In this step you define the possible fields of the grid field catalog that can be selected when creating or maintaining the condition table grid.
Before you include a new field in the grid field catalog, you should check whether the existing fields
of the field catalog are sufficient for your requirements. If you want to use a field in the grid determination
that is not used in the Standard version, you must include this in the field catalog. You can only include fields of the tables J_3AKOMJ, J_3AKOMK or J_3AKOMP.
