RFC Calling Error

[Former Member]

Hello All,

We are experiencing an issue with (RFC_READ_TABLE )RFCs.

We are on MII version 11.5 build(15)

and calling an R/3 ECC 6.0 system.

We are executing RFC Function Module RFC_READ_TABLE in SAP and we are getting the output values (table details ) if we give the input (table name).

The same when we are calling from Jco block...and passing the Input parameter as table name , i am getting the conncetion error Jco Block end action failed.

Can anyone help me out.

Thanks,

Hi ,

Change the Input parameter table name to xml in transaction property if you are using string.

Also click on Assign Xml in link editor instead Assign value.

That may solve your problem.

Regards,

Padma

Shanmugan,

Please save the Request segment from your JCo action block (use a tracer) and post it here. There are any number of things that could be causing the problem.

Michael,

This is the tracer output.

<?xml version="1.0" encoding="UTF-8"?><RFC_READ_TABLE><INPUT><DELIMITER>SPACE</DELIMITER><NO_DATA>SPACE</NO_DATA><QUERY_TABLE>T00W1</QUERY_TABLE><ROWCOUNT>0</ROWCOUNT><ROWSKIPS>0</ROWSKIPS></INPUT><TABLES><DATA><item><WA/></item></DATA><FIELDS><item><FIELDNAME/><OFFSET/><LENGTH/><TYPE/><FIELDTEXT/></item></FIELDS><OPTIONS><item><TEXT/></item></OPTIONS></TABLES></RFC_READ_TABLE>

Shanmugan,

You have identified no fields to retrieve and your Rowcount is 0. Please identify one or two fields and set your rowcount to 20 and rerun.

Do a search on RFC_READ_TABLE for this year (not the default 90 day window) in this forum. There are several good posts on the use of this RFC.

Regards,

Mike
