tab-mapping producing multiple 852s in holdings record?

• Article Type: General
• Product: Aleph
• Product Version: 20

Description:
I am using abc50/tab/tab_mapping to create a new holdings record when using file-90.

There are two issues:

1. Why are there two 852s being created when the 049 has only the specified value-

2. Why did the 852 $h and $i not get created from the data in the bib record?

Resolution:
1) I found that wild cards are not to be used instead of the holding code in tab_mapping.
There is a "default holding code" parameter in file-90, that can be used if records do not have any 049. But if there are ####### in tab_mapping, they will be performed *in addition* to the holding code, which may result in duplicate values.

2) After #####, system stops reading the table. If you put the RPLCYBP code *before* the line with ##### wild cards, call number should be created as expected. The general ###### line will be performed, too, but there will be no duplicate values, just because there are no 05099 in these records.
