SAP IQ closely resembles OpenText, which I use in conjunction with the SAP ECC ERP system. However, for BW, I utilize SAP NLS instead of OpenText, which functions as a storage unit for my data. The process is straightforward as I move the data from SAP HANA to NLS. Generally, there isn't much activity with SAP NLS, and I only retrieve data from it occasionally upon request. It isn't a system that presents any daily challenges, and mostly, it remains inactive, managing my legacy data in the background. Overall, I'm satisfied with its performance, and I don't have any current plans to modify the system. We are using SAP IQ because it was available from SAP to support archiving. SAP BW, was SAP NLS. They never recommended an OpenText or there was no path to archiving in SAP BW. The standard setters use SAP NLS and SAP NLS runs on SAP IQ. My advice to others is if they have SAP BW, then they should use SAP IQ, but if they have SAP BW, but have other SAP systems that might not need SAP IQ, they can look for other options. I rate SAP IQ a seven out of ten. Overall the solution is easy to use and highly stable.
