Field help (DPOTAB) 

This field is used in the selection of postings to be unmatched. The SELECT key is used to select or deselect a posting. The "*" character appears or disappears from the field according to the case. The Save button unmatches all the postings selected with the character "*". The Criteria button is used to load a group of postings in the grid. The postings can then be unmatched. The Auto button automatically unmatches all the account postings and bank postings corresponding to certain criteria.
