5.2.8 Column Precision for Instrument Table

You can change the member-id column size from number(14) to number(20), but the new size will impact FTP and ALM Engines as follows:

  • Values/fields read by the engine are restricted to the size that the C++ variables can hold within the engine memory. Having a value larger than the allowed precision can cause the engine to read the value incorrectly.
  • Changing the size of the fields that these engines write into does not affect the precision of the results.
  • An upgrade could rollback such changes unless you remember to do a model merge.
