Error popup when using /guixt/select: We are developing new functions in which we use the /guixt/select function module for database access. This works well but I now have a problem in a new statement that results in an error popup telling me that the Select statement is not correct. What can be the reason?

This happens when you specify an incorrect field name or table name. Use transaction ST22 to display the latest ABAP short dump. It contains a detailed error message that shows the wrong table name or field name.
