So if function modules is being invoked simultaneously, the change on one global variable will impact the value of the same variable on the other instance of function module. Is my understanding right so that the developers shall never use a global variable in a Idoc inbound processing function module?</P><P></P><P>YN Mao</P></BODY></HTML> Tue, 19 Jun 2012 09:16:01 GMT https://community.sap.com/t5/application-development-and-automation-discussions/global-variable-in-inbound-idoc-function-module/m-p/8792398#M1679310 Former Member 2012-06-19T09:16:01Z Re: Global Variable in Inbound IDoc Function Module https://community.sap.com/t5/application-development-and-automation-discussions/global-variable-in-inbound-idoc-function-module/m-p/8792399#M1679311 <HTML><HEAD></HEAD><BODY><P>The global function group memory is shared within the same internal session.
