qFRC Outbound Queue error "No mapping function module entered in SMOFSUBTAB"

Hi,

When I Checked the queue in SMQ1 in the ERP system, I found 3 different system errors but going to start with the error “No mapping function module entered in SMOFSUBTAB”. The status on this is SYSFAIL with a date of 11/11/2011 and next date 07/23/2012. It has 80,338 entries. Once I go into this queue a little farther it appears the majority of the statuses from what I can see have a Transaction recorded.

I went looking for this error and found some notes that stated I should check table CRMSUBTAB but it is dealing with CRM and CRM objects and this is for SRM.

Application: SRM

Object Name: R3BD_VENDOR_MAIN

Function module: BAPI_CRM_SAVE

SMQ1 has about 80,000 entries on this Queue name and I am wondering if there is a program to remove all these entries once it has completed its task or why does it keep the entries? In the past if we get to many entries in this tcode (SMQ1), it causes issues for other systems that are interfaced between ERP and CRM to not work correctly. I am wondering how to keep this clean or do I need to keep these entries or can they somehow be deleted. What is the purpose of keeping them?

Thanks,

Lisa
