Hi Jones,
Sincere Apologies for the delay in my response. I did what you had asked me to do and still it didnt work. Hence I did the following to make it work:
I made use of Remote Enable RFC for READ TEXT that is the FM /SAPDS/READ_TEXT' and called in an include which was part of RULE Assignment.
My approach was similar to the one mentioned in the blog:How To...Load and Convert SAP Long Text into HANA using SLT
The Only difference was I was using an Remote Enabled RFC for it to fetch texts from SRM/GRC and ECC.
Regards,
Pablo Ghosh Roy
