November 17, 2010 I ran into a problem importing a number of records from a WP merge file into one of my databases. The panel uses absolute incrementation of its record number through a recursive panel link. A change to that from an autoincrementing field is the only change to this panel since I last imported a merge file.
This time, the first record in the merge file imported, and all successive records were discarded as duplicates. Since there were only a few, I entered them manually (only one field required in each case), with no problems. The question is, why did DP reject the last ten records in the file as duplicates. I exported the affected records in that panel to a WP merge file, and compared the exported file to my import file. The only differences were two empty fields at the end of each record, followed by the record number and the negative record number from the autoincrementing recursive link. 3 indexes. 1: Bk #, Author title, page numbers, etc, and record number 2: subject, record number 3: Hidden negative record number for the autoincrement. In the first two indexes there would be duplicates except for the record number, which is supposed to increment automatically and so prevent duplicates. One record for you to see what I mean Import file 03951^E Letham^E R.^E Westminster Assembly: ... in historical context^E ^E 52^E 2^E 53^E Q^E Church of England^E ^R Export file 03951^E Letham^E R.^E Westminster Assembly: ... in historical context^E ^E 52^E 2^E 53^E Q^E Church of England^E ^E ^E 8484^E -8484^E ^R Every record had either different page numbers or different subject line (Here "Church of England"), and that was sufficient As I read Ralph Alvy's book, there does not seem to be anything that would prevent the successive records being imported from incrementing, but it seems that failure to do that would be the only reason for calling the records duplicates and rejecting them. Any help?
