Hi,
I have learnt here in the Community that I can define a variable in the script so that it is filled with a value on the GUI, basically using two equal_signs and the 'SET' command.
Usually that works fine. For some reason, however, it doesn't work in an app I am currently working on.
Maybe one of you can imagine why that is or where the error is.
In the app I'm working on, there is a rather large straight_table_chart. To make it clearer, I want to give the user a possibility of selecting which fields he/she wants to see.
Now, in my app, I have a field >> __fields_to_display << from an Inline_table. That has a Hide_Prefix so it doesn't show up in a statusbox which would be quite confusing as this is not a selection supposed to limit the amount of data.
<=> What this actually does (or is supposed to do) is that for every field in this Inline_table, there is a variable. That is supposed to query the presence of this field in the output of a Getfieldselections() command and if any field is present, the corresponding variable should take on the value 1, otherwise it should be -1.
The code in the script is like this:
>> SET v_show_calculation = = IF(INDEX(Getfieldselections(__Detailfelder), 'Berechnung') > 0, 1, -1) <<
It seems not to work - at least, not reliably, not always.
I'll try out if it might be because of the Hide_Prefix. Though I have tried out that Index() function and it works reliably on the GUI.
Thanks for any ideas!
Best regards,
