the formula must contain contain at least one field or function Eikon API

Hi, we have some fields to retreive data with python, this fields are for balanceSheet, IncomeSheet and CashFlow Data.

p = {

'Period': 'FY0'

, 'reportingState':'Orig'

, 'curn': currency

, 'Scale':'6'

, 'SORTA':'LISeq'

, 'CH':'Fd'

, 'IncludeOldYE' :'No'

, 'ReportType':'Latest'

, 'Edate' : '-10FY'

, 'FRQ':'FY'

, 'transpose':'y'

, 'Sdate' : '0FY'

, 'FXRate' : 'PeriodEnd'

, 'NULL' : 'blank'

}

df, err = ek.get_data(['BAP.LM'], ['TR.F.BalanceSheet.fieldName','TR.F.BalanceSheet.fielddescription', 'TR.F.BalanceSheet.date','TR.F.BalanceSheet'], parameters = p )

We handle the translate for the all fields, so we obtain the name of the field in english to build this json Example:

{

"key": "TR.F.AssetParticipFactorIssue ",t

"lang": {

"es": "Factor de participación de activos: tema específico ",

"en": "Asset Participation Factor - Issue Specific"

}

}

but for the followings fields ge got The formula must contain at least one field or function vía excel.

TR.F.PPEExclROUTangCapLeaseNet

TR.F.PPEExclROUTangCapLeaseGross

TR.F.PPEExclROUTangCapLeaseAccumDepr

TR.F.TotOpLeaseLiab

TR.F.FinOpLeaseLiabTot

TR.F.DebtInclFinOpLeaseLiab

TR.F.InterestEarnLiabAvg

I wondering if there is a way to obtain at least the name of the fields even if the field does not have data.

Thanks
