Hi Sathwik,
For Open Text you need to have access to Open Text KC. From there you may download relevant integration document and software and follow the steps sequentially.
Just to give you an idea:
1) You will be required to download certain add-ons for Open Text. If you are an SAP customer and holding valid license for Open Text, you are allowed to download the same.
2) Apply this add-on on the relevant SAP system, either ECC or NW.
3) Install Open Text s/w
4) Configure ECC with Open Text based on configuration document available at Open Text KC.
