I like this forum support but I have some thing critical which i have posted but not get solution for that based on that analyse only we are going to buy this product.
For questions in a pre-sales situation, I recommend contacting a Camunda sales representative who can help you get the answers you need. We operate this forum on a best effort basis. Due to the sheer volume of questions and/or low quality of questions, some may remain unanswered.
How can you make it more likely to have your questions answered here?
If you have a problem, post the exact steps to reproduce and/or provide an automated test case
Please do not apply pressure. It will likely only have the opposite effect.
And again, even if you follow these steps, an answer here is not guaranteed. Contact Camunda sales, consulting or Camunda partners for commercial support.
