Function modules are stored (their source code) in one of these includes. This means that all FM are stored in memory.</P><P></P><P>If you want prevent this - take out this FM out of group into its own group. Or split fm of this one big group into more smaller based on some logic.</P></BODY></HTML> Thu, 25 Feb 2010 09:43:43 GMT https://community.sap.com/t5/application-development-and-automation-discussions/performance-problem-with-function-group/m-p/6682017#M1449748 Former Member 2010-02-25T09:43:43Z Re: Performance problem with Function Group https://community.sap.com/t5/application-development-and-automation-discussions/performance-problem-with-function-group/m-p/6682018#M1449749 <HTML><HEAD></HEAD><BODY><P>any other solutions please....</P></BODY></HTML> Thu, 25 Feb 2010 11:59:27 GMT https://community.sap.com/t5/application-development-and-automation-discussions/performance-problem-with-function-group/m-p/6682018#M1449749 Former Member 2010-02-25T11:59:27Z Re: Performance problem with Function Group https://community.sap.com/t5/application-development-and-automation-discussions/performance-problem-with-function-group/m-p/6682019#M1449750 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P></P><P>how did you come to the conclusion that your performance problems are related with the memory consumption</P><P>of the function group source / load?</P><P></P><P>Kind regards,</P><P></P><P>Hermann</P></BODY></HTML> Thu, 25 Feb 2010 12:16:04 GMT https://community.sap.com/t5/application-development-and-automation-discussions/performance-problem-with-function-group/m-p/6682019#M1449750 HermannGahm 2010-02-25T12:16:04Z Re: Performance problem with Function Group https://community.sap.com/t5/application-development-and-automation-discussions/performance-problem-with-function-group/m-p/6682020#M1449751 <HTML><HEAD></HEAD><BODY><P>The performance problem didn't come from loading the function group.
