Hello,

This error comes when there is a break of RFC connection between SAP and Vertex. It seems that during LSMW, multiple calls are made from SAP to Vertex and system has less resources assigned to handled such situations hence the RFC connection is failing in between. Please ask your BASIS team to analyze the SAP Vertex RFC health and increase resources if needed. 

Thanks
