Hi @jiangxm80 ,
Thank you for reaching out to the Microsoft Fabric Forum Community.
1. your issue happens because you're applying a filter like keepfilters(__DS2FilterTable) even when __DS2FilterTable is blank.
2. In dax, that's not allowed — keepfilters(blank) doesn’t create a valid filter context, so it throws this error:
"the true/false expression does not specify a column."
3. To fix it, apply each filter only if it has a value. wrap each calculatetable step with if, instead of passing all filters at once.
If solution was helpful, please mark it as Accept Answer.
Feel free to let us know if you have any further questions—we’re here to help!
Hi @jiangxm80
Your DAX script uses TREATAS to dynamically apply filters on the SalesForecastDetails table. To apply these filters conditionally based on other conditions, you can introduce logic in your DAX query by combining the IF, SWITCH, or conditional logic functions.
Below is an example of how you can adapt your script to include conditional logic for applying the filters:
VAR __DS0FilterTable =
IF(
NOT(ISBLANK(@{variables('strVersionNo')})),
TREATAS({@{variables('strVersionNo')}}, 'SalesForecastDetails'[VersionNo]),
BLANK()
)
VAR __DS1FilterTable =
IF(
NOT(ISBLANK(@{variables('strProductGroup')})),
TREATAS({@{variables('strProductGroup')}}, 'SalesForecastDetails'[ProductGroup]),
BLANK()
)
VAR __DS2FilterTable =
IF(
NOT(ISBLANK(@{variables('strCategory')})),
TREATAS({@{variables('strCategory')}}, 'SalesForecastDetails'[Category]),
BLANK()
)
VAR __DS0Core =
CALCULATETABLE(
SUMMARIZE(
'SalesForecastDetails',
'SalesForecastDetails'[YearNo],
'SalesForecastDetails'[MonthNo],
'SalesForecastDetails'[VersionNo],
'SalesForecastDetails'[Region],
'SalesForecastDetails'[Area],
'SalesForecastDetails'[ProductGroup],
'SalesForecastDetails'[Category],
'SalesForecastDetails'[SubCategory],
'SalesForecastDetails'[ProductNo],
'SalesForecastDetails'[ProductSpec],
'SalesForecastDetails'[FinalQty_Accum],
'SalesForecastDetails'[FinalAmt_Accum],
'SalesForecastDetails'[Left],
'SalesForecastDetails'[LeftAmt],
'SalesForecastDetails'[Sample],
'SalesForecastDetails'[SampleAmt],
'SalesForecastDetails'[Inv],
'SalesForecastDetails'[InvAmt],
'SalesForecastDetails'[FinalQty],
'SalesForecastDetails'[FinalAmt],
'SalesForecastDetails'[LInv],
'SalesForecastDetails'[LInvAmt]
),
KEEPFILTERS(__DS0FilterTable),
KEEPFILTERS(__DS1FilterTable),
KEEPFILTERS(__DS2FilterTable),
'SalesForecastDetails'[FinalQty_Accum] <> 0
|| 'SalesForecastDetails'[FinalAmt_Accum] <> 0
|| 'SalesForecastDetails'[Left] <> 0
|| 'SalesForecastDetails'[LeftAmt] <> 0
|| 'SalesForecastDetails'[Sample] <> 0
|| 'SalesForecastDetails'[SampleAmt] <> 0
|| 'SalesForecastDetails'[Inv] <> 0
|| 'SalesForecastDetails'[InvAmt] <> 0
|| 'SalesForecastDetails'[FinalQty] <> 0
|| 'SalesForecastDetails'[FinalAmt] <> 0
|| 'SalesForecastDetails'[LInv] <> 0
|| 'SalesForecastDetails'[LInvAmt] <> 0
)

You can extend the logic further by introducing additional conditions (e.g., based on other column values or external variables) in the IF statements.

Thanks for the help.
it seems some error as the folloiwng.
{"type":1,"value":"Query (8, 13) Too few arguments were passed to the ISBLANK function. The minimum argument count for the function is 1."}},
Hi @jiangxm80 -
The error thrown is stating that the ISBLANK function is being called without a required argument. The argument could be a value or an expression to check for blank. In your script, it looks like one of the variables @{variables('strVersionNo')}, @{variables('strProductGroup')}, or @{variables('strCategory')} might not be successfully resolved, which could be why the ISBLANK function is executing without an argument.
Here are some suggestions:
VAR __DS0FilterTable =
IF(
NOT(ISBLANK("Version1")),
TREATAS({"Version1"}, 'SalesForecastDetails'[VersionNo]),
BLANK()
)
VAR __DS1FilterTable =
IF(
NOT(ISBLANK("ProductGroup1")),
TREATAS({"ProductGroup1"}, 'SalesForecastDetails'[ProductGroup]),
BLANK()
)
VAR __DS2FilterTable =
IF(
NOT(ISBLANK("Category1")),
TREATAS({"Category1"}, 'SalesForecastDetails'[Category]),
BLANK()
)
VAR __DS0Core =
CALCULATETABLE(
SUMMARIZE(
'SalesForecastDetails',
'SalesForecastDetails'[YearNo],
'SalesForecastDetails'[MonthNo],
'SalesForecastDetails'[VersionNo],
'SalesForecastDetails'[Region],
'SalesForecastDetails'[Area],
'SalesForecastDetails'[ProductGroup],

thanks, I have tried, should be fine now.
but there is a new issue, when the __DS2FilterTable is BLANK(), it will show some error as the following.
The True/False expression does not specify a column. Each True/False expressions used as a table filter expression must refer to exactly one column
