By the way, this is a great way to avoid a million custom RFCs in your application, and contrary to popular belief, this function is supported by SAP.

Hi Glory,

If you search on RFC_READ_TABLE going back a few years, you will see a number of threads which address this subject in great detail.  There are also some other issues which are defined which will also prevent some other technical problems with using this RFC as well as some very detailed examples.

Glory,

This exception occurs when the rows of data being returned are too wide.  You can prevent this by specifying exactly which columns you want return from the table in the FIELDS parameter.  For example, in your table PLAF, pass the following to FIELDS and you should get a result back:

PLNUM

MATNR

PLWRK

PWWRK

PAART

BESKZ

SOBES

GSMNG

TLMNG

AVMNG

Normally you should start with a limited number of columns from the table.  Some of the columns do not execute well and it takes some experimenting to figure out which fields will cause the error message.  Worst case start with a single column.  Also limit the number of rows returned to 10 or 20 until you figure out what works and what does not.

Hi Glory,

  Please refer to the following document: http://scn.sap.com/docs/DOC-7050

This should solve the problem.
