Error description
A 3270 application is invoked via transaction id plus user data. So from a blank screen the user enters "FORM DPSTP". They have recorded a flow using SFM terminal recorder, generated the LINK3270 service adaptor (specifying Startup Transaction Data = FORM DPSTP), and deployed the flow to the CICS Service Flow Runtime. During execution of the service flow, the application receives control. The application first does a RECEIVE. However, the application does not see any data in the buffer, not even the transaction ID. Preliminary analysis indicates there may be some problems in DFHMAVCP.

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: Service Flow Runtime (SFR) receives an * * empty buffer on an EXEC CICS RECEIVE. * **************************************************************** * RECOMMENDATION: * **************************************************************** In the reported problem, an SFR application was interfacing with CICS via the LINK3270 bridge, this architecture uses commareas and structures to transfer data between the 'backend' (CICS), and the 'front end' (SFR). However, a path exists in DFHMAVCP where on initial invocation, data from the input buffer on the initial EXEC CICS RECEIVE is not moved to the RECEIVE VECTOR in SFR. As a consequence, a field that was expected to be populated was blank. When this happened, the Service Flow Runtime stopped executing.
Problem conclusion
DFHMAVCP has been amended and will now correctly process the input buffer to the RECEIVE VECTOR on initial invocation.
