Hi everyone,

I am trying to conditionally block a field based on the legal entity. I made an extension of the salestable form, and datasource class Salesline, method active.

It builds well, but does not work. I guess I am doing something wrong. I hope that somebody is able to help me out:

ExtensionOf(formStr(SalesTable))]
public final class ELCWDSalesTableUS0008_Extension
{
    [DataSource]
    class SalesLine
    {
        int active(boolean _mcrFormPartUpdateOnly = false)
        {
            int     ret;
            next active(_mcrFormPartUpdateOnly);
            
            if(curExt()=="ENTNL")
            {
                SalesLine_ds.object(fieldNum(SalesLine, ShippingDateConfirmed)).allowedit(false);
            }
            
            return ret;
        }
    }
}

Put a breakpoint there and see what happens. Code looks ok but maybe company name is wrong or there is another place in the code that makes it editable again after active.

Hi,

Does the company used is correct? The maximum size of the dataAreaId is 4 char.

Hi Willem,

My first guess is the company condition. You used a hard-coded company name with 5 characters where the default is only allowing 4 characters as company ID.

Good morning! Thank you for your suggestions.

To make sure that the Legal Entity was not the problem, I removed this code and added a breakpoint. This has the same result: the field remains editable.

Also the breakpoint is not hit. Maybe the active method is not the right one in this form?

Visual studio mentions during debugging that the breakpoint will not be hit because symbols are not loaded. I double checked my settings, but the " Load symbols only for items in the solution" is unchecked as it is supposed to be.

hi

I can see that you want to create extension using COC.

Hi Uday!

Yes I used chain of command. Should I use event handler instead?

I read the article in your link. I tried to change my code to that example:

[ExtensionOf(FormDatasourceStr(Salestable,Salesline))] final class ELCWDSalesTableUS0008_Extension { int active(boolean _mcrFormPartUpdateOnly = false) { int ret; next active(_mcrFormPartUpdateOnly); SalesLine_ds.object(fieldNum(SalesLine, ShippingDateConfirmed)).allowedit(false); return ret; }

I get multiple errors:

Error The augmented class 'FormDataSource' provides a method by this name, but this method cannot be used as a chain of command method since the parameter profile does not match the original method.

Hi Willem,

You could use FormDataSourceEventHandler.

[FormDataSourceEventHandler(formDataSourceStr(SalesTable, SalesLine), FormDataSourceEventType::Activated)] public static void SalesLine_OnActivated(FormDataSource sender, FormDataSourceEventArgs e) { FormDataSource salesline_ds = sender.formRun().dataSource("SalesLine"); //if condition SalesLine_ds.object(fieldNum(SalesLine, ShippingDateConfirmed)).allowedit(false); }

Hi

[ExtensionOf(FormDatasourceStr(SalesTable,SalesLine))]

final class SalesTable_extension

{

int active()

{

int ret;

FormDataSource salesLineds;

salesLineds = this.formrun().datasource(FormDatasourceStr(SalesTable,SalesLine));

ret = next active();

salesLineds.object(fieldNum(SalesLine, ShippingDateConfirmed)).allowedit(false);

return ret;

}

}

Hi Will! Thanks for your help.

I changed to Event handler, but the field remains editable:

public static class ELCWDSalesTableUS0008_Extension { [FormDataSourceEventHandler(formDataSourceStr(SalesTable, SalesLine), FormDataSourceEventType::Activated)] public static void SalesLine_OnActivated(FormDataSource sender, FormDataSourceEventArgs e) { FormDataSource salesline_ds = sender.formRun().dataSource("SalesLine"); //if condition SalesLine_ds.object(fieldNum(SalesLine, ShippingDateConfirmed)).allowedit(false); } }

Ok. I Tried it on another field. This blocks well. So it seems ievgen is right: after the allowedit(false) it seems it is being enabled again. I will check and reply back.
