SUM/SUMIF Function In DAX

Please assist. Am i using the correct function in dax for SUM/SUMIF equilvalents in Dax, Also when do i use Calculate?

My Totals are inflated, my conversions from Excel to DAX, might not be correct.

Measure: Depreciation and amortisation in Excel(see Excel link for Formula), DAX:

WorkingCapitalMvtsInclProvisions =
[Other asset movements]

  • [Working capital - budget flex]
  • CALCULATE(
    SUM(‘ZTBR’[Amount in USD]),
    ‘ZTBR’[Roll_Up_Function] = “Provision movements”
    )
    Formula in Excel:

=-SUMIF(Details!B:B;‘Cash Flow’!G39;Details!G:G)

AND Disposals & impairment of fixed assets.

DAX:

Disposals & impairment of fixed assets =
CALCULATE(
SUM(‘ZTBR’[Amount in USD]),
‘ZTBR’[Roll_Up_Function] IN {
“Profit on disposal of pooling equipment”,
“Scrapped pooling equipment”,
“Impairment or valuation adjustment of pooling equipment”,
“Disposals or valuation adjustments of other fixed assets”
}
)
Excel Formula:

=SUM(K21:K24)
