Wolfgang, thank you for your advice. Unfortunalty it does not work. I changed the COMPONENT file to:
% === comp_A1.tex ==== \startcomponent[comp A1] \project[proj_Test.tex] \product[prod_A.tex] \startsection[title=comp_A1, reference=comp_A1] Reference to page comp_A1: \at[comp_A1] Reference to page comp_B1: \at[comp_B1] Reference to page refB::comp_B1: \at[refB::comp_B1] \stopsection \stopcomponent % ==================== I run Context with the PRODUCT file prod_A.tex . The second reference is marked with ?? . The third reference is invisible, nothing is shown. After writing "\at[refB::]" in the PRODUCT file "prod_A.tex" the second reference works as expected (even without the prefix), the third reference (with the prefix) is still invisible. The log file of the PRODUCT file prod_A.tex states: job > passes > integrating list 'prod_B.tuc' into 'prod_A' Wolfgang Schuster wrote: > Am 18.08.2025 um 13:49 schrieb M U via ntg-context: > > I have some problems in cross-referencing in products of a project. > > To say it quite frankly: I have no clue.
