In case there is an integration
scenario for which a function module (FM) is exposed to external applications an
performance point of view is important to be considered. It may happen that the
FM with complex interface occurs performance issues.
What is meant by complex
interface? Basically if there are any complex or nested data types within
IMPORT/EXPORT/CHANGING parameters of the FM.
Complex
data types - are made up of other data types. A distinction is
made here between structured types and table types.
Nested structures
– are structures that in turn contain one or more other structures as
components.
To identify the FM which
may have performance problem you can use report RSRFCXC. The report should be
used before exposing the FM. Output of the report is evaluation of every FM’s parameters
whether it may have a problem and also how to correct it.
