We were able use all our systems without having any problems at first, but then we started getting errors from one of them (SAP). The support team was very helpful when trying resolve this error by pointing us towards where it should be installed again or providing some suggestions as well for future updates because they knew what files would help fix that problem down there too! Not much I dislike about CELANTRA SYSTEM really!! It helped my business out quite alot while using SAP products which is usually difficult sometimes so far everything has been great since implementing their system into ours!
