Reposting Communication Documents in R/2 
When errors occur during the transmission of communication documents from the R/3 system to the R/2 host, once you correct the errors you must repost the corresponding communication documents in the R/2 System. You can identify errors (technical or logical) using the same procedures available for the R/3 System (see the flow chart under
Receiving Communication Documents in R/3).Once errors have been analyzed and corrected, you repost communication documents in the R/2 System using transaction TQ92.
Reposting from the Analysis Tool
This transaction can be started from the analysis tool (transaction TQ90) which is described in the previous section. From the global display in the analysis tool (see Step 2 above)
The system displays an overview of the communication documents with errors. The corresponding error message is also displayed for each communication document in the list.
To repost the communication document in the background, choose
Reposting Directly
To repost specific communication documents individually, you use transaction TQ92. Once you have entered the number of the corrected communication document in the Communication document field, the procedure is the same as described above beginning with step 3a.
Mail Control in the R/2 System
As in the R/3 System, when a communication document is received with errors in the R/2 System, a normal or express mail message can be sent to the user responsible (see
Mail Control in the R/3 System.)Assigning Mail Recipients
To assign users to receive mail messages for specific tasks in the R/2 System, you make entries in table 349M. In this table you enter the R/3 warehouse number, record type, recipient and whether or not an express mail message is to be sent.
There is no table, as in the R/3 System, which determines whether or not a Mail message is to be sent.
You can, however, modify some logging and additional functions in the data section of the receiving program (ML18KTOP). To enter this program you use transaction TM38. The parameters are in a so-called modification part at the end of the include.

If you modify any of these parameters in your system, please be aware that you may have to rework this Include after an official SAP system update.
