2. In col 1 define the code of the set routine (e.g. 01)
3. Columns from 2 to 6 define the document field and subfield codes from the library from which record is copied.to document field and subfield codes of local library to which record is copied.
For example, in UNIMARC title statement is 200 and in MARC21 it is 245. In UNIMARC topical subject is 606 and in MARC21 it is 650:
! 2 3 4 5 6 7
!!-!!!!!-!!!!!!!!!!-!!!!!-!-!!!!!!!!!!-!!!!
01 245## ancnp 2001 adfhi
01 650## 606##

4. Edit ./xxx01/tab/tab_fix
5. Define a new routine name in col.1 for the fix procedure fix_doc_tab04_nn (where nn is the entry in tab04):
! 1 2 3
!!!!!-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!>
04-01 fix_doc_tab04_01

6. Restart PC Server
7. Edit ./xxx01/pc_tab/catalog/fix_doc.lng. Add a new line with in col.1 the routine name defined in ./xxx01/tab/tab_fix, and add a description in col.4
