Ports Precision

Ports Precision

Precision is the maximum number of significant digits for numeric data types, or maximum number of characters for string data types. For numeric data types, precision includes scale.
You can tune the precision in Model repository mappings.
When mappings contain ports with a larger precision than required, the mapping performance degrades. Informatica recommends that you set the precision judiciously for all source ports, transformation ports, and target ports. For instance, if a string port can handle data of a maximum of 200 characters, set the precision to 200. Do not set the precision to a high value such as 1000.
