myMethod from the InventSum table extension.

[ExtensionOf(formDataSourceStr(InventOnhandItem, InventSum))] final class InventOnhandItem_InventSum_XXX_Extension { display Qty myDisplay(InventSum _inventSum) { FormDataSource inventSum_ds = _inventSum.datasource(); InventSum inventSum = inventSum_ds.cursor(); FormDataSource inventDim_ds = inventSum_ds.formRun().dataSource("InventDim"); return InventSum.MyMethod(_inventSum, InventDim_ds); } }

[ExtensionOf(tableStr(InventSum))] final class InventSum_XXX_Extension { public Qty myMethod(InventSum _inventSum, FormDataSource _ds) { InventTrans inventTrans; InventDim inventDim; Common common = formJoinedRecord(_inventSum, _ds); if(common.TableId == tableNum(InventDim)) { inventDim = common as InventDim; } if(inventDim.InventLocationId) { return 99; } return 0; } }

The requirement is that the display is to show a value of 99 if the 'Location' storage dimension is enabled and not empty for the row.
I have the same logic in AX12 and there it works without any problem. I'm trying to get it into D365, but with no results.

Could you please help me?

Hi,

[ExtensionOf(formDataSourceStr(InventOnhandItem, InventSum))] final class InventOnhandItem_InventSum_XXX_Extension { display Qty myDisplay(InventSum _inventSum) { FormDataSource inventDim_ds = this.formRun().dataSource("InventDim"); return _inventSum.MyMethod(inventDim_ds); } }

[ExtensionOf(tableStr(InventSum))] final class InventSum_XXX_Extension { public Qty myMethod(FormDataSource _ds) { InventDim inventDim; inventDim = _ds.cursor(); if(inventDim.InventLocationId) { return 99; } return 0; } }

Please try the above logic and check if it works.
