Prior to implementing SAP, I used some local ERPs but finally, I found this to be the most powerful platform. So I switched from local ERPs to the SAP.

The main difference I've seen between products is the robustness and principle validation and the permission to production, which is very much under our control. It can add complexity and make things a little cumbersome like with SAP but it's also a guarantee of readability and strength. You have to weigh up complexity against more user friendly systems which are prone to mistakes. 

Previously, we were using IBM tools for reporting. But these were not analytical tools. It was a programming language which we used it to develop reports. It did not have these analytical features that BW has like drilling down or across.

Previously we did not use another solution, we have always worked with SAP.

Previously we were developing reports using RPG language on AS/400. It did not have data warehousing and analytic features.

No previous solution was in place.
