Hi:
A search of support.sas.com reveals this usage note which explains that you cannot append RTF files together with ODS:

A search of this forum reveals a previous forum posting on this topic with some suggested workarounds:

1) put all your SAS code within one ODS RTF "sandwich" -- so that the parts/sections of your document are built by SAS from multiple procedures.
2) assemble your multiple RTF files in Microsoft Word or some other Word processor
3) post-process the RTF files with a program to selectively remove the RTF control characters that define either the beginning or end of a file.
