5.1.21 Column Precision for Instrument Table

You can increase the size of the columns to make them hold a value of larger precision, 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.
