Problems wirh TableExtension and Values

(0) ShareShare
ReportReport
Posted on by 69

Hi there
I added a new table (customer N. and Name, plus additional infos) plus ListPage. works.

 
Now I want to integrate those table values into corresponding customer cards. 
I added an extension for the customer table. I see those fields in the inspector when I open the customer card. so that seemed to work. 


the fields are flowfields type lookup from the original table. 

BUT the values from the new table (which I add via List) are not copied over to the extension table fields. 

my syntax is 

field(60102; NEWFIELD; Format)
        {
            Caption = Field Name;
            FieldClass = FlowField;
            CalcFormula = lookup(NewTable.Column where(CustomerNo  = field("No.")));

//CustomerNo is one of the columns in the new table, and "No." is the PK of the customer-Table I try to extend. 

Could you please point me as to what I am doing wrong ?
Thanks in advance

    Did you add those fields to the Customer Card page?

    FlowFields values will be shown once you added them to the pages or use CALCFIELDS(fields) in the code to work with.

    perfect. I thought I was nuts. that works like a charm. I thought it copies the values anyways. but I guess the lookup only "löooks it up" when needed ? (when fields have to be shown) ?

    Use Record.CalcFields(Field/s).
