I only want to export or filter fields of copy belonging to a given iln
is this possible ?

thanks

Hi @jaohbib,

it's not possible to filter for specific fields which belongs to a copy of an ILN. You have to split the record first: Please take a look at the experimental explode[^1] command.

Regarding your example: You have to split the record first and filter for records which belongs the a given ILN:

$ pica explode -s local DUMP.dat --where '010@.a == "20"' -o out.dat
$ pica explode -s copy DUMP.dat --where '010@.a == "20"' -o out.dat

The first command creates a new dump, containing only records with all copies of ILN 20. The second command creates a new dump, containing records for each copy of an ILN-20 section; all other records/copies will be discarded.

NB: There is a known bug, that fields (except 101@) of the local level are not processed correctly. This bugfix is still on the TODO-list. This could affect your use case.

I am still working on it

[jaohbib]

I use pica explode -s copy DUMP.dat --where '101@.a == "20"' -o out2.dat

to get only my copies but I receive only an empty file . Is this another bug or is there a Problem with my data

I Added a minimal Dump file containing a single record.

DUMP.txt

Ok, this is releated to the bug I mentioned. I took a look into the code, and I think I can fix this soon.
