Hi,

Does someone know if there is a custom function that can copy a field from a child table to a repeating field? The child table field is a container.

I need this because it's not possible to put a portal in a portal...

Maybe I could create a recursive custom function using GetNthRecord, but does this function works on containers?

Thanks

No custom function is necessary: use GetNthRecord() in conjunction with Get (CalculationRepetitionNumber).

That is exactly what I just tried and it doesn't work. The result only shows me the first record in the repeating field.

Does not work, only shows the first record in the first repeating field.

GetNthRecord ( comp_sale_PHOTOS__generals::photo; Get ( CalculationRepetitionNumber ))

Does work and shows the 4th record in the first repetition

GetNthRecord ( comp_sale_PHOTOS__generals::photo; 4)

From the comparables table, the relations are Comparables >-- Sales --< Photos

I don't know and really use repetitions, only in special cases...

As with any repeating field calculation, you must use Extend() with non-repeating fields referenced in the formula:

GetNthRecord ( Extend ( Photos::ContainerField ) ; Get ( CalculationRepetitionNumber ) )

 

Or, even better:

 

Let ( [

n = Count ( Photos::PhotoID ) ;

i = Get ( CalculationRepetitionNumber )

] ;

Case ( i <= n ; GetNthRecord ( Extend ( Photos::ContainerField ) ; i ) )

)

Thank you very much!
