Creating multiple assignments with batch upload

am Creating multiple assignments with batch upload but i get the following errors;

PL0003: Column cannot be mapped to any question in the questionnaire.
File name: VISIT2_UGANDA NATIONAL PANEL SURVEY 2017-- COMMUNITY MODULE–.tab
Column: Id ( )

PL0007: One or more parent Id column is missing.
File name: VISIT2_UGANDA NATIONAL PANEL SURVEY 2017-- COMMUNITY MODULE–.tab
Column: interview__id ( )

What would be the problem?

Francis, there are two problems, one is that a column cannot be mapped to any question in the questionnaire and another one is that one or more parent id columns is (are) missing. This could be a problem of the user preparing the assignment files, or it could be a result of a recent changes described here:
