Financial PL View with Custom Layout Help

Hi Zdenison 

It isn't currenlty supported to selective disable the expand icons. You can however, write a condition so when a certain category is expanded, it won't show the lower level hierarchy. Try this sample measure

// Hide the measure value when drilling down to the account code level
// for specific summary categories to avoid showing duplicate totals
IF (
    // Check if we're at the detail level (account code and name is visible)
    ISINSCOPE ( 'table'[account code and name] )
        // AND the current row is a summary/total category
        && 'table'[account category] IN { "Total Revenue", "Total Income", "Etc" },
    // If both conditions are true, return blank (hide the value)
    BLANK (),
    // Otherwise, show the normal P&L measure value
    [pnl measure]
)
