ASCII PdCum tab

The PDCum tabs controls how Petra imports and updates cumulative production data. In general, Petra attempts to add to existing production cums by matching the name, top and base in the imported data to cumulative values in the project. Without a good match, Petra will add a new cumulative production line to the database.

Ignore Dates When Updating PDCUM tables	By default, Petra uses dates to match production data. This option instead forces Petra to ignore the PDCUM dates and update the tables, potentially creating new PDCUM lines.
Use FmName Only to Match Existing Records	This option forces Petra to only use formation name to match production cums in the imported data to production cums already in the project.
Protect (Do Not Modify) ALTNAME on Existing Records	Protects the alternate name on the existing records and prevents it from being overwritten by the imported data.
Substitute Top for Missing Base Values	Copies the depth of the top of the PDCum to the base when the base is missing.
Substitute Base for Missing Top Values	Copies the depth of the base of the PDCum to the top when the top is missing.
