Filter function returns no records for a data source of the Electronic reporting (GER) framework configured to fetch data from a temporary table of the Dynamics 365 for Operation application

GER framework allows to manage formats that can be used for generation of electronic documents. Application tables can be used as data sources for such GER formats. The function FILTER can be applied to such data sources in GER expressions to fetch the only desired records from the related application table for generation of electronic documents. The problem occurs when the function FILTER is applied in a GER expression for a data source fetching data from a temporary application table – such call returns no records.

To work around this issue, the WHERE function can be used in a GER expression instead of the FILTER one. Read this page to find more details about GER functions: https://ax.help.dynamics.com/en/wiki/general-electronic-reporting-ger-formula-designer/ .
