We are having a repeated error after enabling RTBC. Our material POs always has an error "Requisition PRXXXX, cannot be sent to the external system because a connection failure has occurred". Our ECC counterpart says they are receiving the PR copy in ECC but with errors. While they investigate I came accross in CIG, Procurement Project Wizard -> Step 4 Cross Reference -> Parameter -> RequisitionImportAsyncPullRequest. What is the purpose of this parameter? Will it help in the RTBC issue that we have?
